Work Examples - CST/BERGER LM800 Serie Manual Original

Mounting to a wall: Mounting to a wall is recom-
mended, 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 29, with the
measuring tool mounted, as vertical as possible to a
wall.
Mounting on a tripod: The wall holder 29 can also be
screwed onto a tripod with the tripod mount on the
back side. This method of fastening is especially rec-
ommended for work where the rotational 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.
Working with the Laser Target Plate
(Accessory)
With the laser target plate 28, 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 pre-
cisely adjusting the measuring tool to the height to be
projected.
The laser target plate 28 has a reflecting coating
which improves the visibility of the laser beam from a
larger distance or in case of strong sun rays. The lumi-
nosity 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 differ-
ence between the laser beam and the height at the
reference point with the laser target plate 28. Project
or check the measured height difference at the target
location.

Indicating a Plumb Line/Vertical Plane
(LM800DP)
To indicate a plumb line or a vertical plane, set up the
measuring tool in the vertical position. When the ver-
tical plane is supposed to run at a right angle to a ref-
erence line (e.g. a wall), then align the plumb beam 19
with this reference line.
The plumb line is indicated by the variable laser beam 12.
Troubleshooting
Corrective Measures
Cause
Measuring tool does not switch on or reacts
incorrectly
Battery pack empty or
defective
Battery pack incorrectly
inserted (wrong polarity)
Battery-pack contacts
damaged from run out
battery pack
Contacts of battery pack
and housing lack contact
Measuring tool does not rotate and level in
Measuring tool not within
the self-levelling range
Signal for exceeding the self-levelling range is
being indicated despite horizontal set-up
Malfunction of the level-
ling procedure
Measuring tool rotates but does not level in
Measuring tool without
automatic levelling while
in operation
Rotor does not rotate or rotates too slowly;
shock-warning indicator 9 and indicator for
working without automatic levelling 7 flashing
Spindle-motor error
Measuring tool reacts implausible after press-
ing a button
When the corrective measures do not eliminate an
error, please contact an authorised service agent for
Bosch power tools.
