Influences on Accuracy
The ambient temperature has the greatest
influence, especially temperature differences
occurring from the ground upward can divert
the laser beam.
As thermal fluctuation is closest to the ground,
if possible the tool should be mounted on a
commercially available tripod and placed in
the center of the work area.
Apart from exterior 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.
First, check both the height as well as the
leveling accuracy of the horizontal and vertical
laser line.
Should the 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 approximately 26 feet on a firm surface
between two walls A and B is required.
– Mount the tool onto a tripod or place it on a
firm and level surface close to wall A.

Switch on the tool.
– Direct the laser against the close wall A and
allow the tool to level in. Mark the center of

Leveling Accuracy

the point where the laser lines cross each
other on the wall (point I).
– Turn the tool by 180°, allow it to level in and
mark the cross point of the laser lines on
the opposite wall B (point II).
– Without turning the tool, position it close to
A
wall B. Switch the tool on and allow it to
level in.
– Align the height of the 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 II on the wall B.
– Without changing the height, turn around
the 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 tool to level in and mark the 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 tool.
The maximum permitted deviation dmax is

calculated as follows:
d
= double distance of the walls x 0.0036
max
mm/m Example: With a 26 ft distance
between the walls, the maximum deviation
must not exceed dmax = 2 x 26 ft x 0.0036 in/
ft = 3/16 In. (0.188in) Thus, the marks must
not be more than 3/16 of an inch apart.
