Safety Rules Working safely with the measur- ing tool is possible only when the operating and safety information are read completely and the in- structions contained therein are strictly followed. Never make warning labels on the measuring tool unrecognisable. SAVE THESE INSTRUCTIONS. f Caution – The use of other operating or ad- justing equipment or the application of oth- er processing methods than those men- tioned here, can lead to dangerous radiation exposure. f The measuring tool is delivered with two warning labels in German language (marked with the number 16 and 4 in the representa- tion of the measuring tool on the graphic page):

Before putting into operation for the first time, attach the supplied stickers in your na- tional language over the German text on warning label

as well as the complete warning label

with the corresponding la- bels in your national language. The stickers are supplied together with the measuring tool. f Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself. This measuring tool produc- es laser class 3R laser radiation according to EN 60825-1. A direct look into the laser beam, even from a larger distance, can cause damage to the eye. 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. f Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures that the safety of the measuring tool is maintained. f Do not allow children to use the measuring tool without supervision. They could unin- tentionally direct the laser beam toward per- sons or animals and cause damage to their eyes. f Avoid reflection of the laser beam on smooth surfaces such as windows or mir- rors. A reflected laser beam can also cause damage to the eye. f The measuring tool should be operated only by persons that are familiar with the han- dling of laser devices. According to EN 60825-1, this includes, among other things, the knowledge about the bioligical ef- fects of the laser to the eyes and the skin as well as the correct usage of laser protection devices in order to avoid dangers. f Keep the battery charger away from rain or moisture. Penetration of water in the battery charger increases the risk of an electric shock. f Do not charge other batteries with the bat- tery charger. The battery charger is suitable only for charging the Bosch battery pack in- serted in the measuring tool. When charging other batteries, danger of fire and explosion is given.

OBJ_BUCH-78-004.book Page 24 Thursday, July 26, 2007 2:04 PMEnglish | 25 Bosch Power Tools 1 609 929 L80 | (26.7.07) Assembly Charging/Replacing the Battery Pack Charging the Battery Pack Before using for the first time, charge the sup- plied battery pack 15. The battery pack can be charged only when in the measuring tool and on- ly with the battery charger 42 intended for this purpose. Insert the charge connector 41 of the battery charger into the socket 3 and connect the bat- tery charger to the power supply. The red indi- cator on the battery charger lights up during the charge procedure. Charging an empty battery pack requires approx. 7 hours. The charge procedure is ended automatically. Therefore, disconnect the battery charger 42 from the power supply after the charging has taken place. The battery charger 42 and the bat- tery pack 15 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. If the battery pack is empty, the measuring tool can also be operated off of the battery charger 42 when connected to a power supply. Switch the measuring tool off, charge the battery pack for approx. 10 min and then switch the measur- ing tool on again with the battery charger con- nected. Practical Advice on Protection of the Battery Pack Do not recharge the battery pack 15 after each use, as this will reduce its capacity. Recharge the battery pack only when the battery charge control indicator 27 flashes or lights up continu- ously. A considerably reduced operating period after charging indicates that the battery pack is used up and must be replaced. Replacing the Battery Pack The supplied battery pack 15 can also be re- placed against other rechargeable or alkali-man- ganese batteries. Use only batteries or recharge- able batteries of the same brand and with the same capacity. Always replace all of the re- chargeable batteries/batteries together. To remove the battery pack, turn the latch of the battery lid 12 to the position and take off the battery lid 13. Insert either a new battery pack, batteries or other rechargeable batteries. When inserting, pay attention to the correct polarity. As a pro- tective measure against incorrect polarity, the battery pack 15 can be inserted only in one po- sition into the battery compartment. In case other rechargeable batteries/batteries are inserted incorrectly the measuring tool can- not be switched on. Remove and reinsert the other batteries/rechargeable batteries ensuring correct polarity and wait for one minute until switching the measuring tool on again. Reattach the battery lid 13 (only one