Working with the laser target plate
The laser target plate
9
increases the visibility
of the laser beam under unfavourable
conditions and at large distances.
The reflective part of the laser target plate
9
improves the visibility of the laser line. Due to
transparency, the laser line is also visible from
the back side of the laser target plate.
Working with the Tripod
A tripod offers a stable, height-adjustable
measuring support. Position the tool with either
the 1/4-20 tripod mount
4
onto the thread of
a commercially available camera tripod or the
preferred method is to mount to a construction
tripod, use the 5/8-11 tripod mount
3
. Tighten
the tool with the tripod mounting stud.
Laser Viewing Glasses (Optional
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 visualization 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 color perception.

WARNING
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 tool should
always be mounted on a tripod when working
at distances exceeding 65 ft (20 m). If possible,
also set up the tool in the center 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 tool each time before
starting your work.
Should the tool exceed the maximum deviation
during one of the tests, please have it repaired
by a Bosch after-sales service center.
Checking the Horizontal Leveling Accuracy.
A free measuring distance of 16 ft (5 m)on a
firm surface in front of two walls A and B is
required for the check.
– Mount the tool onto a tripod, or place it on
a firm and level surface close to the wall A.
Switch the tool on.
– Direct the laser against the close wall A and
allow the tool to level in. Mark a point on
both walls where the laser indicates (point
y). Mark the center of the laser beam on the
wall (at point y and point z).
– Turn the tool around by 180°, allow it to level
in. The laser line should indicate the same
point within product specification tolerances.
