Assembly Measuring Tool Power Supply The measuring tool can be operated either with conventional non-rechargeable batteries or with a Bosch lithium-ion bat- tery. Do not use any commercially available rechargeable batter- ies (e.g. nickel metal hydride). Operation with Rechargeable Battery u Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your measuring tool. Note: The use of batteries unsuitable for your measuring tool can lead to malfunctions or damage to the measuring tool. Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using your tool for the first time. The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery. The lithium-ion battery is protected against deep discharge by the "Electronic Cell Protection (ECP)". A protective circuit switches the measuring tool off when the battery is drained. u Do not switch the measuring tool back on after it has been switched off by the protective circuit. This can damage the battery. Battery charge indicator If the rechargeable battery is removed from the measuring tool, its state of charge may be indicated by the green LEDs of the battery charge indicator on the battery. Press the button for the battery charge indicator or to show the state of charge. If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced. Battery model GBA 18V...

Only store the battery within a temperature range of −20 to 50°C. Do not leave the battery in your car in the summer, for example. Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry. A significantly reduced operating time after charging indic- ates that the battery has deteriorated and must be replaced. Follow the instructions on correct disposal. Operation with Non-Rechargeable Batteries It is recommended that you use alkaline manganese batter- ies to operate the measuring tool. Put the batteries into the battery adapter(22). Make sure that the polarity is correct and corresponds to the diagram on the battery adapter. u The battery adapter is intended only for use in desig- nated Bosch measuring tools and must not be used with power tools. Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity. u Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The bat- teries can corrode and self-discharge during prolonged storage in the measuring tool. Changing the batteries/rechargeable battery (seefigureA) To replace the batteries/rechargeable battery, move the locking mechanism(2) of the battery compartment cover into position and open the battery compartment cover(1). Bosch Power Tools 1 609 92A 6AE | (28.05.2021)40 | English Insert either a charged rechargeable battery(24) or the bat- tery adapter(22) with fitted batteries into the battery com- partment until you feel it click into place. To remove the rechargeable battery(24) or battery adapter(22), press the release button(23) and pull the re- chargeable battery or battery adapter out of the battery compartment. Do not use force to do this. Close the battery compartment cover(1) and move the lock- ing mechanism(2) into position . Battery Charge Indicator The battery charge indicator(d) will indicate the state of charge of the batteries/rechargeable batteries on the dis- play: Indicator Capacity 60 − 100% 30 − 60% 5 − 30% 0 − 5% If the batteries or rechargeable bat- tery are empty, a warning message will appear for a few seconds and the status indicator(12) will flash red quickly. The measuring tool will then switch itself off. Remote control power supply Using alkali-manganese batteries is recommended to oper- ate the remote control. Turn the locking mechanism(37) of the battery compart- ment cover into position (e.g. using a coin). Open the battery compartment cover(39) and insert the batteries. When inserting the batteries, ensure that the polarity is cor- rect according to the illustration on the inside of the battery compartment. Close the battery compartment cover(39) and turn the lock- ing mechanism(37) of the battery compartment cover into position . u Remove the batteries from the remote control when not using it for longer periods. The batteries can cor- rode and self-discharge during prolonged storage in the remote control. Note: The Bluetooth® function remains active as long as bat- teries are fitted in the remote control. The batteries can be removed in order to prevent energy consumption by this function. Operation u Protect the measuring tool and remote control against moisture and direct sunlight. u Do not expose the measuring tool or remote control to any extreme temperatures or variations in temperat- ure. For example, do not leave them in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool and the remote control to adjust to the ambient temperature before putting them into op- eration. Before continuing work with the measuring tool, always perform an accuracy check (see "Accuracy Check of the Measuring Tool", page47). The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature. u Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see "Accuracy Check of the Measuring Tool", page47). Starting Operation of the remote control The remote control will only work if it is fitted with batteries that are sufficiently charged. To activate the remote control, press any button on the re- mote control. The status of the axes on the rotary laser is called up and displayed in the (33) and (34)status indicat- ors on the remote control. Provided the status indicators are lit up, the relevant setting on the rotary laser is changed with every subsequent press of a button on the remote control. The signal transmission indicator(32) on the remote control lights up to show that a signal is being transmitted. In order to save energy, the remote control is deactivated after a short time and the (33) and (34)status indicators go out again. It is not possible to switch the measuring tool on/off with the remote control. Starting Operation of the rotary laser u Keep the work area free from obstacles that could re- flect or obstruct the laser beam. For example, cover any reflective or shiny surfaces. Do not measure through panes of glass or similar materials. The meas- urements may be distorted by a reflected or obstructed laser beam. Setting up the measuring tool Horizontal position Vertical position Position the measuring tool on a stable surface in the hori- zontal or vertical position, mount it on the tripod(43) or on the wall mount(44) with the alignment unit. Due to its high levelling accuracy, the measuring tool is very sensitive to knocks and vibrations and changes in position. Take care, therefore, that the measuring tool is stable to avoid interruptions to the operation caused by relevelling. 