Assembly

Inserting/Replacing the Batteries

Use only alkali-manganese batteries.

To open the battery lid 8, press the latch of the battery lid 11 in the direction of the arrow and remove the battery lid. Insert the supplied batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment.

When the battery indication 5 flashes red, the batteries must be replaced.

Always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity.

Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and self-discharge.

Operation

Initial Operation

▶ 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 a long time. 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 or falling of the measuring tool. After heavy exterior impact on the measuring tool, an accuracy check should always be carried out before continuing to work (see "Levelling Accuracy").
▶ Switch the measuring tool off during transport. When switching off, the levelling unit, which can be damaged in case of intense movement, is locked.

Switching On and Off

To switch on the measuring tool, slide the On/Off switch 7 to the “○ o n ” position (when working without automatic levelling) or to the “○ on” position (when working with automatic levelling). Immediately after switching on, the measuring tool sends laser beams out of the exit openings 1.

▶ Do not point the laser beam at persons or animals and do not look into the laser beam yourself, not even from a large distance.

To switch off the measuring tool, slide the On/Off switch 7 to the "off" position. When switching off, the levelling unit is locked.

Deactivating the Automatic Shut-off

The measuring tool switches off automatically after an operating duration of 30 minutes. To deactivate the automatic switch-off, keep the operating mode button 4 pressed for 3 s while switching on the measuring tool. When the automatic switch-off is deactivated, the laser lines briefly flash after 3 s.

▶ 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 activate the automatic shut-off, switch the measuring tool off and then on again (without the operating mode button 4 pushed).

14 | English

Operation Modes (see figures A–D)

The measuring tool has three operating modes between which you can switch at any time:

• Horizontal operation “-”: Produces a horizontal laser line,
• Vertical operation "I": Produces a vertical laser line,
• Cross-line operation “+”: Produces a horizontal and vertical laser line.

After switching on, the measuring tool is in cross-line operating mode. To change the operating mode, press the operating mode button 4.

All three operating modes can be selected either with or without automatic levelling.

Pulse Function

When working with the laser receiver 21, the pulse function must be activated, – independent of the selected operating mode.

In pulse function, the laser lines flash at very high frequency and thus become detectable by the laser receiver 21.

To switch on the pulse function, press button 3. When the pulse function is switched on, the pulse-function indicator 2 lights up green.

When the pulse function is switched on, the visibility of the laser lines is reduced for the human eye. Therefore, shut off the pulse function by pushing button 3 again when working without laser receiver. When the pulse function is switched off, the pulse-function indicator 2 is deactivated.

Automatic Levelling

Working with Automatic Levelling (see figure C)

Position the measuring tool on a level and firm support or attach it to a commercially available photographic tripod.

When working with automatic levelling, push the On/Off switch 7 to the "on" position.

After switching on, the levelling function automatically compensates irregularities within the self-levelling range of ±4^ . The measuring tool is levelled in as soon as the laser lines no longer flash.

If the automatic levelling function is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 4^ from the horizontal plane, the laser beams flash. In this case, bring the measuring tool to the level position and wait for the self-levelling to take place.

In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon relevelling.

Working without Automatic Levelling (see figure D)

For work without automatic levelling, push the On/Off switch 7 to the "on" position. When the automatic levelling is switched off, the laser lines flash continuously.

When the automatic levelling is switched off, the measuring tool can be held by hand or placed on an inclined surface. In cross-line operation, the two laser lines do not necessarily run at a right angle to each other.

Levelling Accuracy

Influences on Accuracy

The ambient temperature has the greatest influence. Especially temperature differences occurring from the ground upward can divert the laser beam.

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.

In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the levelling accuracy each time before beginning work.

First, check both the height as well as the levelling accuracy of the horizontal laser line, then the levelling accuracy of the vertical laser line.

Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service.

Checking the Height Accuracy of the Horizontal Line

For this check, a free measuring distance of 5 m on a firm surface between two walls A and B is required.

- Mount the measuring tool onto a tripod or place it on a firm and level surface close to wall A. Switch on the measuring tool. Select cross-line operation with automatic levelling.

- Direct the laser against the close wall A and allow the measuring tool to level in. Mark the centre of the point where the laser lines cross each other on the wall (point 1).

- Turn the measuring tool by 180^ , allow it to level in and mark the cross point of the laser lines on the opposite wall B (point II).

English | 15

- 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 a tripod or by underlaying, if required) in such a manner that the cross point of the laser lines is projected against the previously marked point IT on the wall B.

- Without changing the height, turn around the measuring tool by 180^ . Direct it against the wall A in such a manner that the vertical laser line runs through the already marked point I. Allow the measuring tool to level in and mark the cross point of the laser lines on the wall A (point III).

- The difference d of both marked points I and III on wall A indicates the actual height deviation of the measuring tool.