position possible) and turn the latch 12 to the posi- tion. A fuse ensures that only the battery pack 15 can be charged in the measuring tool. Other re- chargeable batteries cannot be charged in the measuring tool. f Remove the battery pack, other rechargea- ble batteries or batteries from the measur- ing tool when not using it for long periods. When storing for extended periods, re- chargeable batteries/batteries can corrode and discharge themselves. OBJ_BUCH-78-004.book Page 25 Thursday, July 26, 2007 2:04 PM26 | English 1 609 929 L80 | (26.7.07) Bosch Power Tools Operation Initial Operation f Avoid heavy impact or falling of the measur- ing tool. After heavy exterior impact on the measuring tool, an accuracy check should al- ways be carried out before continuing to work (see “Levelling Accuracy”). f Do not subject the measuring tool to ex- treme temperatures or variations in tem- perature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the measur- ing tool to adjust to the ambient temperature before putting it into operation. Setting Up the Measuring Tool Set up the measuring tool on a sturdy surface in the horizontal or vertical position; mount it on a tripod 40 or to the wall holder with alignment unit 32. 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). Immedi- ately after switching on, the measuring tool emits the vertical plumb beam 8 and the var- iable laser beam 9, which rotates around the plumb beam. Special attention with the variable laser beam is required in point oper- ation. To switch on, press the On/Off pushbutton 29. The laser immediately starts in rotational opera- tion, while the automatic levelling begins at the same time (see “Working with Automatic Level- ling”). The indicators 25, 26 and 27 light up for three seconds. During further levelling, the auto- matic levelling indicator “auto” 26 flashes twice per second. When the levelling takes longer than 5 seconds, rotational operation is interrupted and the laser flashes twice per second until lev- elling is completed. With the operating mode pushbuttons 19 and 22 as well as with the direction pushbuttons 20, 21, 23 and 24, the operating mode can already be set upon levelling-in (see “Operating Modes” ). In this case, the measuring tool runs for 5 seconds in the selected operating mode during the levelling to confirm the entry. After the levelling, the function is continued in this operating mode. The measuring tool is levelled-in when the laser beam and the “auto” indicator 26 light up con- tinuously. To switch off, press the On/Off 29 pushbutton again. The measuring tool automatically switches off under the following conditions: – When during automatic levelling, the measur- ing tool is not within the self-levelling range for more than 10 minutes, the device switch- es off to save the batteries. Reposition the measuring tool and switch on again. – When exceeding the maximum permitted op- erating temperature of 50 °C, the measuring tool switches off to protect the laser diode. After cooling down, the measuring tool is ready for operation and can be switched on again. – When the self-check fails or in case of mal- functions during operation, all functions are blocked and the battery charge control indi- cator 27 flickers. – When the measuring tool is not switched on again within 24 hours during activated stand by operation. – When the battery voltage is too low. Horizontal posi- tion Vertical position OBJ_BUCH-78-004.book Page 26 Thursday, July 26, 2007 2:04 PMEnglish | 27 Bosch Power Tools 1 609 929 L80 | (26.7.07) Stand-by-operation with Storage of the Operating Mode The measuring tool can be switched to stand by for a maximum of 24 hours. When the automatic levelling was activated (“auto” indicator 26 lights up continuously) prior to the beginning of the stand by operation, the automatic levelling continues to monitor the position of the measur- ing tool. The operating mode on the measuring tool is retained. To activate stand by operation, press the line operation pushbutton 19 for at least 5 seconds. In stand by, the laser beam and the levelling in- dicators go out; only the battery charge control indicator 27 flashes once every 5 seconds. To switch from stand by operation to normal op- eration, press the line operation pushbutton 19 again for at least 5 seconds. The measuring tool starts in the same operating mode as it was pri- or to the stand by. When the position of the measuring tool is changed as compared to the starting position prior to stand by, the automat- ic levelling reacts as if the out-of-level safety (see “Out-of-level Safety”) were activated: Ei- ther the laser beam can be self-levelled to the same height as before the stand by or the laser beam is switched off as a protective measure against vertical errors. Operating Modes 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 working with the receiver 38. Four differ- ent rotation speeds can be se- lected. Line Operation In this operating