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 41 Operating the measuring tool The main functions of the measuring tool are controlled by the buttons on the measuring tool and the remote control(40). Additional functions are available via the re- mote control(40), the laser receiver(41), or via the Bosch Levelling Remote App (see "Overview of control options for the functions", page53). For the indicator on the measuring tool's display(15), the following applies: – The current settings for this function will be indicated when a function button (e.g. the line operation button(5)) is pressed for the first time. The settings will be changed the next time a function button is pressed. – In the lower part of the display, softkey symbols(i) are shown in various menus. The corresponding function keys (softkeys) arranged around the display can be used to execute the functions represented by the symbols(i) (see figure B). Depending on the corresponding menu, the symbols show the usable function buttons (e.g. the rotational operation button in the rotational operation menu(6)) or additional functions such as Next ( ), Back ( ) or Confirm ( ). – The softkey symbols(i) also make it easy to recognise whether the Slope button down/Button for clockwise ro- tation (3) and Slope button up/Button for anticlockwise rotation (4) buttons in the current menu are used to slope downwards (▼) or slope upwards (▲) or to turn in a clockwise ( ) or anticlockwise ( ) direction. – The display will automatically go back to the start screen fiveseconds after the last press of a button. – The display(15) will light up with every press of a button or signal that reaches the measuring tool. The light will go out approximately oneminute after the last press of a but- ton. Tilting or rotation in various functions can be accelerated if the respective tilting or rotation buttons on the measuring tool or the remote control are held down for longer. All functions are reset to their standard setting when the measuring tool is switched off. Switching On and Off Note: After the first time the tool is started up and before be- ginning work, you should always perform an accuracy check (see "Accuracy Check of the Measuring Tool", page47). To switch on the measuring tool, press the on/off button(11). A start sequence will appear for a few seconds, followed by the start screen. The measuring tool emits the variable laser beam(8) and the upwards plumb point(10) from the outlet apertures(9). u Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance). The levelling starts automatically and is shown by the flashing symbol for levelling in the display, the flashing laser beams and the status indicator(12) that is flashing green (see "Automatic Levelling", page44). After levelling has successfully been completed, the start screen will ap- pear, the laser beams will light up con- tinuously, rotation will start and the status indicator(12) will light up green continuously. u Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam. To switch off the measuring tool, press and hold the on/off button(11) until the switch-off symbol appears on the display. If the maximum permitted operating temperature of 50°C is exceeded, a warning message will appear for a few seconds and the status indicator(12) will flash red. The measuring tool will then shut down in order to protect the laser diode. Once it has cooled down, the measuring tool is operational again and can be switched back on. Establishing a connection to the remote control/laser receiver In the default factory setting, the measuring tool and the re- mote control(40) and laser receiver(41) supplied are already connected via Bluetooth®. To connect the remote control or the laser receiver, press and hold the Bluetooth® button(7) until the symbol for establishing a connection with the remote control/laser receiver appears on the display. To establish a connection to the remote control, press and hold the button for anticlockwise rotation(29) and the but- ton for clockwise rotation(36) on the remote control at the same time until the status indicators(33) and(34) begin to flash. While the connection to the remote control is being es- tablished, the status indicators on the remote control will al- ternately flash green. To establish a connection to the laser receiver, press and hold the X‑axis and Y‑axis buttons on the laser receiver at the same time until the message that a connection has been es- tablished appears on the display of the laser receiver. To do this, consult the operating instructions for the laser receiver. Bosch Power Tools 1 609 92A 6AE | (28.05.2021)42 | English It will be confirmed on the display whether a connection has successfully been established to the remote con- trol or the laser receiver. If the attempt to establish a connec- tion to the remote control is success- ful, the status indicators(33) and (34) on the remote control will light up green for 3s. If no connection could be established, an error message will appear on the display. If the attempt to establish a connec- tion to the remote control is not successful, status indicators(33) and(34) on the remote control will light up red for 3s. Two laser receivers can be connected to and work with the measuring tool at the same time. If other remote controls or laser receivers are connected, the oldest connection will then be deleted. Remote control via Bosch Levelling Remote App The measuring tool is equipped with a Bluetooth® module which uses radio technology to enable remote control via a smartphone with a Bluetooth® interface. The Bosch Levelling Remote App application (app) is re- quired to use this function. You can download this in the app store for your terminal device (Apple App Store, Google Play Store). Information about the system requirements for a Bluetooth® connection can be found on the Bosch website at www.bosch‑pt.com When remote controlling via Bluetooth®, poor reception con- ditions can cause time delays between the mobile terminal device and the measuring tool. The Bluetooth® function is switched on by default. To switch off Bluetooth® to control remotely via the app, press the Bluetooth®button(7). The Bluetooth® connection indicator(b) will go out on the start screen. To switch back on Bluetooth® to con- trol remotely via the app, briefly press the Bluetooth®button(7). The symbol for establishing a connection to the smartphone will appear on the dis- play. Ensure that the Bluetooth® interface is activated on your mobile device. It will be confirmed on the display whether a connection has successfully been established. The existing con- nection is visible on the Bluetooth® connection indicator(b) on the start screen. If no connection could be established, an error message will appear on the display. The connection between mobile end device and measuring tool is established after the