Robert Bosch GmbH, Power Tools Division D-70745 Leinfelden-Echterdingen Leinfelden, 31.10.2008 Assembly Power Supply of the Rotational Laser Level Operation with Batteries/Rechargeable Batteries Use only alkali-manganese or rechargeable batteries. To open the battery compartment 14, turn the locking knob 15 to position and pull out the battery compartment. When inserting batteries, pay attention to the correct polarity according to the representation on the inside of the battery compartment. Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity. Shut the battery compartment 14 and turn the locking knob 15 to the position. In case the batteries have been inserted incor- rectly, the measuring tool cannot be switched on. Insert the batteries with correct polarity. f Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the bat- teries can corrode and discharge themselves. Operation with Battery Pack Charge the battery pack 13 before using for the first time. The battery pack can only be charged with the battery charger 21 intended for it. f Observe the mains voltage! The voltage of the power supply must correspond with the data given on the nameplate of the battery charger. Battery chargers marked with 230 V can also be operated with 220 V. Insert the appropriate mains plug 22 for your mains supply into the battery charger 21 and allow it to engage. Insert the charge plug 23 of the battery charger into the socket connector 17 of the battery pack. Connect the battery charger to the mains supply. Charging the empty battery pack takes approx. 14 h. The battery charger and the bat- tery pack are protected against overcharging. A battery that is new or has not been used for a longer period does not develop its full capacity until after approx. 5 charging/discharging cycles. Dr. Egbert Schneider Senior Vice President Engineering Dr. Eckerhard Strötgen Head of Product Certification OBJ_BUCH-757-004.book Page 29 Wednesday, December 10, 2008 4:25 PM30 | English 1 609 929 R48 | (10.12.08) Bosch Power Tools Do not charge the battery pack 13 each time after using, otherwise its capacity will be re- duced. Charge the battery pack only when the charge-control indicator 12 flashes or lights up continuously. A considerably reduced operating period after charging indicates that the battery pack is used up and must be replaced. If the battery pack is empty, the measuring tool can also be operated off of the battery charger 21 when connected to a power supply. Switch the measuring tool off, charge the battery pack for approx. 10 min and then switch the measuring tool on again with the battery charger connected. To change the battery pack 13, turn the locking knob 16 to position and pull out the battery pack 13. Insert a new battery pack and turn the locking knob 16 to the position. f Remove the battery pack from the measur- ing tool when not using it for longer peri- ods. When storing for longer periods, the rechargeable batteries can corrode and dis- charge themselves. Charge-control Indicator When the charge-control indicator 12 flashes red for the first time, the measuring tool can still be operated for approx. 2 h. When the charge-control indicator 12 lights up red continuously, measurements are no longer possible. The measuring tool switches off auto- matically after 1 minute. Power Supply of the Laser Receiver Use only alkali-manganese batteries. Press the latch 24 of the battery lid outward and open the battery lid 34. When inserting the battery, pay attention to the correct polarity according to the representation on the inside of the battery compartment. When the battery indication b appears for the first time on the display 32, the laser receiver can still be operated for approx. 3 h. f Remove the battery from the laser receiver when not using it for longer periods. When storing for longer periods, the battery can corrode and discharge itself. Operation Starting Operation of the Rotational Laser Level f Avoid heavy impact to or falling down of the measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out an accuracy check (see “Levelling Accuracy of the Rotational Laser Level”, page 33) each time before continuing to work. f Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the measuring tool to ad- just to the ambient temperature before putting it into operation. In case of extreme tempera- tures or variations in temperature, the accura- cy of the measuring tool can be impaired. Setting Up the Measuring Tool Position the measuring tool on a firm surface in the horizontal or vertical position, mount it to a tripod 48 or to the wall mount 43. Due to the high levelling accuracy, the measur- ing tool reacts sensitively to ground vibrations and position changes. Therefore, pay attention that the position of the measuring tool is stable in order to avoid operational interruptions due to re-levelling. Switching On and Off f Do not direct the laser beam at persons or animals (especially not at their eye level), and do not stare into the laser beam your- self (not even from a distance). Immediately after switching on, the measuring tool sends out the vertical plumb beam 9 and the varia- ble laser beam 6. For switching on the measuring tool, press