mode, the varia- ble laser beam moves within a defined aperture angle. This in- creases the visibility of the laser beam as when compared to rota- tional operation. Four different aperture angles are available. Point Operation In this operating mode, the best visibility of the variable laser beam is achieved. It is used, e.g., for easy projecting of heights or for checking building lines. Course of X- and Y-axis The X- and Y-axis are at a right angle to each oth- er, in accordance with the marks 7 and 6 on the housing. The marks are exactly above the plumb notches 10 (X-axis) and 11 (Y-axis) at the bot- tom edge of the housing. Making Use of the Operating Modes Turning the Rotational Plane in the Vertical Position When the measuring tool is in the vertical posi- tion, the laser point, the laser line or the rota- tional plane can be rotated around the Y-axis for basic sighting out or parallel alignment. For this, press the left 21 or right 24 direction pushbut- ton. Rotation is only possible within the self-levelling range (8 % to the left or right). When the meas- uring tool reaches the limit of this range, a warn- ing signal sounds, the laser and the “man” 25 and “auto” 26 indicators flash once per second. Either press the opposite direction pushbutton (21 or 24), or switch the measuring tool off in order to reposition it. Rotational Operation After switching on, the measuring tool is in rota- tional operation. It starts with the highest rota- tional speed. By pressing the pushbutton for rotational oper- ation 22, the speed can be reduced to a stand- still (point operation) in four steps. Repeated pressing of the pushbutton 22 starts the rota- tional operation again at the highest speed. When working with the receiver 38, it is recom- mended to select the highest rotational speed. When working without the receiver, reduce the rotational speed for improved visibility of the la- ser beam or use the laser viewing glasses 31 (ac- cessory). OBJ_BUCH-78-004.book Page 27 Thursday, July 26, 2007 2:04 PM28 | English 1 609 929 L80 | (26.7.07) Bosch Power Tools When the measuring tool is in the vertical posi- tion and set to automatic levelling, it is possible to rotate the rotational plane around the X-axis by pressing the upper 20 or lower 23 direction push- button. Five seconds after last pressing on either of the four direction pushbuttons, the rotation plane is automatically levelled-in vertical again. Line Operation To switch to line operation, press the pushbutton for line operation 19. Depending on the previous operating mode, the measuring tool switches to point operation or to the line operation with the smallest aperture angle. Repeated pressing of the pushbutton 19 switches the measuring tool via the smallest aperture angle of 4° to the 30°, 60° and 180° aperture angles. At the same time, the speed is increased with each step. When pressing the pushbutton 19 again, the measuring tool returns to point operation. Changing the Aperture Angle: When the meas- uring tool is in the horizontal position and set to automatic levelling, it is possible to increase or reduce the aperture angle by pressing the upper 20 or lower 23 direction pushbutton. The speed remains unchanged. Rotating the Aperture Angle: When the measur- ing tool is in the horizontal position and set to automatic levelling or inclined operation in a sin- gle axis, it is possible to rotate the laser line or the laser point by 360° in steps by pressing the left 21 or right 24 direction pushbuttons. When the measuring tool is in the vertical position and set to automatic levelling, the rotation is ac- tuated by pressing the upper 20 or lower 23 di- rection pushbuttons. Point Operation Point operation can be switched on either by pressing the pushbutton for rotational opera- tion 22 or the pushbutton for line operation 19: – When the measuring tool is set to rotational operation and the pushbutton for line opera- tion 19 is pressed, then the measuring tool starts with point operation. Exception: The measuring tool was already in point opera- tion by having pressed the pushbutton for ro- tational operation 22. In this case, line oper- ation immediately starts with the smallest aperture angle upon pressing the pushbut- ton for line operation. – When the measuring tool is set to line opera- tion and the pushbutton for rotational opera- tion 22 is pressed, then the measuring tool also starts with point operation. Exception: The measuring tool was already in point op- eration by having pressed the pushbutton for line operation 19. In this case, rotational op- eration immediately starts with the highest rotational speed upon pressing the pushbut- ton for rotational operation. Working with Automatic Levelling 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 auto- matically levels out any unevenness within the self-levelling range of approx. 8 %