Bosch application has started. If multiple active measuring tools are found, select the appro- priate measuring tool. A connection will be established auto- matically if only one active measuring tool is found. The Bluetooth® connection may be interrupted if the dis- tance between the measuring tool and the mobile device is too great or is blocked, and if there are any sources of elec- tromagnetic interference. In this case, another attempt to establish a connection will automatically begin. Sleep mode During breaks from work, you can set the measuring tool to sleep mode. All your settings will still be saved. To switch on sleep mode, briefly press the on/off button(11). In the menu which subsequently appears, press the on/off button(11) as many times as needed until sleep mode has been selected. Confirm your selection with by pressing the slope button(14). Alternatively, you can switch on sleep mode by pressing the sleep mode button(27) on the remote control. When sleep mode is switched on, the sleep mode symbol will be indicated on the display. The status indicator(12) will slowly flash green. The shock-warning function will re- main activated and all settings will be saved. To switch off sleep mode, briefly press the on/off button(11) on the measuring tool or press the sleep mode button(27) on the remote control. You can also switch off the measuring tool while it is in sleep mode. Press and hold the on/off button(11) until the switch-off symbol appears on the display. All other buttons on the measuring tool and the remote control will be deactiv- ated. It is also possible to switch sleep mode on and off via the Bosch Levelling Remote App. Locking the keyboard The keyboard of the measuring tool and the remote control can be locked via the Bosch Levelling Remote App. The keyboard lock symbol will appear on the measuring tool's display. The keyboard can be unlocked as follows: – via the Bosch Levelling Remote App, 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 43 – by switching the measuring tool on and off via the on/off button(11) – or by pressing the ▲/ (4) and ▼/ (3) buttons on the measuring tool at the same time. Operating Modes Alignment of X and Y-axis

(16) (16) The alignment of the X and Y axes is marked on the housing above the rotation head. The markings are exactly above the alignment notches(16) at the bottom edge of the housing and on the lower handle. The measuring tool can be aligned along the axes by using the alignment notches. Operating modes overview All three operating modes are possible with the measuring tool in horizontal and vertical position. Rotational operation Rotational operation is especially recommen- ded when using the laser receiver. It is possible to select between different rotational speeds. Line operation In this operating mode, the variable laser beam moves within a defined aperture angle. This in- creases the visibility of the laser beam in com- parison to rotational operation. You can select between different aperture angles. Point operation In this operating mode, the best visibility of the variable laser beam can be reached. For ex- ample, it is used to easily project heights or to check building lines. Line and point operation are not suitable for use with the laser receiver(41). Rotational operation Each time after switching on, the measuring tool is in rota- tional operation mode with standard rotational speed (600min

To switch from line operation to rotational operation, press the rotational operation button(6) or the rotational opera- tion button(26) on the remote control. To change the rotational speed, press the rotational operation button(6) or the rotational operation button(26) on the remote control as many times as needed until the required speed is indicated on the display. The set speed can be seen on the rotational speed indicator(h) on the start screen. When working with the laser receiver, the highest rotational speed should be set. When not working with the laser re- ceiver, reduce the rotational speed for improved visibility of the laser beam and use the laser googles(50). Line operation/point operation To switch to line or point operation, press the line operation button(5) or the line operation button(28) on the remote control. To change the aperture angle, press the line operation button(5) or the line operation button(28) on the re- mote control until the required operat- ing mode is indicated on the display. The aperture angle is reduced in stages each time a button is pressed until point operation is achieved. At 360°, the measuring tool is again in rotational operation. The rotational speed is the last set speed. Note: Due to inertia, it is possible for the laser to slightly move beyond the end point of the laser line. Turning the line/point within the rotational plane In line and point operation, the laser line or the laser point can be positioned within the rotational plane of the laser. Ro- tation is possible by 360°. To rotate anticlockwise, press the button (4) on the measuring tool or the button for anticlockwise rotation(29) on the remote control. To rotate clockwise, press the button (3) on the measur- ing tool or the button for clockwise rotation(36) on the re- mote control. Turning the rotational plane when in the vertical position When the measuring tool is in the vertical position, it is pos- sible to rotate the laser point, laser line or rotational plane around the X-axis for easy sighting out or parallel alignment in a range of ±8.5%. To start the function, press the slope button(14) on the measuring tool or the slope button(31) on the remote control. The menu for setting the slope of the Y‑axis will appear and the symbol for the Y‑axis will flash. To rotate the rotational plane, press the ▲ button(4) or the ▼ button(3) on the measuring tool or the up(30) or Bosch Power Tools 1 609 92A 6AE | (28.05.2021)44 | English down(35) slope button on the remote control until the re- quired position is reached. Automatic downwards plumb point function in the vertical position To align the measuring tool against a reference point on the ground when it is in the vertical position, the variable laser beam(8) can be turned downwards to be used as a plumb point. The plumb point function can only be started via re- mote control or theBosch Levelling Remote App app. The variable laser beam plumb point is not self-levelling. Therefore, ensure that the measuring tool is levelled in when starting the plumb point function. To start the downwards plumb point function, press the plumb point func- tion button(25) on the remote con- trol. The plumb point function symbol will appear on the display while the variable laser beam is aligned vertic- ally. After it has been successfully aligned, the