OBJ_BUCH-1045-001.book Page 7 Wednesday, July 22, 2009 10:40 AM

Mount the battery lid 22 again and tighten it with screw 21.

f Remove the batteries/rechargeable batter-

ies from the measuring tool when not using

it for longer periods. When storing for longer periods, the batteries/rechargeable batteries can corrode and discharge themselves.

Operation

Initial Operation

f Protect the measuring tool against moisture

and direct sun light.

f Do not subject the measuring tool to

extreme 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 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 falling down of the

measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out an accuracy check (see “Accuracy Check of the

Measuring Tool”, page 8) each time before continuing to work.

Setting Up/Aligning the Measuring Tool

Horizontal position

Note: Precise levelling work is only possible with exactly centred spirit levels. While working, periodically check if the air bubbles are still centred in the respective spirit levels.

If the air bubble in a spirit level should not move when turning the levelling screws, lightly tap your finger against the measuring tool above the spirit level to free the air bubble.

Switching On and Off

f 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.

f 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 switch on the measuring tool, press button 15.

Immediately after switching on, the measuring tool sends out the variable laser beam 10 and the plumb beam 1. The measuring tool starts in rotational operation with high rotational speed.

To switch off the measuring tool, press button 15 until all indicators and the laser beams go out.

Operating Modes

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.

Vertical position

Position the measuring tool on a firm surface in the horizontal or vertical position, mount it to a tripod or to the wall mount 26 with alignment unit.

The course of the X- and Y-axis on the measuring tool are marked on the housing next to the rotation head 3.

Horizontal position: Align the measuring tool in the

X-axis by turning levelling screw 6 so that the air bubble of spirit level 9 for the X-axis is exactly centred.

Then align the measuring tool in the Y-axis by turning levelling screw 7 so that the air bubble of spirit level 4 for the Y-axis is exactly centred.

Vertical position: Align the measuring tool by turning levelling screw 7 so that the air bubble of spirit level 8 for the vertical position is exactly centred.

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.

OBJ_BUCH-1045-001.book Page 8 Wednesday, July 22, 2009 10:40 AM

Rotational Operation (600/150 min

-1

)

For rotational operation with high rotational speed, press button 15 until indicator 18 lights up.

For rotational operation with low rotational speed, press button 15 until indicator 17 lights up.

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 23.

Point Operation

For point operation, press button 15 until indicator 16 lights up.

Line Operation (45°/22°)

For rotational operation with large aperture angle, press button 15 until indicator 12 lights up.

For rotational operation with small aperture angle, press button 15 until indicator 13 lights up.

Note: Due to inertia, it is possible for the laser to slightly move beyond the end point of the laser line.

Rotating the Laser Point/Laser Line in the Rotational Plane

To direct the laser point or the laser line onto a desired location, rotate the rotation head 3 manually or with the remote control 27 to the desired position.

For manual rotating in line operation, briefly hold the rotation head 3 tight until the rotation is stopped, and then turn it to the desired position.

Checking the Levelling Accuracy in the Horizontal Position

A free measuring distance of 30 m on a firm surface in front of a wall is required for the check. A complete measuring procedure each must be carried out for the

X- and Y-axis.

– Mount the measuring tool in the horizontal position onto a tripod or place it on a firm and level surface at a distance of 30 m to the wall. Align the measuring tool accurately with the spirit levels and then switch it on again.

30 m

– Mark the centre of the laser beam on the wall

(point I).

180˚

Accuracy Check of the Measuring Tool

Influences on Accuracy

After the precise spirit level centring, the ambient temperature has the largest influence on the accuracy.

Especially temperature differences occurring from the ground upward can deflect 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.

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.

To check the accuracy, select rotational operation and, if required, use the laser receiver to mark the centre of the rotating laser beam.

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

8 | English

– Rotate the measuring tool by 180°, re-align it accurately with the spirit levels and mark the centre point of the laser beam on the wall (point II).

Take care that point II is as vertical as possible above or below point I.

– The difference d of both marked points I and II on the wall results in the actual height deviation of the measuring tool for the measured axis.

Repeat the measuring procedure for the other axis.

For this, turn the measuring tool by 90° before starting the measuring procedure.

On the measuring distance of 2 x 30 m = 60 m, the maximum allowable deviation is:

60 m x ±0.2 mm/m = ±12 mm.

Consequently, the difference d between points I and

II for each of the two measurements may not exceed

12 mm.