± 0.8 m/10 m). When the measuring tool, after switching it on or after a position change, is out-of-level by more than 8 %, levelling in is no longer possible. As long as the out-of-level safety was not acti- vated (see “Out-of-level Safety”), a slow-se- quence warning signal sounds, the rotor is stopped, the laser beam and the “auto” 26 as well as the “man” 25 indicators flash once per second. In this case, switch the measuring tool off, realign it and then switch the measuring tool on again. OBJ_BUCH-78-004.book Page 28 Thursday, July 26, 2007 2:04 PMEnglish | 29 Bosch Power Tools 1 609 929 L80 | (26.7.07) Position Changes When the measuring tool is levelled in, it contin- uously checks the horizontal and vertical posi- tion. Position changes of the measuring tool lead to the following reactions: Minor Position Changes Minor position changes are compensated within 5 seconds. The selected operating mode is not interrupted. During the re-levelling, the “auto” indicator 26 flashes twice every second. This au- tomatically compensates ground vibrations at the construction site or weather influences. Major Positon Changes When the measuring tool cannot carry out the levelling-in procedure within 5 seconds, the ro- tor is stopped, the laser beam and the “auto” in- dicator 26 flash twice per second to avoid faulty measurements during the levelling process. Out-of-level Safety The measuring tool has an out-of-level safety feature. It precludes levelling in after height changes exceeding 3 mm/m and thus prevents vertical errors. The out-of-level safety is switched on automatically 30 seconds after a pushbutton is pressed or after a levelling proce- dure. When the out-of-level safety is activated, the “auto” indicator 26 flashes once every 4 sec- onds. After a position change, the measuring tool first attempts to compensate the change. When the limit value 3 mm/m is exceeded upon re-level- ling, a fast-sequence warning signal sounds, the laser switches off and the “man” indicator 25 flashes twice every second. In this case, switch the measuring tool off and then on again. Then, check and correct the height of the laser beam. Working without Automatic Levelling In order to operate the measuring tool in any in- clined position (see “Contouring Gradients”), the automatic levelling can be switched off for the X- and Y-axis. f Position changes of the measuring tool are not detected when the automatic levelling is switched off. Switching Off the Automatic Levelling in the Horizontal Position/Inclined Operation in a Single Axis When the measuring tool is in the horizontal po- sition, the automatic levelling for both axes is switched off by pressing the “man/auto” push- button 28 once. The “man” indicator 25 flashes once per second. Repeated pressing of the “man/auto” pushbut- ton 28 switches on the inclined operation in a single axis. In inclined operation in a single axis, the X-axis is levelled in automatically, but the Y- axis is not. The “man” 25 and “auto” 26 indica- tors flash once per second. When pressing the “man/auto” pushbutton 28 a third time, the automatic levelling is switched on again for both axes. The “auto” indicator 26 flashes (as long as the measuring tool is re-lev- elling) or lights up continuously (when the measuring tool is levelled in). Switching Off the Automatic Levelling in the Vertical Position When the measuring tool is in the vertical posi- tion, the automatic levelling for both axes is switched off by pressing the “man/auto” push- button 28 once. The “man” indicator 25 flashes once per second. Repeated pressing of the “man/auto” pushbut- ton 28 switches the automatic levelling on again. The “auto” indicator 26 flashes (as long as the measuring tool is re-levelling) or lights up continuously (when the measuring tool is lev- elled in). OBJ_BUCH-78-004.book Page 29 Thursday, July 26, 2007 2:04 PM30 | English 1 609 929 L80 | (26.7.07) Bosch Power Tools Changing the Inclination of the Rotational Plane When the automatic levelling is switched off, the rotational plane (as well as the laser point or the laser line) can be rotated around the X- or the Y-axis with the direction pushbuttons. For this, the function of the four direction pushbuttons is independent of the horizontal or vertical position of the measuring tool and of the operating mode. The rotational plane is rotated around the X-axis (directions A and C in the figure) with the upper 20 and lower 23 direction pushbuttons. The left 21 and right 24 direction pushbuttons rotate the rotational plane around the Y-axis (in directions D and B in the figure). In inclined operation in a single axis (horizontal position), the rotational plane can be rotated around the X-axis with the upper 20 and lower 23 direction pushbuttons; rotation around the Y-axis is not possible. Levelling accuracy 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 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 position onto a tripod 40 (accessory) or place it on a firm and level surface near wall A. Switch the measuring tool on.