the On/Off button 4. The indicators 1, 3 and 12 light up briefly. The measuring tool immediately Horizontal position Vertical position OBJ_BUCH-757-004.book Page 30 Wednesday, December 10, 2008 4:25 PMEnglish | 31 Bosch Power Tools 1 609 929 R48 | (10.12.08) starts the automatic levelling. During the level- ling, the levelling indicator 3 lights up green and the laser flashes in point operation. The measuring tool is levelled in as soon as level- ling indicator 3 lights up green continuously and the laser beam is steady. After the levelling is completed, the measuring tool automatically starts in rotational operation. With the operating mode buttons 5 and 11, the operating modes can already be specified during levelling in (see “Operating Modes of the Rota- tional Laser Level”, page 31). In this case, the measuring tool starts in the set operating mode upon completion of levelling in. To switch off the measuring tool, press the On/Off button 4 again. To save the batteries, the measuring tool is auto- matically switched off when not within the self- levelling range for more than 2 h or when the shock warning is actuated for more than 2 h (see “Automatic Levelling of the Rotational Laser Level”, page 33). Reposition the measuring tool and switch it on again. Operating Modes of the Rotational Laser Level Overview All three operating modes are possible with the measuring tool in horizontal and vertical position. Rotational Operation Rotational operation is especial- ly recommended when using the laser receiver. You can select be- tween different rotational speeds. Line Operation In this operation mode, the vari- able laser beam moves within a limited aperture angle. This in- creases the visibility of the laser beam in comparison to rotation- al operation. You can select be- tween different aperture angles. Point Operation This operation mode enables the best visibility of the variable laser beam. As an example, it is used for easy projecting of heights or checking building lines. Rotational Operation (150/300/600 min

Each time after switching on, the measuring tool is in rotational operation mode with average ro- tational speed. To switch from line operation to rotational oper- ation, press the rotational operation button 5. Rotational operation starts with average rota- tional speed. To change the rotational speed, press the rota- tional operation button 5 again until the re- quested speed is reached. When working with the laser receiver, the high- est rotational speed should be set. When work- ing without laser receiver, reduce the rotational speed for improved visibility of the laser beam and use the laser viewing glasses 42. Line Operation, Point Operation (10°/25°/35°, 0°) To switch to line or point operation, press the line operation button 11. The measuring tool switches to line operation with the smallest aperture angle. To change the aperture angle, press the line operation button 11. The aperture angle is in- creased in two steps; at the same time, the rotational speed is increased with each step. When pressing the line operation button 11 a third time, the measuring tool switches to point operation after brief post-pulsation. Pressing button 11 again takes you back to line operation with the smallest aperture angle. Note: Due to inertia, it is possible for the laser to slightly move beyond the end point of the laser line. To position the laser line or the laser point with- in the rotational plane, manually turn the rota- tion head 10 to the requested position or use the remote control 46. Turning the Rotational Plane when in the Vertical Position When the measuring tool is in the vertical posi- tion, it is possible to rotate the laser point, laser line or rotational plane around the vertical axis with help of the remote control 46. For this, ob- serve the operating instructions of the remote control. OBJ_BUCH-757-004.book Page 31 Wednesday, December 10, 2008 4:25 PM32 | English 1 609 929 R48 | (10.12.08) Bosch Power Tools Starting Operation of the Laser Receiver f Protect the laser receiver against moisture. f Do not subject the laser receiver to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the laser receiver to adjust to the ambient temperature before putting it into operation. In case of extreme tempera- tures or variations in temperature, the accura- cy of the laser receiver can be impaired. Position the laser receiver at least 50 cm away from the rotational laser level. Position the laser receiver in such a manner that the laser beam can reach the reception area 31. Set the highest rotational speed on the rotational laser level. Switching On and Off f A loud audio signal sounds when switching on the measuring tool. Therefore, keep the laser receiver away from your ear or other persons when switching on. The loud audio signal can cause hearing defects. To switch on the laser receiver, press the On/ Off button 26. Two audio signals sound and all display indicators light up briefly. To switch off the laser receiver, press the On/Off button 26 again. When no button is pressed on the laser receiver for approx. 