2 610 A12 214 • 22.7.09

OBJ_BUCH-1045-001.book Page 9 Wednesday, July 22, 2009 10:40 AM

Checking the Levelling Accuracy in the Vertical

Position

A free measuring distance of 10 m on a firm surface in front of a wall is required for the check. Fasten a plumb bob rope to the wall.

– Mount the measuring tool in the vertical position onto a tripod, or place it on a firm and level surface.

Align the measuring tool accurately with the spirit level and switch it on.

– Align the measuring tool such that the laser beam impinges centrally on the plumb bob rope at the upper end. The difference d between laser beam and plumb bob rope at the bottom end of the rope results in the deviation of the measuring tool to the vertical line.

For a 10 m high measuring distance, the maximum allowable deviation is:

10 m x ±0.2 mm/m = ±2 mm.

Thus, the difference d must not exceed 2 mm.

Working Advice

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 appear brighter for the eyes.

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 glasses do not afford complete UV protection and reduce colour perception.

Working with the Laser Receiver (Accessory)

(see figure C)

Under unfavourable light conditions (bright environment, direct sunlight) and for larger distances, use the laser receiver for improved finding of the laser beam 25.

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)

When pressing the operating controls, it is possible to bring the measuring tool out of its level position. This effect is prevented by using the remote control 27.

The receiption lense 11 for the remote control is located on the front side of the measuring tool.

For information on working with the remote control 27, see “Remote control”, page 12.

Working with the Tripod (Accessory)

The measuring tool is equipped with a 5/8" tripod mount 5 each for horizontal and vertical operation.

Place the measuring tool via the tripod mount 5 onto the 5/8" male thread of the tripod and screw the locking screw of the tripod tight.

Adjust the tripod roughly before switching on the measuring tool.

Working with Wall Holder/Alignment Unit

(Accessory) (see figure B)

You can also mount the measuring tool to the wall mount with alignment unit 26. For this, screw the 5/8" screw of the wall mount into one of the tripod mounts

5 of the measuring tool.

Fasten the wall holder 26 with the clamping screws to stable, as level or vertical as possible objects, with a max. thickness of 6 mm.

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 holder 26, with the measuring tool mounted, as vertical as possible to a wall.

Horizontal assembly: The wall holder can ease the alignment of the vertical laser plane to a reference line.

For this, fasten the wall holder horizontally and mount the measuring tool in vertical position.

With the alignment unit, the mounted measuring tool can be moved vertically (when mounted to the wall) or horizontally within a range of approx. 17 cm.

Working with the laser target plate (Accessory)

With the laser target plate 24, the laser mark can be projected on the ground/floor or against a wall. With the magnetic holder, the laser target plate can also be fastened to ceiling constructions.

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 laser target plate 24 has a reflecting coating which improves 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.

Work Examples

Sighting Out a Reference Height

At the beginning of your work, mark a reference height at a suitable distance (furthest possible) on a stable surface (e.g. on a tree or building), which you can use as your reference point.

While working, periodically check the working height to ensure that it has not changed with respect to the reference height.

Projecting/Checking Heights

Place the measuring tool in horizontal position on a firm surface or mount it to a tripod (accessory).

Working with expandable 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 the laser target plate 24. Project or check the measured height difference at the target location.

Indicating a Plumb Line/Vertical Plane

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 1 with this reference line.

The plumb line is indicated by the variable laser beam 10.

Operation Maintenance and Service

Initial Operation

f Protect the remote control against moisture

and direct sunlight.

f Do not subject the remote control 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 remote control to adjust to the ambient temperature before putting it into operation.

The remote control remains ready for operation as long as batteries with sufficient voltage are inserted.

Set up the rotational laser level in such a manner that the signals of the remote control directly reach the receiption lens on the rotational laser level (for this, see the operating instructions of the rotational laser).

When the remote control cannot be pointed directly against a receiption lens, the working range is reduced. By reflecting the signal (e.g. against walls), the working range can be improved even for indirect signals.

After pressing a button on the remote control, the illuminated operation indicator 29 indicates that a signal was sent out.

Switching the rotational laser on/off with the remote control is not possible.

Maintenance and Cleaning

Keep the remote control clean at all times.

Do not immerse the remote control into water or other fluids.

Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents.

If the remote control should fail despite the care taken in manufacture and testing, repair should be carried out by an authorised customer services agent for

Bosch power tools. Do not open the remote control yourself.
