The serial number (10) on the type plate is used to clearly identify your measuring tool. Bosch Power Tools 1 609 92A 7AN | (14.12.2021)26 | English Assembly Inserting/changing the batteries It is recommended that you use alkaline manganese batteries to operate the measuring tool. To open the battery compartment cover(11), press on the locking mechanism(12) and remove the battery compartment cover. Insert the batteries. When inserting the batteries, ensure that the polarity is correct according to the illustra- tion on the inside of the battery compartment. If the batteries become weak, the status indicator(7) will flash. The measuring tool can still be operated for approximately 1hour after the first flash. Always replace all the batteries at the same time. Only use batteries from the same man- ufacturer and which have the same capacity. u Take the batteries out of the measuring tool when you are not using it for a pro- longed period of time. The batteries can corrode and self-discharge during pro- longed storage in the measuring tool. Working with the RM1rotating mount (seefiguresA–B) Using the rotating mount(13), you can rotate the measuring tool 360°. This enables you to set up the laser lines precisely, without having to change the position of the measuring tool. Place the measuring tool with the guide groove(17) on the guide rail(14) of the rotating mount(13) and slide the measuring tool all the way onto the platform. To disconnect the measuring tool, pull it off the rotating mount in the opposite direction. Rotating mount positioning options: – Standing on a flat surface, – Screwed to a vertical surface, – On metallic ceiling strips using the ceiling clip(18), – On metallic surfaces using the magnets(16). u Keep your fingers away from the rear side of the magnetic accessory while at- taching the accessory to surfaces. The strong pulling force of the magnets may jam your fingers. 1 609 92A 7AN | (14.12.2021) Bosch Power ToolsEnglish | 27 Operation Starting Operation u Protect the measuring tool from moisture and direct sunlight. u Do not expose the measuring tool to any extreme temperatures or fluctuations in temperature. For example, do not leave it in a car for extended periods of time. If it has been subjected to significant fluctuations in temperature, first allow the measur- ing tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work (see "Accuracy Check of the Measuring Tool", page29). The precision of the measuring tool may be compromised if exposed to extreme tem- peratures 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", page29). u Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements. Switching On/Off To switch on the measuring tool, slide the on/off switch(2) to the " On" position (for working with the pendulum lock) or to the " On"position (for working with automatic levelling). The status indicator(7) lights up. As soon as it is switched on, the measuring tool emits laser lines from the outlet apertures(1). u Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance). To switch off the measuring tool, slide the on/off switch (2) to the "Off" position. The status indicator(7) goes out. The pendulum unit is locked when the tool is switched off. 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. If the maximum permitted operating temperature of 50 °C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is opera- tional again and can be switched back on. Automatic shut-off If no button on the measuring tool is pressed for approx. 120min, the measuring tool will automatically switch itself off to preserve battery life. Bosch Power Tools 1 609 92A 7AN | (14.12.2021)28 | English To switch the measuring tool back on after it has been automatically switched off, you can either slide the on/off switch(2) to the "Off" position first and then switch the meas- uring tool back on, or press either the vertical mode button(5) or the horizontal mode button(6) once. To deactivate automatic shut-off, hold down the horizontal mode button(6) for at least threeseconds (with the measuring tool switched on). If automatic shut-off is deactiv- ated, the laser lines will flash briefly as confirmation. Note: If the operating temperature exceeds 45°C, automatic shut-off can no longer be deactivated. To activate the automatic shut-off function, switch the measuring tool off and on again. Operating Modes The measuring tool has several operating modes, which you can switch between at any time: – Cross-line mode (see figureC): Generates one horizontal and one vertical laser line – Horizontal mode (see figureD): Generates one horizontal laser line – Vertical mode (see figureE): Generates one vertical laser line After switching on, the measuring tool is in cross-line operating mode. Using the buttons for horizontal mode(6) and vertical mode(5), you can switch the horizontal and vertical laser lines on and off independently of one another. All operating modes can be selected with both automatic levelling or the pendulum lock. Automatic Levelling Working with automatic levelling Position the measuring tool on a level, firm surface or attach it to the rotating mount(13) or the tripod(23). For work with automatic levelling, slide the on/off switch(2) to the " On" position. The automatic levelling function automatically compensates irregularities within the self- levelling range of ±4°. The levelling is finished as soon as the laser lines stop moving. If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than4°from the horizontal plane, the laser beams will flash quickly. If this is the case, set up the measuring tool in a level position and wait for the self-level- ling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams will light up continuously. 1 609 92A 7AN | (14.12.2021) Bosch Power ToolsEnglish | 29 In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again. Upon levelling, check the position of the laser beams with regard to the reference points to avoid errors arising from a change in the measuring tool's position. Working with the pendulum lock For work with the pendulum lock, slide the on/off switch(2) to the " On" position. The pendulum lock indicator(8) lights up red and the laser lines continuously flash slowly. For work with the pendulum lock, automatic levelling is switched off. You can hold the measuring tool freely in your hand or place it on a sloping surface. This means that the laser beams are no longer levelled and no longer necessarily run perpendicular to one an- other. Accuracy Check of the Measuring Tool 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 re- commended that you use the measuring tool on a tripod. In addition, position the meas- uring 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 be- fore beginning work. First check the height accuracy and levelling accuracy of the horizontal laser line, then the levelling accuracy of the vertical laser line. Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service. Checking the Height Accuracy of the Horizontal Line For this check, you will need a free measuring distance of 5m on firm ground between two walls (designated A andB). – Mount the measuring tool close to wallA on the holder or a tripod, or place it on a firm, level surface. Switch on the measuring tool with the automatic levelling function en- abled and select cross-line mode. Bosch Power Tools 1 609 92A 7AN | (14.12.2021)30 | English