10 minutes and when no laser beam reaches the reception area 31 for 10 minutes, the laser receiver automatically switches off in order to save the battery. The switching off is indicated by an audio signal. Selecting the Setting of the Centre Indicator With button 27, you can specify with which ac- curacy the position of the laser beam is indicat- ed as central on the reception area: – “Fine” adjustment, (indication f on the dis- play), – “Medium” adjustment, (indication a on the display). An audio signal sounds when the accuracy set- ting is changed. Whenever switching on the laser receiver, the accuracy level “medium” is set. Direction Indicators The bottom g, centre e and top c indicators (both on the front and rear side of the laser re- ceiver) indicate the position of the rotating laser beam in the reception area 31. Additionally, the position can be indicated with an audio signal (see “Audio Signal for Indication of the Laser Beam”, page 32). Laser receiver too low: When the laser beam runs through the top half of the reception area 31, the bottom direction indicator g appears on the display. When the audio signal is switched on, a slow- beat signal sounds. Move the laser receiver upward in the direction of the arrow. When approaching the centre mark 30, only the tip of the direction indicator g is indicated. Laser receiver too high: When the laser beam runs through the bottom half of the reception area 31, the top direction indicator c appears on the display. When the audio signal is switched on, a fast- beat signal sounds. Move the laser receiver downward in the direc- tion of the arrow. When approaching the centre mark 30, only the tip of the direction indicator c is indicated. Laser receiver in centre position: When the la- ser beam runs through the reception area 31 at the centre mark 30, the centre indicator e lights up. When the audio signal is switched on, a con- tinuous signal sounds. Audio Signal for Indication of the Laser Beam The position of the laser beam on the reception area 31 can be indicated via an audio signal. After the laser receiver has been switched on, the audio signal is always switched off. When switching on the audio signal, you can choose between two volume levels. To switch on the audio signal or change the vol- ume level, push the acoustic signal button 28 until the requested volume level is indicated. At medium volume level, the audio signal indicator d in the display flashes; at high volume level, the indicator is continuously lit. When the audio sig- nal is set to off, the indicator goes out. OBJ_BUCH-757-004.book Page 32 Wednesday, December 10, 2008 4:25 PMEnglish | 33 Bosch Power Tools 1 609 929 R48 | (10.12.08) Automatic Levelling of the Rotational Laser Level Overview After switching on, the measuring tool automat- ically detects the horizontal or vertical position. To change between the horizontal and vertical position, switch the measuring tool off, reposi- tion it and switch on again. After switching on, the measuring tool checks the horizontal and vertical position and automatically levels out any unevenness within the self-level- ling range of approx. 8 % (±0.8 m/10 m). When the measuring tool is inclined by more than 8 % after switching on or after a position change, levelling in is no longer possible. In this case, the rotor is stopped, the laser flashes and levelling indicator 3 continuously lights up red. Reposition the measuring tool and wait for it to re-level. Without repositioning, the laser is auto- matically switched off after 2 minutes and the measuring tool after 2 hours. When the measuring tool is levelled in, it continu- ously checks the horizontal and vertical position. Automatic re-levelling takes place after position changes. To avoid faulty measurements, the rotor stops during the levelling process, the laser flash- es and the levelling indicator 3 flashes green. Schock-warning Function The measuring tool has a shock-warning function; after position changes or shock to the measuring tool, or in case of ground vibrations, it keeps the measuring tool from levelling in at changed heights, and thus prevents vertical errors. To switch on the shock-warning function, press the shock-warning button 2. The shock-warning indicator 1 continuously lights up green, and the shock-warning function is activated after 30 sec- onds. When the levelling-accuracy range is exceeded after a position change of the measuring tool or when heavy ground vibrations are detected, the shock-warning function is actuated: The rota- tion is stopped, the laser flashes, the levelling indicator 3 goes out and the shock-warning indi- cator 1 flashes red. The current operating mode is stored. After the shock-warning function has actuated, press the shock-warning button 2. The shock- warning function is restarted and the measuring tool starts the levelling. As soon as the measur- ing tool is levelled in (levelling indicator 3 con- tinuously lights up green), it starts in the stored operating mode. Now, check the height of the laser beam with a reference point and correct the height, if required. When the function is not restarted by pressing button 2 after the shock-warning function has actuated, the laser is automatically switched off after 2 minutes and the measuring tool after 2hours. To switch off the shock-warning function, press shock-warning button 2 once, or, when the shock warning is actuated (shock-warning indi- cator 1 flashing red) press it twice. When the shock-warning function is shut off, the shock- warning indicator 1 goes out. Levelling Accuracy of the Rotational Laser Level Influences on Accuracy The ambient temperature has the greatest influ- ence. Especially temperature differences occur- ring from the ground upward can divert the laser beam. The deviations play a role in excess of approx. 