plumb point function indicator(e) will appear on the start screen. Automatic Levelling Overview After switching on, the measuring tool checks the horizontal and vertical position and automatically levels out any un- evenness within the self-levelling range of approx. ±8.5% (±5°). The symbol for levelling flashes on the display during levelling. The status indicator(12) on the measuring tool and the status indicator for the re- spective axis((34) or (33)) on the re- mote control flash green at the same time. The rotation is stopped until levelling has been completed and the laser beams are flashing. The start screen will ap- pear after levelling has been successfully completed. The laser beams will light up continuously and rotation will start. The status indicator(12) on the measuring tool and the status indicator for the levelled axis((34) or (33)) on the re- mote control will light up green continuously. If the measuring tool is at a slant of more than 8.5% or is positioned dif- ferently to the horizontal or vertical position, levelling will no longer be possible. An error message will appear on the display and the status indicator(12) will flash red. Reposition the measuring tool and wait for it to re-level. If the maximum levelling time is ex- ceeded, levelling will be discontinued with an error message. Reposition the measuring tool and briefly press the on/off button(11) to restart levelling. Position changes When the measuring tool is levelled in, it continuously checks the horizontal and vertical position. Re-levelling is automatically performed if there are any position changes. Minimal position changes are levelled out without inter- rupting the operation. This automatically compensates sub- soil ground vibrations or weather influences. For larger position changes, the rotation of the laser beam will be stopped in order to avoid faulty measurements during the levelling process and the laser beams will flash. The lev- elling symbol appears on the display. The shock-warning function will be actuated, if required. The measuring tool will automatically detect the horizontal or vertical position. To change between the horizontal and the vertical position, switch the measuring tool off, reposi- tion it and switch it on again. If the position is changed without switching on/off, an error message will appear and the status indicator(12) will flash red quickly. Briefly press the on/off button(11) to restart levelling. Shock-warning function The measuring tool has a shock-warning function. After posi- tion changes or shock to the measuring tool, or in case of ground vibrations, it keeps the measuring tool from levelling in at changed positions, and thus prevents errors caused by a change in the measuring tool's position. GRL650CHVG: The shock-warning function operates at two sensitivity levels. After the measuring tool is switched on, the setting defaults to high sensitivity. To activate shock warning: The shock-warning function is switched on by default. It is activated approximately 30s after the measur- ing tool has been switched on. During activation, the shock-warning function indicator(c) will flash on the display. The indicator lights up con- tinuously after activation. Shock warning actuated: If the position of the measuring tool is changed or a severe knock is re- gistered, the shock warning will be ac- tuated. The laser will stop rotating and an error message will appear. The status indicator(12) will quickly flash red and a warning signal will sound at a fast rate. Confirm the warning message with by pressing the slope button(14) on the measuring tool or the slope button(31) on the remote control. When working with automatic level- ling (including slope operation), levelling is automatically re- started. 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 45 Now check the position of the laser beam at a reference point and, if necessary, correct the height or alignment of the measuring tool. To adjust/switch off the shock-warning function: On the start screen, the current setting is shown with the shock-warning indicator(c): Shock-warning function is switched on at high sensitivity. GRL650CHVG: Shock-warning function is switched on at reduced sensitivity. Shock-warning function is switched off. (GRL 600 CHV) (GRL 650 CHVG) Briefly press the on/off button(11) to adjust the shock-warning function setting. Then press the on/off button(11) in the menu which sub- sequently appears as many times as needed until the required setting has been selected. Confirm your selection with by pressing the slope button(14). If the shock-warning function has been switched on, it will be activated after approximately 30seconds. Slope operation in the horizontal position In the measuring tool's horizontal position, the X-axis and the Y-axis can be tilted independently of each other in a range of ±8.5%. To tilt the X-axis, press the slope button(14) on the measuring tool or the slope button(31) on the remote control once. The menu for setting the slope of the X-axis will appear. Set the required slope by using the buttons ▲(4) or ▼(3) on the measuring tool or using the up(30) or down(35) slope buttons on the remote control. Pressing both slope buttons on the measuring tool or on the remote control at the same time resets the slope back to 0.00%. To tilt the Y‑axis, press the slope button(14) on the measuring tool or the slope button(31) on the remote control again. The menu for setting the slope of the Y-axis will appear. Set the required slope in the same way as outlined for the X‑axis. The selected slope is implemented on the measuring tool a few seconds after the last press of a button. Both the laser beam and the symbol for setting the slope on the display will flash until the process of setting the slope has been completed. After the process of setting the slope has been completed, the set slope val- ues of both axes will be shown on the start screen. The status indicator(12) on the measuring tool will light up red continuously. On the remote control, the status indicator for the tilted axis ((34) and/or (33)) will light up red continuously. Slope memory for slope operation in horizontal position (GRL650CHVG) The measuring tool saves the four most recently used slope values of both axes. As an alternative when readjusting the slopes, you can apply these saved slope combinations. Start the slope operation for the X‑axis (see "Slope operation in the horizontal position", page45). To call up the slope memory, press the line operation button(5) on the meas- uring tool or the line operation button(28) on the remote control. To select one of the four saved com- binations, press the line operation button(5) on the measuring tool or the line operation button(28) on