Bosch Power Tools 1 619 929 J22 | (27.6.11) charger to the mains supply. Charging the empty battery pack takes approx. 14 h. The battery charger and the battery 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 charg- ing/discharging cycles. Do not charge the battery pack 7 each time after using, other- wise its capacity will be reduced. Charge the battery pack on- ly when the charge-control indicator 6 flashes or lights up continuously. A considerably reduced operating period after charging indi- cates 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 15 when connected to a power supply. Switch the measuring tool off, charge the bat- tery pack for approx. 10 min and then switch the measuring tool on again with the battery charger connected. To change the battery pack 7, turn the locking knob 10 to position and pull out the battery pack 7. Insert a new battery pack and turn the locking knob 10 to the position. f Remove the battery pack from the measuring tool when not using it for longer periods. When storing for longer periods, the rechargeable batteries can corrode and discharge themselves. Charge-control Indicator When the charge-control indicator 6 flashes red for the first time, the measuring tool can still be operated for approx. 2 h. When the charge-control indicator 6 lights up red continuous- ly, measurements are no longer possible. The measuring tool switches off automatically after 1 minute. Power Supply of the Laser Receiver Alkali-manganese batteries are recommended for the laser receiver. Press the latch 18 of the battery lid outward and open the bat- tery lid 28. When inserting the battery, pay attention to the correct polar- ity according to the representation on the inside of the battery compartment. When the battery low indicator b appears for the first time on the display 25, the laser receiver can still be operated for ap- prox. 3 h. f Remove the battery from the laser receiver when not using it for longer periods. When storing for longer peri- ods, the battery can corrode and discharge itself. Operation Starting Operation of the Rotational Laser Level f Protect the measuring tool against moisture and direct sun light. f Do not subject the measuring tool to extreme tempera- tures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large varia- tions in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired. f Avoid heavy impact to or dropping down of the measur- ing 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 21) each time before continuing to work. Setting Up the Measuring Tool Position the measuring tool on a firm sur- face or mount it to a tripod 30. Due to the high levelling accuracy, the measuring tool reacts sensitively to ground vibrations and position changes. Therefore, pay attention that the position of the meas- uring tool is stable in order to avoid opera- tional interruptions due to re-levelling. Switching On and Off f Do not direct the laser beam at persons or animals (es- pecially not at their eye level), and do not stare into the laser beam yourself (not even from a distance.) Imme- diately after switching on, the measuring tool sends out the variable laser beam 4. For switching on the measuring tool, briefly press the On/Off button 2. The indicators 3, 1 and 6 light up briefly. The meas- uring tool immediately starts the automatic levelling. During the levelling, the levelling indicator 1 flashes green, the laser does not rotate and flashes. The measuring tool is levelled in as soon as levelling indicator 1 lights up green continuously and the laser beam is steady. After the levelling is completed, the measuring tool automati- cally starts in rotational operation. The measuring tool exclusively operates with fixed rotational speed in rotational operation, which is also suitable for use of a laser receiver. When factory set, the shock-warning function is automatically switched on, and the shock-warning indicator 3 lights up green. To switch off the measuring tool, briefly press the On/Off button 2. When the shock warning has actuated (shock-warn- ing indicator 3 flashes red), briefly press the On/Off button once to restart the shock-warning function, and then again to switch off the measuring tool. f Do not leave the switched on measuring tool unattend- ed and switch the measuring tool off after use. Other persons could be blinded by the laser beam. To save the batteries, the measuring tool is automatically 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 20). Reposition the measuring tool and switch it on again. Starting Operation of the Laser Receiver f Protect the laser receiver against moisture and direct sun light.