20 m measuring distance and can easily reach two to four times the deviation at 100 m. Because the largest difference in temperature layers is close to the ground, the measuring tool should always be mounted on a tripod when measuring distances exceeding 20 m. If possi- ble, also set up the measuring tool in the centre of the work area. Accuracy Check of the Measuring Tool Apart from exterior influences, device-specific influences (such as heavy impact or falling down) can lead to deviations. Therefore, check the accuracy of the measuring tool each time be- fore starting your work. For the accuracy check, an unobstructed meas- uring distance of 20 m on firm ground between two walls A and B is required. With the measur- ing tool in the horizontal position, a transit OBJ_BUCH-757-004.book Page 33 Wednesday, December 10, 2008 4:25 PM34 | English 1 609 929 R48 | (10.12.08) Bosch Power Tools measurement is to be carried out across both axes X and Y (both positive and negative) (alto- gether 4 complete measurements). – Mount the measuring tool in the horizontal po- sition onto a tripod 48 (accessory) or place it on a firm and level surface near wall A. Switch the measuring tool on. – After levelling, direct the laser beam in point operation onto the close wall A. Mark the centre point of the laser beam on the wall (point I). – Turn the measuring tool around by 180°, allow it to level in and mark the centre point of the laser beam on the opposite wall B (point II). – Without turning the measuring tool, position it close to wall B. Switch the measuring tool on and allow it to level in. – Align the height of the measuring tool (using the tripod or by underlaying, if required) in such a manner that the centre point of the laser beam is projected exactly against the previously marked point II on wall B. – Rotate the measuring tool by 180° without changing the height. Allow it to level in and mark the centre point of the laser beam on wall A (point III). Take care that point III is as vertical as possible above or below point I. – The difference d of both marked points I and III on wall A amounts to the actual deviation of the measuring tool for the measured axis. Repeat the measuring procedure for the other three axes. For this, turn the measuring tool prior to each measuring procedure by 90°. On the measuring section of 2 x 20 m = 40 m, the maximum allowable deviation is: 40 m x ± 0.1 mm/m = ± 4mm. Consequently, the difference d between points I and III for each of the four individual measure- ments may not exceed 4 mm max. If the measuring tool should exceed the maxi- mum deviation in anyone of the four measuring procedures, have it checked at a Bosch after- sales service agent. Working Instructions for the Rotational Laser Level f Always use the centre of the laser point for marking. The size of the laser point changes with the distance. Laser Viewing Glasses (Accessory) The laser viewing glasses filter out the ambient light. This makes the red light of the laser ap- pear brighter for the eyes.

180˚ OBJ_BUCH-757-004.book Page 34 Wednesday, December 10, 2008 4:25 PMEnglish | 35 Bosch Power Tools 1 609 929 R48 | (10.12.08) f Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. f Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glass- es do not afford complete UV protection and reduce colour perception. Working with the Remote Control (Accessory) While pressing the operator buttons, the meas- uring tool can be brought out of alignment so that the rotation is briefly stopped. This effect is avoided when using the remote control 46. Reception lenses 7 for the remote control are located on three sides of the measuring tool, among other locations above the control panel on the front side. Working with the Tripod (Accessory) The measuring tool is equipped with a 5/8" tri- pod mount for horizontal operation on a tripod. Place the measuring tool via the tripod mount 18 onto the 5/8" male thread of the tripod and screw the locking screw of the tripod tight. On a tripod 48 with a measuring scale on the elevator column, the height difference can be adjusted directly. Working with the Wall Mount (Accessory) (see figure C) The measuring tool can also be fastened to the wall mount 43. In horizontal operation, the wall mount allows for usage of the measuring tool at any height. In vertical operation, the measuring tool can be fastened to a 5/8" tripod 48. Working with the Ceiling Measurement Plate (see figure C) As an example, the ceiling measurement plate 45 can be used for easy height adjustment of drop ceilings. Fasten the ceiling measurement plate with the magnetic holder, e.g., to a beam. The reflecting half of the ceiling measurement plate improves the