Main components
The STABILA LAR-200 rotation laser is an easy to operate rotation laser for horizontal
levelling and plumb lines in a sealed housing ( IP65). It is self-levelling in a range of
± 5°. The laser beam can be received at distances of up to 150 m with the use of a
receiver, even when it is no longer visible to the naked eye.
We have endeavoured to explain the unit's handling and functioning in as clear
and comprehensible manner as possible. If, however, you still have any unanswered
questions, we should be pleased to provide advice over the telephone at any time
on the following telephone number:

- Automatic mode with height of tool alert function
For safety reasons, the rotation laser always switches itself off all when it is
switched on in this operating mode!
The unit can be switched on by briefly tapping button (3). Automatic levelling starts
immediately. The green LED (5b) lights up and the LED (4) flashes. The splitter pen-
taprism begins to rotate and the laser beam comes on. After automatic levelling,
you have approximately 30 seconds in which to set the laser unit in the desired
position, e.g. to adjust its height, set it on a tripod, etc.
During this time, minor discrepancies from the horizontal are ironed out. Then the
laser unit switches to monitored Automatic mode and the LED (4) goes out.
Operating modes:
Main applications:
Levelling
Set the unit on a firm base or a tripod.
Tip: It is useful to set up the rotation laser centrally to
the subsequent measurement points.
Pressing the button (3), switches the rotation laser ON
and it starts to level itself automatically. Once levelling
is complete, the laser begins to rotate. Depending on
the brightness of the ambient light, you can either use
the laser beam, if easily visible, for marking directly
(always ensure that you mark the centre of the laser
beam) or the beam can be received via the receiver.
Please note that the centre of laser dot is marked!
NB:
In Class II laser equipment, your eyes
are protected from accidental, short-
term exposure to the laser beam by
the lid-closing reflex and/or the reflex
reaction to turn one's head. This
equipment can therefore be used
without additional protective measu-
res. Nevertheless, you should not look
directly into the laser beam. The laser goggles enclosed with these
units are not safety goggles. They are desi-
gned to make the laser light easier to see.
Do not let the unit fall into children's
hands!

Automatic mode with subsequent readjustment
In many operating conditions (e.g. on strongly vibrating surfaces), it is useful for
the rotation laser to level itself constantly to eliminate any discrepancies that may
arise. After switching it on with button (3), the unit can be switched to this mode by
pressing button (4). The red LED (4) indicates that this mode is active.
Minor discrepancies from the horizontal (from minor tremors) are compensated for.
If these disruptive influences are too great, rotation stops, the laser beam switches
off and the laser unit levels itself again automatically. Once re-levelling is comple-
te, the splitter Pentaprism starts to rotate again.
Height of tool alert function
Minor tremors or vibrations are automatically compensated for only up to a set
threshold. If these disruptive influences are greater than this, the height of tool
alert function engages and rotation stops. The laser beam switches off and the
LED (4) flashes. You must switch the laser unit off using button (3) and then switch it
on again.
Disruptive influences that can lead to adjustment of the precise alignment and the
laser beam's setting do not therefore go unnoticed. When there are disruptive
influences present, the height of tool alert function requires the laser to be checked
and/or reset to the desired position.
Use as a Plumb-line Laser
The laser can be aligned precisely on a marked cross
using the 4 markings (9) on the base to transfer a
plumbline from the floor marking to the ceiling. The
point where the cross intersects corresponds to the
SP1 vertical laser emitter.
A correct result can only be obtained in Automatic
mode with the unit set on a level surface!
The LAR-200 rotation laser has been designed for building site use and leaves our
factory perfectly calibrated. As with any precision instrument, however, its calibra-
tion must be regularly checked. The unit should be checked before starting any
new tasks, particularly when the unit has been exposed to strong vibrations. After
an impact, the unit should be checked throughout its whole self-levelling range.

Mark the position of the visible laser dot on the wall (Point 2).
Mark the position of the visible laser dot on the wall - Measurement 1 (Point 1).
Because the diameter of the beam depends on the distance, you must always
only use the centre of the dot!
Switch the unit on (button 3) and wait for it to level automatically.
Turn the complete unit 90° without altering the height of the laser
(i.e. the tripod must not be altered). Let the unit level automatically again.

If the difference between the 4 control points is less than 1/16" at 25ft
(1mm at 5m) distance and 1/8" at 50ft (2 mm at 10m) distance the permissible
tolerance of ± 1/8" over 100ft (± 0.1 mm/m) is being maintained.
Points 1 and 3 on the unit's y-axis and points 2 and 4 on the unit's x-axis now
correspond.
Set up the rotation laser on a smooth, level surface or on a tripod 25 ft or 50 ft

• Dirty lens glass on the beam emitter detracts from the quality of the beam.
It should be cleaned with a soft cloth.
• Clean the laser unit with a damp cloth. Do not spray or immerse the unit!
Do not use solvents or thinners!
Care and maintenance
The LAR-200 rotation laser must be handled carefully, in the same way as any