OBJ_BUCH-78-004.book Page 30 Thursday, July 26, 2007 2:04 PMEnglish | 31 Bosch Power Tools 1 609 929 L80 | (26.7.07) – 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 la- ser beam is projected exactly against the pre- viously marked point II on wall B. – Without altering the height, turn the measur- ing tool around by 180°. Allow the measuring tool to level in and mark the centre point of the laser beam on the wall A (point III). – 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 pri- or to each measuring procedure by 90°. On the measuring distance of 2 x 20 = 40 m, the maximum deviation may not exceed ± 2mm. Consequently, the highest and lowest mark may not be further apart than 4 mm (maximum). 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. Operating Instructions 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. f Do not use the laser viewing glasses as safe- ty goggles. The laser viewing glasses are used for better recognition of the laser beam and thus 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. OBJ_BUCH-78-004.book Page 31 Thursday, July 26, 2007 2:04 PM32 | English 1 609 929 L80 | (26.7.07) Bosch Power Tools Working with the Remote Control While pressing the operator pushbuttons, the measuring tool can be brought out of alignment so that the rotation is briefly stopped. This effect is avoided when using the remote control 39. Receiving areas for the remote control are locat- ed at the laser radiation outlet openings on four sides of the measuring tool as well as next to the socket for the charge plug 3. The reception lens 2 at the bottom edge of the housing reacts to the remote control signals (typical working range: 200 m) with clearly in- creased sensitivity. When using the remote con- trol, set up the measuring tool in such a manner that the signals of the remote control point di- rectly at the reception lens 2. Working with the Tripod (Accessory) The measuring tool is equipped with two 5/8" tripod mounts 17, one for horizontal and one for vertical operation. On a tripod 40 with a measuring scale on the el- evator column, the height difference can be ad- justed directly. Working with Wall Holder/Alignment Unit (Accessory) (see figure A) The measuring tool can also be mounted to the wall holder/alignment unit 32. For this, screw the 5/8" screw 33 of the wall holder into the tri- pod mount 17 for horizontal operation of the measuring tool. Mounting to a wall: Mounting to a wall is recom- mended, e.g., for work above the elevation height of tripods or for work on unstable surfac- es and without tripod. For this, fasten the wall holder 32, with the measuring tool mounted, as vertical as possible to a wall. Mounting on a tripod: The wall holder 32 can al- so be screwed onto a tripod with the tripod mount on the back side. This method of fasten- ing is especially recommended for work where the rotational plane is to be aligned with a refer- ence line. With the alignment unit, it is possible to move the mounted measuring tool vertically (when mount- ed to a wall) or horizontally (when mounted on a tripod) within a range of approx. 10 cm. For this, loosen the knob screws 34 on the alignment unit, move the measuring tool to the required position and tighten the knob screws 34 again. Working with the Measuring Plate With the measuring plate 35, 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 35 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) For checking evenness or projecting gradients, it is recommended to use the measuring rod 30 together with the receiver 38. A relative millimeter scale ( ±50 cm) is marked on the top of the measuring rod 30. 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-78-004.book Page 32 Thursday, July 26, 2007 2:04 PMEnglish | 33 Bosch Power Tools 1 609 929 L80 | (26.7.07) Work Examples Note: For all work examples, with the exception of “Contouring Gradients”, it is assumed that the automatic levelling is switched on. Projecting Height Points (see figure B) Position the measuring tool in the horizontal po- sition onto a firm support or mount it onto a tri- pod 40 (accessory). Working with tripod and receiver 38: In rotation- al operation, align the laser beam to the re- quired height and project the height at the tar- get location. Working without tripod: Using the measuring plate 35, determine the height difference be- tween the laser beam (in point or line opera- tion) and the height line at the reference point. Rotate the laser beam with the left 21 and right 24 direction pushbuttons to the target location and project the measured height difference. Parallel Aligning of a Plumb Beam (see figure C) When right angles are to be projected or when partitions are to be aligned, the