5 m – Aim the laser at the closer wall A and al- low the measuring tool to level in. Mark the middle of the point at which the laser lines cross on the wall (pointI).

180° – Turn the measuring tool 180°, allow it to level in and mark the point where the laser lines cross on the opposite wall B (pointⅡ). – Position the measuring tool –without rotating it– close to wallB, switch it on and al- low it to level in.

– Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the point where the laser lines cross exactly hits the previously marked pointⅡ on wallB.

– Turn the measuring tool 180° without adjusting the height. Aim it at wallA such that the vertical laser line runs through the already marked pointⅠ. Al- low the measuring tool to level in and mark the point where the laser lines cross on wallA (pointⅢ). – The discrepancy d between the two marked pointsⅠ and Ⅲ on wallA reveals the ac- tual height deviation of the measuring tool. 1 609 92A 7AN | (14.12.2021) Bosch Power ToolsEnglish | 31 The maximum permitted deviation on the measuring distance of 2×5m=10m is as fol- lows: 10m×±0.3mm/m=±3mm. The discrepancy d between pointsⅠ and Ⅲ must therefore amount to no more than 3mm. Checking the Level Accuracy of the Horizontal Line For this check, you will need a free area of 5×5m. – Mount the measuring tool in the middle between wallsA and B on the holder or a tri- pod, or place it on a firm, flat surface. Switch on the measuring tool with the auto- matic levelling function enabled and select horizontal mode. Allow the measuring tool to level in. 2,5 m 5,0 m 5,0 m 5,0 m 5,0 m

– At a distance of 2.5m from the measur- ing tool, mark the centre of the laser line on both walls (pointⅠ on wallA and pointⅡ on wallB). 2,5 m

– Set up the measuring tool at a 5m dis- tance and rotated by 180° and allow it to level in. – Align the height of the measuring tool (using the tripod or by placing objects under- neath as required) so that the centre of the laser line exactly hits the previously marked pointⅡ on wallB. – Mark the centre of the laser line on wallA as pointⅢ (vertically above or below pointⅠ). Bosch Power Tools 1 609 92A 7AN | (14.12.2021)32 | English – The discrepancy d between the two marked pointsⅠ and Ⅲ on wallA reveals the ac- tual horizontal deviation of the measuring tool. The maximum permitted deviation on the measuring distance of 2×5m=10m is as fol- lows: 10m×±0.3mm/m=±3mm. The discrepancy d between pointsⅠ and Ⅲ must therefore amount to no more than 3mm. Checking the Level Accuracy of the Vertical Line For this check, you will need a door opening (on solid ground) which has at least 2.5m of space either side of the door. – Place the measuring tool 2.5m away from the door opening on a firm, flat surface (not on a tripod). Switch on the measuring tool in the mode with automatic levelling. Se- lect vertical mode and allow the measuring tool to level in. 2,5 m 2,5 m – Mark the centre of the vertical laser line on the floor of the door opening (pointⅠ), 5m away on the other side of the door opening (pointⅡ) and on the upper edge of the door opening (pointⅢ). 2 m