1 619 929 J22 | (27.6.11) Bosch Power Tools f Do not subject the laser receiver to extreme tempera- tures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large varia- tions in temperature, allow the laser receiver to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the laser receiver can be impaired. Position the laser receiver at least 50 cm away from the rota- tional laser level. Position the laser receiver in such a manner that the laser beam can reach the reception area 24. Switching On and Off f A loud audio signal sounds when switching on the laser receiver. “The A-weighted sound pressure level of the au- dio signal is up to 95 dB(A) at a distance of 0.2 m.” f Do not hold the laser receiver close to your ear! The loud audio signal can cause hearing defects. To switch on the laser receiver, press the On/Off button 19. Two audio signals sound and all display indicators light up briefly. To switch off the laser receiver, press the On/Off button 19 again. When no button is pressed on the laser receiver for approx. 10 minutes and when no laser beam reaches the reception ar- ea 24 for 10 minutes, the laser receiver automatically switch- es off in order to save the battery. The switching off is indicat- ed by an audio signal. Selecting the Setting of the Centre Indicator With button 20, you can specify with which accuracy the po- sition of the laser beam is indicated as central on the recep- tion area: – “Fine” adjustment, (indication f on the display), – “Medium” adjustment, (indication a on the display). An audio signal sounds when the accuracy setting 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 receiver) indicate the position of the rotating laser beam in the reception area 24. Additionally, the position can be indicated with an audio signal (see “Audio Sig- nal for Indication of the Laser Beam”, page 20). Laser receiver too low: When the laser beam runs through the top half of the reception area 24, the bottom direction in- dicator 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 23, only the tip of the di- rection indicator g is indicated. Laser receiver too high: When the laser beam runs through the bottom half of the reception area 24, the top direction in- dicator c appears on the display. When the audio signal is switched on, a fast-beat signal sounds. Move the laser receiver downward in the direction of the ar- row. When approaching the centre mark 23, only the tip of the direction indicator c is indicated. Laser receiver in centre position: When the laser beam runs through the reception area 24 at the centre mark 23, the cen- tre indicator e lights up. When the audio signal is switched on, a continuous signal sounds. Audio Signal for Indication of the Laser Beam The position of the laser beam on the reception area 24 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 volume level, push the acoustic signal button 21 until the requested volume level is indicated. At medium volume level, the audio signal indica- tor d in the display flashes; at high volume level, the indicator is continuously lit. When the audio signal is set to off, the indi- cator goes out. Automatic Levelling of the Rotational Laser Level After switching on, the measuring tool checks the horizontal position and automatically compensates irregularities within the self-levelling range of approx. 8 % (5°). When the measuring tool is inclined by more than 8 % after switching on or after a position change, levelling in is no long- er possible. In this case, the rotor is stopped, the laser flashes and levelling indicator 1 continuously lights up red. Reposi- tion the measuring tool and wait for it to re-level. Without re- positioning, the laser is automatically switched off after 2 minutes and the measuring tool after 2 hours. When the measuring tool is levelled in, it continuously checks the horizontal position. Automatic re-levelling takes place af- ter position changes. To avoid faulty measurements, the rotor stops during the levelling process, the laser flashes and the levelling indicator 1 flashes green. 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 heights, and thus prevents vertical errors. When factory set, the shock-warning function is activated af- ter switching on the measuring tool (shock-warning indicator 3 lit). The shock warning is activated approx. 30 s after switching on the measuring tool or switching on the shock- warning function. 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 1 goes out and the shock-warning indicator 3 flashes red. When the shock-warning function has actuated, briefly press the On/Off button 2. The shock-warning function is restarted and the measuring tool starts the levelling. As soon as the measuring tool is levelled in (the levelling indicator 1 continu- ously lights up green), it automatically starts in rotation oper- ation. Now, check the height of the laser beam with a refer- ence point and correct the height, if required. OBJ_DOKU-20994-002.fm Page 20 Monday, June 27, 2011 12:55 PM