plumb beam 8 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 the exact positioning, measure the distance between the plumb beam and the reference line directly at the measuring tool, using the measur- ing plate 35. Now, measure the distance again between the plumb beam and the reference line with the distance as far as possible away from the measuring tool. Using the left 21 and right 24 direction pushbuttons, align the plumb beam in such a manner that it has the same distance to the reference line as measured directly at the measuring tool. Centring a Rotational Plane over a Floor Point (see figure D) When right angles are to be projected from a de- fined floor point, the rotational plane must be centred over this reference point. Set up the measuring tool in the vertical posi- tion as close as possible over the reference point and select point operation. Using the upper 20 and lower 23 direction push- buttons, rotate the variable laser beam in such a manner that it is pointed downward to the floor. With the spirit level 1 at the rotor head, align the laser beam exactly vertical. f Make sure that the variable laser beam is pointed downward before viewing at the spirit level 1 from above. This will avoid looking directly into the laser beam. Position the measuring tool in such a manner that the vertical laser beam precisely meets the reference point. Projecting Right Angles (see figure E) When the measuring tool is in the vertical posi- tion, the right angle is indicated by means of the plumb beam 8 and the variable laser beam 9

If required, centre the rotational plane over a floor point and align the plumb beam 8 parallel to a reference line (e.g. a wall) in order to project right angles. Marking Plumb Lines (see figure F) Set up the measuring tool in the vertical posi- tion and align the variable laser beam 9 to the lo- cation at which the plumb line is to be marked. Select line or rotational operation and mark the plumb line. Marking Vertical Planes (see figure F) Set up the measuring tool in the vertical posi- tion. Bring the variable laser into alignment with a reference line (e.g. a partition). Select line or rotational operation and mark the vertical plane.

For this, position the measuring tool as close as possible to the ref- erence line and select rotational operation. Align the rotational plane approximately parallel to the reference line. For this, rotate the rota- tional plane around the Y-axis using the left 21 and right 24 direction pushbuttons. For easier alignment, the rotational plane can be brought into proximity with the reference line. For this, incline the rotational plane around the X-axis us- ing the upper 20 and lower 23 direction push- buttons. Now, align the rotational plane exactly parallel to the reference line by rotating it around the Y-axis using the left 21 and right 24) direction pushbuttons. When no direction push- button is pressed for 5 seconds, the rotational plane is automatically aligned vertical again. Projecting Plumb Points to the Ceiling The plumb notches 10 and 11 are located at the bottom edge of the housing. They are used for precise alignment of the plumb beam above a floor point. Mark two right-angled auxiliary lines through the floor point. Set up the measuring tool in the horizontal position and bring it into align- ment with the auxiliary lines using the plumb notches. Working with tripod: When the measuring tool is in the horizontal position, the laser origin is locat- ed directly above the horizontal tripod mount. When using a tripod 40 (accessory), a plumb bob can be attached to the tripod fastening screw and used for alignment of the laser to the floor point. Contouring Gradients (see figure H) When contouring gradients, the automatic level- ling must be switched off (see “Working without Automatic Levelling”). Afterwards, the measur- ing tool can be set up in any inclined position. When contouring gradients in only one axis di- rection (e.g. hill flanks or slopes) and when the measuring tool is in the horizontal position, it is recommended to select inclined operation in a single axis – (see “Switching Off the Automatic Levelling in the Horizontal Position/Inclined Op- eration in a Single Axis”). In this case, align the measuring tool with the Y-axis parallel to the di- rection of the incline or slope. For contouring of precise gradients, it is recom- mended to use an inclination gauge 37 (acces- sory) which is mounted onto a tripod 40. It is also possible to align the measuring tool parallel to the required incline by underlaying on one side or with use of the tripod 40 (acces- sory). Within the self-levelling range of 8 %, inclines can also be adjusted with the direction pushbutons.
