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 indica-
tor 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 Rota-
tional 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.
Accuracy Check of the Measuring Tool
Influences on Accuracy
After the precise spirit level centring, the ambient tem-
perature 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 dis-
tances exceeding 20 m. If possible, also set up the
measuring tool in the centre of the work area.
Apart from exterior influences, device-specific influ-
ences (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 cen-
tre of the rotating laser beam.
Should the measuring tool exceed the maximum devi-
ation during one of the tests, please have it repaired
by a Bosch after-sales service.
Checking the Levelling Accuracy in the Horizon-
tal 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 meas-
uring tool accurately with the spirit levels and then
switch it on again.
– Mark the centre of the laser beam on the wall
(point
I
).
– Rotate the measuring tool by 180°, re-align it
accurately with the spirit levels and mark the cen-
tre 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.
