Assembly

Power Supply of the Rotational Laser Level

Operation with Batteries/Rechargeable Batteries

Using alkali-manganese or rechargeable batteries is recommended for operation of the measuring tool.

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 incorrectly, the measuring tool cannot be switched on. Insert the batteries with correct polarity.

Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries 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 22 intended for it.

▶ 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 23 for your mains supply into the battery charger 22 and allow it to engage.

Insert the charge plug 24 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 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 charging/discharging cycles.

Do not charge the battery pack 13 each time after using, otherwise its capacity will be reduced. 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 22 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.

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 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 automatically after 1 minute.

Operation

Starting Operation of the Rotational Laser Level

▶ Protect the measuring tool against moisture and direct sun light.
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 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.
- Avoid heavy impact to or dropping 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 30) each time before continuing to work.

Setting Up the Measuring Tool

Horizontal position

Vertical position

Set up the measuring tool on a sturdy surface in the horizontal or vertical position; mount it on a tripod 26 or to the wall mount with alignment unit 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 measuring tool is stable in order to avoid operational interruptions due to re-levelling.

Switching On and Off

Do not direct the laser beam at persons or animals (especially not at their eye level), and do not stare into the laser beam yourself (not even from a distance). Immediately after switching on, the measuring tool sends out the vertical plumb beam 9 and the variable 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 starts the automatic levelling. During the levelling, the levelling indicator 3 lights up green and the laser flashes in point operation.

The measuring tool is levelled in as soon as levelling 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 Rotational Laser Level", page 29). 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.

▶ Do not leave the switched on measuring tool unattended 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 29). 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 especially recommended when using the laser receiver. You can select between different rotational speeds.

Line Operation

In this operation mode, the variable laser beam moves within a limited aperture angle. This increases the visibility of the laser beam in comparison to rotational operation. You can select between 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 ^-1 )

Each time after switching on, the measuring tool is in rotational operation mode with average rotational speed.

To switch from line operation to rotational operation, press the rotational operation button 5. Rotational operation starts with average rotational speed.

To change the rotational speed, press the rotational operation button 5 again until the requested speed is reached.

When working with the laser receiver, the highest rotational speed should be set. When working without laser receiver, reduce the rotational speed for improved visibility of the laser beam and use the laser viewing glasses 29.

Line Operation, Point Operation (10°/25°/50°, 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 increased 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 within the rotational plane, manually turn the rotation head 10 to the requested position or use the remote control 25.

Turning the Rotational Plane when in the Vertical Position

When the measuring tool is in the vertical position, it is possible to rotate the laser point, laser line or rotational plane around the vertical axis with help of the remote control 25. For this, observe the operating instructions of the remote control.

Automatic Levelling of the Rotational Laser Level

Overview

After switching on, the measuring tool automatically detects the horizontal or vertical position. To change between the horizontal and vertical position, switch the measuring tool off, reposition 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-levelling range of approx. 8% (5°).

Pure geometric diagram with crosshair and circular shapes, no text or symbols present

30 | English

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 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 and vertical position. Automatic re-levelling takes place after position changes. To avoid faulty measurements, the rotor stops during the levelling process, the laser flashes and the levelling indicator 3 flashes green.

Shock-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 seconds.

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 rotation is stopped, the laser flashes, the levelling indicator 3 goes out and the shock-warning indicator 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 measuring tool is levelled in (levelling indicator 3 continuously 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 2 hours.

To switch off the shock-warning function, press shock-warning button 2 once, or, when the shock warning is actuated (shock-warning indicator 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 influence. Especially temperature differences occurring 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 possible, 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.

For the accuracy check, an unobstructed measuring distance of 20 m on firm ground between two walls A and B is required. With the measuring tool in the horizontal position, a transit measurement is to be carried out across both axes X and Y (both positive and negative) (altogether 4 complete measurements).

- Mount the measuring tool in the horizontal position onto a tripod 26 (accessory) or place it on a firm and level surface near wall A. Switch the measuring tool on.

Pure geometric diagram with crosshair and circular shapes, no text or symbols present

English | 31

- 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^irc , 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^irc 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 = ±4 mm.

Consequently, the difference d between points I and III for each of the four individual measurements may not exceed 4 mm max.

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 Advice

▶ 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 appear brighter for the eyes.

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.
▶ 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 Laser Receiver (Accessory)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam 28.

When working with the laser receiver, select rotational operation with the highest rotational speed.

Before working with the laser receiver, read and observe the laser receiver operating instructions.

Working with the Remote Control (Accessory)

While pressing the operator buttons, 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 25.

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" tripod 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 26 with a measuring scale on the elevator column, the height difference can be adjusted directly.