the remote control as many times as needed until the required combination is indicated on the display. Confirm the selection by pressing the slope button(14) on the measuring tool ( ) or the slope button(31) on the re- mote control. The slope combination is implemented on the measuring tool a few seconds after the button is pressed (see "Slope operation in the horizontal position", page45). To set a value other than one of those saved, press the ▲ button (4) on the measuring tool ( ) or the slope up button(30) on the remote control. The indicator returns to the slope operation settings menu (see "Slope operation in the horizontal position", page45). SlopeProtect Temperature changes in the measuring tool can have effects on the set slope of the axes. To avoid measurement inaccuracies, the slope of the axes is readjusted when exceeding the set temperature difference. The measuring tool is levelled in, then it returns to slope op- eration with the previously set values. The slope is reset at temperature changes of ≥5°C. GRL650CHVG: Using the Bosch Levelling Remote App, the temperature difference can be lowered to 2°C or the SlopeProtect function can be switched off altogether. This setting is not saved when the measuring tool is switched off. Manual operation The automatic levelling of the measuring tool can be switched off (manual operation): Bosch Power Tools 1 609 92A 6AE | (28.05.2021)46 | English – in the horizontal position for both axes independently of each other, – in the vertical position for the X‑axis (the Y‑axis cannot be levelled in the vertical position). It is possible to set up the measuring tool at any inclination in the manual operation mode. The axes can also be tilted inde- pendently of each other in a range of ±8.5% on the measur- ing tool. In manual operating mode, the slope value of an axis will not be shown on the display. The status indicator(12) on the measuring tool will light up red continuously if – at least one axis is set to manual operating mode in the horizontal position, – the X-axis is set to manual operating mode in the vertical position. The Y-axis status indicator(34) or the X-axis status indicator(33) on the remote control light up red continu- ously if the relevant axis is set to manual operating mode. Manual operation cannot be started via remote control. Manual operation in the horizontal position To switch off automatic levelling, press the manual operation button(13) as many times as needed until the required settings combina- tion for both axes is achieved. In the il- lustrated example, automatic levelling for the X-axis is switched off and the Y-axis continues to be levelled. To tilt an axis with automatic level- ling switched off, press the slope button(14) while the menu for manual operating mode is dis- played. If automatic levelling is only switched off for one axis, it will only be possible to change the slope of that axis. When manually operating both axes, it is possible to switch between the axes by pressing the slope button(14) again. The symbol for the axis whose slope can be changed will flash. Tilt the selected axis using the ▲(4) or ▼(3) buttons until the required position is reached. Manual operation in the vertical position To switch off automatic levelling for the X-axis, press the manual operation button(13) once. (The Y‑axis cannot be levelled when in the vertical posi- tion.) To tilt the X-axis without using auto- matic levelling, press the slope button(14) while the manual oper- ating mode menu is displayed. The symbol for the X-axis will flash on the display. Tilt the X-axis using the ▲(4) or ▼(3) buttons until the re- quired position is reached. To rotate the Y-axis, press the slope button(14) again while manual oper- ating mode menu is displayed. The symbol for the Y-axis will flash on the display. Rotate the Y-axis using the ▲(4) or ▼(3) buttons until the required position is reached. Functions CenterFind mode In CenterFind mode, the measuring tool automatically at- tempts to align the laser beam to the centre line of the laser receiver by moving the rotation head up and down. The laser beam can be aligned to the X‑axis or the Y‑axis of the meas- uring tool. CenterFind mode is started at the laser receiver. For this, please read and observe the operating instructions for the laser receiver. During the search, the CenterFind symbol for one or both axes will ap- pear on the display of the measuring tool and the status indicator(12) will flash red. If the laser beam was able to be aligned to the centre line of the laser receiver, the CenterFind mode will automatically finish and the slope found will be indicated on the start screen. If the laser beam could not be aligned with the centre line of the laser re- ceiver, the rotation of the laser beam is stopped and an error message ap- pears in the display. Press any button to close the error message. The cor- responding axis is levelled in again to 0%. Check whether the measuring tool and laser receiver have been set up correctly, and restart the mode. The laser re- ceiver must be situated within the pivoting range of ±8.5% of the measuring tool. Note: When using CenterFind mode, the setting of both axes can change, even if one of the axes has not been aligned with the laser receiver. 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 47 CenterLock mode (GRL650CHVG) In CenterLock mode, the measuring tool automatically at- tempts to align the laser beam to the centre line of the laser receiver by moving the rotation head up and down. In con- trast to the CenterFind mode, the position of the laser re- ceiver is continuously checked and the inclination of the measuring tool is automatically adjusted. The slope meas- urements are not shown on the display. u When working in CenterLock mode, take care to en- sure that the measuring tool and laser receiver are not accidentally moved. The automatic adjustment of the in- clination for every position change can result in measure- ment errors. The laser beam can be aligned to the X‑axis or the Y‑axis of the measuring tool. CenterLock mode is started and finished at the laser re- ceiver. For this, please read and observe the operating in- structions for the laser receiver. During the search, the CenterLock symbol for one or both axes will ap- pear on the display of the measuring tool and the status indicator(12) will flash red. If the laser beam could be aligned to the centre line of the laser receiver, the CenterLock symbol for one or both axes will appear on the start screen. The slope measurements are not shown. If the laser beam could not be aligned with the centre line of the laser re- ceiver, the rotation of the laser beam is stopped and an error message ap- pears in the display. Press any button