– After the levelling, mark the centre of the laser beam on wall
A (point I).

180°
– 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.
A
– Align the height of the measuring tool (using the tripod or by
propping), so that the centre of the laser beam runs exactly
against the previously marked point II on wall B.
A
d
– 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 procedure
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.

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 im-
proved finding of the laser beam 23.
RL25HV: When working with the laser receiver, select rotation-
al 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 26.
The receiption lenses 1 for the remote control are located on
four sides next to the rotation head.
Before working with the remote control, read and observe the
remote control operating instructions.
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 20 onto the 5/8" male thread of the tripod and
screw the locking screw of the tripod tight.
On a tripod 25 with a measuring scale on the elevator column,
the height difference can be adjusted directly.
Working with Wall Mount/Alignment Unit (Accessory)
(RL25HV)
You can also mount the measuring tool to the wall mount with
alignment unit 28. For this, screw the 5/8" screw of the wall
mount into the tripod mount 20 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 unsta-
ble surfaces and without tripod. For this, fasten the wall mount
28, with the measuring tool mounted, as vertical as possible to
a wall.
Mounting on a tripod: The wall mount 28 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 rota-
tional 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. 15 cm.