visibility of the laser beam in unfavourable conditions; the laser beam can also be seen from the rear side through the transpar- ent half. Working with the Measuring Plate (Accessory) With the measuring plate 44, it is possible to project the laser mark onto the floor or the laser height onto a wall. With the zero field and the scale, the offset or drop to the required height can be measured and projected at another location. This elimi- nates the necessity of precisely adjusting the measuring tool to the height to be projected. The measuring plate 44 has a reflective coating that enhances the visibility of the laser beam at greater distances or in intense sunlight. The brightness intensification can be seen only when viewing, parallel to the laser beam, onto the measuring plate. Working with the Measuring Rod (Accessory) (see figure J) For checking irregularities or projecting gradi- ents, it is recommended to use the measuring rod 38 together with the laser receiver. A relative millimeter scale (±50 cm) is marked on the top of the measuring rod 38. Its zero height (90 to 210 cm) can be preset at the bottom of the elevator column. This allows for direct read- ing of deviations from the specified height. 30 mm OBJ_BUCH-757-004.book Page 35 Wednesday, December 10, 2008 4:25 PM36 | English 1 609 929 R48 | (10.12.08) Bosch Power Tools Working Instructions for the Laser Receiver Marking When the laser beam runs through the center of the reception area 31, its height can be marked at the centre mark 30 right and left on the laser receiver. The centre mark is located 45 mm away from the top edge of the laser receiver. Aligning with the Spirit Level The laser receiver can be aligned vertically (plumb line) with the spirit level 25. A laser receiver attached out-of-level leads to faulty measurements. Attaching with the Holder (see figure A) With the holder 40, the laser receiver can be fas- tened to a construction laser measuring rod 38 (accessory) as well as to other auxiliary tools with a width of up to 65 mm. Screw the holder 40 to the retainer opening 33 on the rear side of the measuring tool with fas- tening screw 39. Loosen the locking screw 36, slide the holder onto the construction laser measuring rod 38, for example, and retighten the locking screw 36. The holder 40 can be horizontally aligned with help of the spirit level 41. The upper edge 37 of the holder is located at the same height as the centre mark 30 and can be used for marking of the laser beam. Attaching with the Magnet (see figure B) When a positive-lock attachment is not absolute- ly required, the laser receiver can be attached to steel parts via the face side using the magnet plate 29. Work Examples Projecting/Checking Heights (see figure D) Position the measuring tool in the horizontal position onto a firm support or mount it onto a tripod 48 (accessory). Working with tripod: Align the laser beam to the requested height. Project or check the height at the target location. Working without tripod: Determine the height difference between the laser beam and the height at the reference point with help of the measurment plate 44. Project or check the meas- ured height difference at the target location. Parallel Alignment of a Plumb Beam/ Projecting Right Angles (see figure E) When right angles are to be projected or when partitions are to be aligned, the plumb beam 9 must be aligned 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 plumb beam runs approximately parallel to the reference line. For exact positioning, measure the clearance between plumb beam and reference line direct- ly on the measuring tool with help of the meas- urment plate 44. Measure the clearance be- tween plumb beam and reference line again as far away as possible from the measuring tool. Align the plumb beam 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 plumb beam 9 is indicated by the variable laser beam 6. Indicating a Plumb Line/Vertical Plane (see figure F) To indicate a plumb line 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), then align the plumb beam 9 with this reference line. The plumb line is indicated by the variable laser beam 6.

For better visi- bility of the laser beam, either select line opera- tion, or select point operation and manually ro- tate the rotation head 10 to the target location. Working with the Laser Receiver (see figure H) Under unfavourable light conditions (bright environment, direct sunlight) and for larger dis- tances, use the laser receiver for improved find- ing of the laser beam. When working with the laser receiver, select rotational operation with the highest rotational speed. Measuring Over Long Distances (see figure I) When measuring over long distances, the laser receiver must be used to find the laser beam. In order to reduce interferences, the measuring tool should always be set up in the centre of the work surface and on a tripod. Working Outdoors (see figure J) The laser receiver should always be used when working outdoors. When working on unsafe ground, mount the measuring tool onto the tripod 48. Activate the shock-warning function in order to avoid faulty measurements in case of ground vibrations or shock to the measuring tool.