to close the error message. The cor- responding axis is levelled in again to 0%. Check whether the measuring tool and laser receiver have been set up correctly, and restart the mode. The laser re- ceiver must be situated within the pivoting range of ±8.5% of the measuring tool. Note: When using CenterLock mode, the setting of both axes can change, even if one of the axes has not been aligned with the laser receiver. Mask mode (seefigureC) In rotational operation, the variable laser beam(8) can be switched off for one or more quadrants of the rotational plane. This makes it possible to limit the risk related to laser beams to certain areas. Interference from the laser beam that affects other tools or interference with the laser receiver by unintended reflections can also be avoided. The switching off of individual quadrants can only be con- trolled by using the Bosch Levelling Remote App. The quadrants in which the laser beam is visible can be seen in the laser operating mode indicator(a) on the start screen. Accuracy Check of the Measuring Tool The following tasks should be performed only by well-trained and qualified persons. The legalities with regard to perform- ing an accuracy check or calibration of a measuring tool must be known. Influences on Accuracy The largest influence is exerted by the ambient temperature. In particular, temperature differences that occur from the ground upwards can refract the laser beam. In order to minimise thermal influences resulting from heat rising from the floor, it is recommended that you use the measuring tool on a tripod. In addition, position the measur- ing tool in the centre of the work surface, wherever this is possible. In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the levelling accuracy each time before beginning work. If the measuring tool exceeds the maximum deviation for the measuring procedures described below, perform a calibra- tion (see "Calibrating the measuring tool", page48) or have the measuring tool checked by a Bosch customer service agent. Checking the levelling accuracy in a horizontal position For a reliable and precise result, it is recommended that you check the levelling accuracy on a free measuring distance of30m on firm ground in front of a wall. Carry out a com- plete measuring procedure for each of the two axes. – Mount the measuring tool in a horizontal position 30m from the wall on a tripod, or place it on a firm, level sur- face. Switch on the measuring tool. 30 m – Once levelling is complete, mark the centre of the laser beam on the wall (pointⅠ). Bosch Power Tools 1 609 92A 6AE | (28.05.2021)48 | English 180°

– Turn the measuring tool 180° without adjusting the height. Allow it to level in and mark the centre point of the laser beam on the wall (pointⅡ). Ensure that pointⅡ is vertically over or under pointⅠ. Repeat the measuring process for the other axis. To do this, turn the measuring tool by 90° before beginning the meas- urement. The maximum permitted deviation on the 30m measuring distance is as follows: ±1.5mm. The discrepancyd between pointsⅠ and Ⅱ must therefore amount to no more than 3mm for each of the two measuring processes. Checking the levelling accuracy in the vertical position For this check, you will need a free measuring distance on firm ground in front of a 10-metre tall wall. Fix a plumb line to the wall. – Position the measuring tool in the vertical position on a firm, level surface. Switch the measuring tool on and al- low it to level in. 10 m

– Set up the measuring tool so that the laser beam meets the plumb line at the exact centre of the upper end. The discrepancyd between the laser beam and the plumb line at the lower end of the line reveals the measuring tool's deviation from the vertical. For a 10m high measuring distance, the maximum permit- ted deviation is as follows: ±1mm. The discrepancyd must therefore be no more than 1mm. Calibrating the measuring tool The following tasks should be performed only by well-trained and qualified persons. The legalities with regard to perform- ing an accuracy check or calibration of a measuring tool must be known. u Perform calibration of the measuring tool with ex- treme precision or have the measuring tool checked by a Bosch customer service agent. Inaccurate calibra- tion leads to incorrect measuring results. u Only start the calibration if you have to perform a cal- ibration of the measuring tool. As soon as the measur- ing tool is in calibration mode, you must perform the cal- ibration meticulously to the end in order to ensure that no incorrect measuring results are produced afterwards. Check the levelling accuracy after every calibration (see "Accuracy Check of the Measuring Tool", page47). If the de- viation is outside the maximum permitted limits, have the measuring tool checked by a Bosch customer service agent. X-axis and Y-axis Calibration The GRL600CHV can only be calibrated using the LR60 laser receiver, and the GRL650CHVG can only be calibrated using the LR65G. The laser receiver must be connected to the measuring tool via Bluetooth® (see "Establishing a con- nection to the remote control/laser receiver", page41). The positions of the measuring tool and laser receiver cannot be changed during calibration (with the exception of the alignments or rotations described). Therefore position the measuring tool on a firm, level surface and secure the laser receiver. Calibration should be performed via the Bosch Levelling Remote App if possible. There is less likelihood of error when controlling the tool via the app. Otherwise, the meas- uring tool's position can be altered if buttons are pressed without due care. For calibration without the app, the corresponding buttons on the measuring tool must be pressed. It is not possible to use the remote control during calibration. A free measuring distance of 30m on a firm surface is re- quired. If no such measuring distance is possible, calibration can also be performed with lower levelling accuracy on a measuring distance of 15m. Mounting the measuring tool and the laser receiver for calibration: Mount the measuring tool in the horizontal position 30m or 15m from the laser receiver on the tripod(43) or position it on a firm, level surface. Secure the laser receiver at the correct height: – Either to a wall or to another surface by means of magnets or the suspension hook on the laser receiver, – or to a securely fastened aid with the holder for the laser receiver. To do this, consult the operating instructions for the laser re- ceiver. 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 49 Aligning the measuring tool for calibration:

Align the measuring tool so that the X-axis indicator imprin- ted on the measuring tool with the "+" side is pointing to the laser receiver. For this, the X‑axis must be perpendicular to the laser receiver. To start calibration: – For calibration via the Bosch Levelling Remote App: Switch on the measuring tool. Start calibration in the app. Follow the instructions in the app. – For calibration without the app: Switch on the measuring tool and the laser receiver. Make sure that both of these are connected via Bluetooth®. Start calibration by press- ing the on/off button on the laser receiver and the CenterFind mode button on the laser receiver at the same time. "CAL" will appear on the display of the laser receiver. Press and hold the CenterFind mode button on the laser re- ceiver to cancel the calibration, if required. To perform calibration without the app: In the menu that appears in the meas- uring tool display after starting calib- ration, select the existing distance between the measuring tool and the laser receiver. To do this, press the ▲ button (4) or the ▼ button (3). Con- firm your selection with by pressing the slope button(14). To confirm the selected measuring distance including the corresponding levelling accuracy ( ), press the slope button(14) in the menu which subsequently appears. To go back to selecting the measuring distance ( ), press the line operation button(5). Align the height of the laser receiver so that the variable laser beam(8) on the laser receiver is indicated as "centred" (see operating instructions for the laser receiver). Secure the laser receiver at this height. Check whether the measuring tool and laser receiver are aligned with each other, as illustrated on the display (the "+" side of the X-axis is aligned to the laser receiver). Start calibration of the X-axis with by pressing the slope button(14). If this step appears on the display, ro- tate the measuring tool 180° so that the "–" side of the X‑axis is directed at the laser receiver. For each rotation, take care not to change the height and inclination of the measuring tool. Con- firm the rotation with by pressing the slope button(14). Calibration of the X-axis continues. This symbol will appear on the meas- uring tool display if the X-axis has been successfully calibrated. Continue calibration with by pressing the slope button(14). To calibrate the Y-axis, rotate the measuring tool 90° in the direction of the arrow so that the "+" side of the Y‑axis is directed at the laser receiver. Confirm the rotation with by press- ing the slope button(14). If this step appears on the display, ro- tate the measuring tool 180° so that the "–" side of the Y‑axis is directed at the laser receiver. Confirm the rota- tion with by pressing the slope button(14). Calibration of the Y-axis continues. This symbol will appear on the meas- uring tool display if the Y-axis has been successfully calibrated. Finish the calibration of the Y-axis with by pressing the slope button(14). This symbol confirms that the X-axis and the Y-axis have been successfully calibrated with the levelling accuracy selected at the beginning. End the cal- ibration with by pressing the slope button(14). If the calibration has been completed successfully, the measuring tool then automatically switches itself off. Bosch Power Tools 1 609 92A 6AE | (28.05.2021)50 | English The relevant error message will ap- pear in the measuring tool display if calibration of the X‑axis or the Y‑axis has not been successful. "ERR" will appear on the display of the laser re- ceiver. Cancel the calibration with by pressing the button for line operation(5). Make sure that the measuring tool and the laser receiver are aligned correctly (see description above). Restart the calib- ration. If calibration fails again, have the measuring tool checked by a Bosch customer service agent. Z-axis calibration A free measuring distance on firm ground in front of a 10m wall is required for the calibration. Fix a plumb line to the wall. 10 m Position the measuring tool on a firm, level surface. Switch the measuring tool on and allow it to level in. Align the meas- uring tool so that the laser beam is perpendicular to the wall and cuts through the plumb line. Switch the measuring tool off. To start calibration mode, press and hold the slope button(14) and then also briefly press the on/off button(11). The measuring tool is switched on. Allow the measuring tool to level in. Align the laser beam so that it runs as parallel as possible to the plumb line. Tilt the laser beam in the ◀ direction by pressing the ▲ button (4). Tilt the laser beam in the ▶ direction by pressing the ▼ button (3). If it is not possible to align the laser beam in parallel to the plumb line, align the measuring tool to the wall more pre- cisely and start the calibration process again. If the laser beam is aligned in parallel, save the calibration with by pressing the slope button(14). This symbol confirms that the Z-axis has been calibrated successfully. At the same time, the status indicator(12) will flash green three times. End the calibration with by pressing the slope button(14). If the calibration has been completed successfully, the measuring tool then automatically switches itself off. This error message will appear if calib- ration of the Z-axis has been unsuc- cessful. Cancel the calibration with by pressing the button for line operation(5). Ensure that the reference vertical line is in the pivoting range of the rotation head and restart the calibration. Make sure that the measuring tool is not moved during calibration. If calibration fails again, have the measuring tool checked by a Bosch customer service agent. Working Advice u Only the centre of the laser point or laser line must be used for marking. The size of the laser point/the width of the laser line changes depending on the distance. u The measuring tool is equipped with a wireless inter- face. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed. 1 609 92A 6AE | (28.05.2021) Bosch Power ToolsEnglish | 51 Working with the Laser Target Plate The laser target plate(51) improves visibility of the laser beam in unfavourable conditions and at greater distances. The reflective surface of the laser target plate(51) improves visibility of the laser line. The transparent surface enables the laser line to be seen from behind the laser target plate. Working with the Tripod (Accessory) A tripod offers a stable, height-adjustable support surface for measuring. For horizontal operation, place the measuring tool with the 5/8" tripod mount(18) on the thread of the tripod(43). Tighten the measuring tool using the locking screw of the tripod. For vertical operation, use the 5/8" tripod mount(20). On a tripod featuring a measuring scale on its extender, you can set the height deviation straight away. Roughly align the tripod before switching on the measuring tool. Laser Goggles (Accessory) The laser goggles filter out ambient light. This makes the light of the laser appear brighter to the eye. u Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation. u Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours. Working with a wall mount and alignment unit (seefigureD) The measuring tool can be secured to the wall using the wall mount with the alignment unit(44). Using the wall mount is recommended, e.g. when working above the maximum ex- tension height of tripods, or when working on unstable sur- faces without a tripod. Fasten the wall mount(44) to a wall using screws through the fixing holes(45). Fit the wall mount as vertical as pos- sible and ensure it is mounted in a stable way. Screw the 5/8" wall mount screw(48) into the horizontal tri- pod mount(18), depending on the requirements of the task, or the vertical tripod mount(20) on the measuring tool. Using the alignment unit allows the measuring tool to be moved in a range of approx. 13cm with respect to height. Press the button(46) and move the alignment unit to roughly the required height. It is possible to align the laser beam precisely to a reference height using the fine adjust- ment screw(47). Working with the measuring rod (accessory) (seefigureE) To check levels or apply slopes, it is recommended to use the measuring rod(42) together with the laser receiver. A relative measuring scale is incorporated at the top of the measuring rod(42). You can preselect its zero at the bottom on the extender. This enables you to read deviations from the target height straight away. Example applications Projecting/checking heights (seefigureF) Position the measuring tool in the horizontal position on a firm support or mount it on a tripod(43) (accessory). Working with a tripod: Set the laser beam at the required height. Project or check the height at the target location. Working without a tripod: Determine the height difference between the laser beam and the height at the reference point using the laser target plate(51). Project or check the height difference measured at the target location. Parallel Alignment of Upwards Plumb Point/Projecting Right Angles (seefigureG) When right angles are to be projected or partition walls are to be aligned, the upwards plumb point(10) must be aligned in parallel, meaning at the same distance to a reference line (e.g. a wall). For this, set up the measuring tool in the vertical position and position it in such a manner that the upwards plumb point runs approximately parallel to the reference line. For the exact positioning, measure the clearance between the upwards plumb point and reference line directly on the measuring tool using the laser target plate(51). Measure the clearance between the upwards plumb point and reference line again as far away as possible from the measuring tool. Align the upwards plumb point in such a manner that it has the same clearance to the reference line as when measured directly at the measuring tool. The right angle to the upwards plumb point(10) is indicated by the variable laser beam(8). Indicating a perpendicular/vertical plane (seefigureG) To indicate a perpendicular or a vertical plane, set up the measuring tool in the vertical position. When the vertical plane is supposed to run at a right angle to a reference line (e.g. a wall), align the upwards plumb point(10) with this reference line. The perpendicular plane is indicated by the variable laser beam(8). Aligning a Perpendicular/Vertical plane (seefigureH) To align the vertical laser line or the rotational plane against a reference point on a wall, set up the measuring tool in the vertical position, and roughly align the laser line or the rota- tional plane with the reference point. For precise alignment with the reference point, turn the rotational plate around the X-axis (see "Turning the rotational plane when in the vertical position", page43). Working without the laser receiver Under favourable light conditions (dark environment) and for short distances, it is possible to work without the laser receiver. For improved visibility of the laser beam, either se- lect line operation or point operation and rotate the laser beam to the target location. Working with the laser receiver (seefigureE) In unfavourable lighting conditions (bright environment, dir- ect sunlight) and for larger distances, use the laser receiver Bosch Power Tools 1 609 92A 6AE | (28.05.2021)52 | English to improve detection of the laser beam(41). When working with the laser receiver, select rotational operation with the highest rotational speed. Working outdoors (seefigureE) The laser receiver(41) should always be used when working outdoors. When working on unstable ground, mount the measuring tool on the tripod(43). Always work with the shock-warning function activated in order to avoid faulty measurements in case of ground movements or shocks to the measuring tool. Setting up formwork (seefigureI) Mount the measuring tool in the horizontal position on a tripod(43) and set up the tripod outside the formwork area. Select rotational operation. Secure the laser receiver(41) to a measuring rod(42) with the holder. Position the measuring rod on a reference point for the formwork. Align the height of the laser receiver on the measuring rod so that the variable laser beam(8) of the measuring tool is in- dicated as "centred" (see operating instructions for the laser receiver). Then position the measuring rod with the laser receiver, one after the other, at different test locations on the formwork. Make sure that the laser receiver remains in the same posi- tion on the measuring rod. Correct the height of the formwork until the laser beam is in- dicated as "centred" at all test locations. Checking slopes (seefigureJ) Mount the measuring tool in the horizontal position on a tripod(43). Select rotational operation. Set up the tripod with the measuring tool so that the X-axis is aligned with the slope that is to be checked. Set the target slope as the slope for the X-axis (see "Slope operation in the horizontal position", page45). Secure the laser receiver(41) to a measuring rod(42) with the holder. Place the measuring rod at the base of the slope surface. Align the height of the laser receiver on the measuring rod so that the variable laser beam(8) of the measuring tool is in- dicated as "centred" (see operating instructions for the laser receiver). Then position the measuring rod with the laser receiver, one after the other, at different test locations on the slope sur- face. Make sure that the laser receiver remains in the same position on the measuring rod. If the slope of the plane is correct, the laser beam will be in- dicated as "centred" at all test locations.