The maximum permitted deviation d_max is calculated as follows:

d_max = double distance of the walls x 0.3 mm/m Example: With a 5 metre distance between the walls, the maximum deviation must not exceed

d_max=2×5m×0.3mm/m=3mm . Thus, the marks must be more than 3 mm apart.

Checking the Levelling Accuracy of the Horizontal Line For the check, a free surface of approx. 5 x 5 metres is required.

- Set up the measuring tool on a firm, level surface between both walls A and B. Allow the measuring tool to level in while in horizontal operation.

- At a distance of 2.5 metres from the measuring tool, mark the centre of the laser line (point 1 on wall A and point 11 on wall B) on both walls.

- Set up the measuring tool 5 metres away turned by 180^ is t not and allow it to level in.

• Align the height of the measuring tool (using a tripod or by underlaying, if required) in such a manner that the centre of the laser line is projected exactly against the previously marked point IT on wall B.
• Mark the centre of the laser line as point III (vertically above or below point I) on the wall A.
• The difference d of both marked points I and III on wall A indicates the actual deviation of the measuring tool from the level plane.

The maximum permitted deviation d_max is calculated as follows:

d_max = double distance of the walls x 0.3 mm/m Example: With a 5 metre distance between the walls, the maximum deviation must not exceed

d_max = 2 × 5 m × 0.3 mm/m = 3 mm . Thus, the marks must not be more than 3 mm apart.

16 | English

Checking the Levelling Accuracy of the Vertical Line

For this check, a door opening is required with at least 2.5 m of space (on a firm surface) to each side of the door.

- Position the measuring tool on a firm, level surface (not on a tripod) 2.5 m away from the door opening. Allow the measuring tool to level in while in cross-line operation mode, and direct the laser beams at the door opening.

- Mark the centre of the vertical laser line at the floor of the door opening (point 1), at a distance of 5m beyond the other side of the door opening (point 11) and at the upper edge of the door opening (point 111).

• Position the measuring tool on the other side of the door opening directly behind point 11. Allow the measuring tool to level in and align the vertical laser line in such a manner that its centre runs exactly through points 1 and 11.
• The difference d between point 111 and the centre of the laser line at the upper edge of the door opening results in the actual deviation of the measuring tool from the vertical plane.
• Measure the height of the door opening.

The maximum permitted deviation d_max is calculated as follows:

d_max = double height of the door opening x 0.3 mm/m Example: With a door opening height of 2 metres, the maximum permitted deviation is

d_max = 2 × 2 m × 0.3 mm/m = 1.2 mm . Thus, the marks must not be more than 1.2 mm apart.

Working Advice

▶ Always use the centre of the laser line for marking. The width of the laser line changes with the distance.

Working with the Alignment Plate

With the alignment plate 12, the measuring tool can be aligned by a reference line or the vertical laser line can be indicated at an angle of 45^ or 90^ to a reference line.

Position the measuring tool via the tripod mount 6 onto the pin 16 of the alignment plate. Position it in such a manner on the alignment plate that the vertical laser line (depending on the requested angle) runs centrally through the alignment aid 13, 14 or 15.

Align the alignment plate 12 with the corresponding alignment aids 13, 14 or 15 to the desired reference line.

Working with the Measuring Plate (Accessory) (see figures E-F)

With the measuring plate 20, 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 20 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 Tripod (Accessory)

A tripod offers a stable, height-adjustable measuring support. Place the measuring tool via the tripod mount 6 onto the 1/4" male thread of the tripod and screw the locking screw of the tripod tight.

Working with the Laser Receiver (Accessory) (see figure G)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser lines 21. When working with the laser receiver, switch the pulse function on (see "Pulse Function", page 14).

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.

Work Examples (see figures H-K)

Laying Flooring Plates at a 45° Angle (see figure J)

Position the measuring tool via the tripod mount 6 onto the pin 16 of the alignment plate. Position it in such a manner on the centred protrusion of the alignment plate 12 that the ver-

English | 17

tical laser line runs centrally through the alignment aid 15.

Then, align the alignment plate with the alignment aids 13 or 14 with regard to the reference line.

For cross line or in vertical operation, the vertical laser line on the floor indicates a 45^ angle to the reference line. Align the flooring plates with regard to this line.

Projecting Plumb Points to the Ceiling (see figure K)

Draw two lines crossed at a right angle through the point that you want to project to the ceiling. Place the alignment plate 12 onto the crossed lines and align it with the alignment aids 13 and 14 on the cross.

Position the measuring tool via the tripod mount 6 onto the pin 16 of the alignment plate. Position it in such a manner on one of the two outer protrusions on the alignment plate that the vertical laser line runs centrally through the corresponding alignment aid 13 or 14. Select vertical operation and draw the centre of the line running across the measuring tool to the ceiling.

Turn the measuring tool on the alignment plate by 90°. Pay attention not to move the position of the alignment plate. After levelling in, draw the cross point of the vertical laser line to the already drawn line. The cross point of both lines is the projected plumb point.