Working with Wall Mount/Alignment Unit (Accessory) (see figure A)

You can also mount the measuring tool to the wall mount with alignment unit 30. For this, screw the 5/8" screw 33 of the wall mount into the tripod mount 18 of the measuring tool.

Mounting to a wall: Mounting to a wall is recommended, e.g., for work above the elevation height of tripods or for work on unstable surfaces and without tripod. For this, fasten the wall mount 30, with the measuring tool mounted, as vertical as possible to a wall.

For mounting to the wall, you can either fasten the wall mount 30 with fastening screw 31 to a lath (width maximal 8 mm) or hang it up with two hooks.

Mounting on a tripod: The wall mount 30 can also be screwed onto a tripod with the tripod mount on the back side. This method of fastening is especially recommended for work where the rotational plane is to be aligned with a reference line.

With the alignment unit, the mounted measuring tool can be moved vertically (when mounted to the wall) or horizontally (when mounted to a tripod) within a range of approx. 16 cm. For this, loosen screw 32 on the alignment unit, move the measuring tool to the desired position, and retighten screw 32 again.

Working with the Ceiling Measurement Plate (see figure A)

As an example, the ceiling measurement plate 35 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 transparent half.

Working with the Measuring Plate (Accessory)

With the measuring plate 34, 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 eliminates the necessity of precisely adjusting the measuring tool to the height to be projected.

The measuring plate 34 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 H)

For checking irregularities or projecting gradients, it is recommended to use the measuring rod 27 together with the laser receiver.

A relative millimeter scale ( ±50 cm) is marked on the top of the measuring rod 27. Its zero height can be preset at the bottom of the elevator column. This allows for direct reading of deviations from the specified height.

Work Examples

Projecting/Checking Heights (see figure B)

Position the measuring tool in the horizontal position onto a firm support or mount it onto a tripod 26 (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 measurement plate 34. Project or check the measured height difference at the target location.

Parallel Alignment of a Plumb Beam/Projecting Right Angles (see figure C)

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 directly on the measuring tool with help of the measurement plate 34. Measure the clearance between 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 D)

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.

Working without Laser Receiver (see figure E)

Under favourable light conditions (dark environment) and for short distances, it is possible to work without the laser receiver. For better visibility of the laser beam, either select line operation, or select point operation and manually rotate the rotation head 10 to the target location.

Working with the Laser Receiver (see figure F)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam. When working with the laser receiver, select rotational operation with the highest rotational speed.

34 | English

Measuring Over Long Distances (see figure G)

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 H)

The laser receiver should always be used when working outdoors.

When working on unstable ground, mount the measuring tool onto the tripod 26. Activate the shock-warning function in order to avoid faulty measurements in case of ground vibrations or shock to the measuring tool.

Reflekrujuća polovina plafonske merne ploče poboljšava vidljivost laserskog zraka pri nepovoljnim uslovima, kroz transparentnu polovinu je laserski zrak prepoznatljiv i sa poledjine.

Radovi sa mernom pločom (pribor)

Pomoću merne ploče 34 možete prenositi laserski marker na pod odnosno visinu lasera na zid.

Sa nultim poljem i skalom možete meriti odstu- panje prema željenoj visini i ponovo nanositi na drugom mestu. Tako odpada tačno podešavanje mernog alata na visinu na koju se prenosi.

Merna ploča 34 ima refleksioni sloj koji poboljšava vidljivost laserskog zraka na većem rastojanju odnosno pri jačem sunčevom zračenju. Pojačavanje svetlosti se može samo onda prepoznati, ako gledate na mernu ploču paralelno laserskom zraku.

Radovi sa mernom letvom (pribor) (pogledajte sliku H)

Za kontrolu ravni ili nanošenje nagiba preporučuje se upotreba merne ploče 27 zajedno sa laserskim prijemnikom.

Na mernoj letvi 27 je nameštena gore relativna merna skala (±50 cm). Njenu nultu visinu možete da birate dole na teleskopskom delu.

Radni primeri

Kontrola i prenošenje visina (pogledajte sliku B)

Postavite merni alat u horizontalnom položaju na čvrstu podlogu ili montirajte ga na neki stativ 26 (pribor).

Radovi sa stativom: Usmerite laserskih zrak na željenu visinu. Prenesite odnosno prekontrolišite visinu na odredjenom mestu.

Radovi bez stativa: Pronadjite visinsku razliku izmedju laserskog zraka i visine referentne tačke pomoću merne ploče 34. Prenesite odnosno prekontrolišie izmerenu visinsku razliku na odredjenom mestu.

Paralelno centriranje vertikalnog zraka/nanošenje pravih uglova (pogledajte sliku C)

Ako treba naneti prave uglove ili centrirati medjuzidove, morate centrirati vertikalan zrak 9 da bude paralelan odnosno na istom rasrtojanju do referentne linije (na primer zida).