Bosch Power Tools 1 619 929 J22 | (27.6.11) When, after the shock-warning function has actuated, the function is not restarted by pressing On/Off button 2, the la- ser is automatically switched off after 2 minutes and the measuring tool after 2 hours. To switch off the shock-warning function, press the On/Off button 2 for 3 seconds. When the shock-warning function has actuated (shock-warning indicator 3 flashes red), firstly press the On/Off button briefly, and then again for 3 seconds. When the shock-warning function is shut off, the shock-warning in- dicator goes out 3. To switch on the shock-warning function, press the On/Off button 2 for 3 seconds. The shock-warning indicator 3 contin- uously lights up green, and the shock-warning function is acti- vated after 30 seconds. The shock-warning function setting is stored when switching off the measuring tool. Levelling Accuracy of the Rotational Laser Level Influences on Accuracy The ambient temperature has the greatest influence. Espe- cially temperature differences occurring from the ground up- ward can divert the laser beam. The deviations play a role in excess of approx. 20 m measur- ing distance and can easily reach two to four times the devia- tion 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 pos- sible, 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 before starting your work. A free measuring distance of 20 m on a firm surface between two walls A and B is required for the check. A reversal meas- urement must be carried out over both axes X and Y (each positive and negative; 4 complete measurements). – Mount the measuring tool onto a tripod, or place it on a firm and level surface close to wall A. Switch the measuring tool on. – After the levelling, mark the centre of the laser beam on wall A (point I). – Rotate the measuring tool by 180°, allow it to level in and mark the centre point of the laser beam on the apposing 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 propping), so that the centre of the laser beam runs ex- actly 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 proce- dure by 90°. On the measuring section of 2 x 20 m = 40 m, the maximum allowable deviation is: 40 m x ±0.08 mm/m = ±3.2 mm. Consequently, the difference d between points I and III for each of the four individual measurements may not exceed 3.2 mm max.

1 619 929 J22 | (27.6.11) Bosch Power Tools If the measuring tool should exceed the maximum 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 line for marking. The width of the laser line 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 appear brighter for the eyes. f Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisa- tion 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 glasses do not afford complete UV protection and reduce colour perception. Working with the Tripod (Accessory) The measuring tool is equipped with a 5/8" tripod mount for horizontal operation on a tripod. Place the measuring tool via the tripod mount 12 onto the 5/8" male thread of the tripod and screw the locking screw of the tripod tight. On a tripod 30 with a measuring scale on the elevator column, the height difference can be adjusted directly. Working with the Laser Target Plate (Accessory) Using the laser target plate 37, it is possible to transmit the la- ser height onto a wall. With the zero field and the scale, the offset or drop to the re- quired height can be measured and projected at another loca- tion. This eliminates the necessity of precisely adjusting the measuring tool to the height to be projected. The laser target plate 37 has a reflecting coating which im- proves the visibility of the laser beam from a larger distance or in case of strong sun rays. The luminosity can be recognized only if you look to the laser target plate in parallel to the laser beam. Working with the Measuring Rod (Accessory) For checking irregularities or projecting gradients, it is recom- mended to use the measuring rod 31 together with the laser receiver. A relative millimeter scale (±50 cm) is marked on the top of the measuring rod 31. Its zero height can be preset at the bot- tom of the elevator column. This allows for direct reading of deviations from the specified height. Working Instructions for the Laser Receiver Marking When the laser beam runs through the center of the reception area 24, its height can be marked at the centre mark 23 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 26. A laser receiver attached out-of-level leads to faulty measurements. Attaching with the Holder (see figure A) With the holder 35, the laser receiver can be fastened to a construction laser measuring rod 31 (accessory) as well as to other auxiliary tools with a width of up to 65 mm. Screw the holder 35 to the retainer opening 29 on the rear side of the measuring tool with fastening screw 34. Loosen the locking screw 32, slide the holder onto the con- struction laser measuring rod 31, for example, and retighten the locking screw 32. The upper edge 33 of the holder is located at the same height as the centre mark 23 and can be used for marking of the laser beam. Attaching with the Magnet (see figure B) When a positive-lock attachment is not absolutely required, the laser receiver can be attached to steel parts via the face side using the magnet plate 22. Work Examples Checking the Depth of Building Pits (see figure C) Position the measuring tool on a firm surface or mount it to a tripod 30. 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 be- tween the laser beam and the height at the reference point with the laser target plate 37. Project or check the measured height difference at the target location. When measuring over long distances, the measuring tool should always be set up in the centre of the work surface and on a tripod, in order to reduce interferences. When working on unsafe ground, mount the measuring tool onto the tripod 30. Take care that the shock-warning function is activated, in order to avoid faulty measurements in case of ground vibrations or shock to the measuring tool.
