Main components
The STABILA LAR-100 rotation laser is an easy to operate rotation laser for horizontal
and vertical levelling and plumb lines. It is self-levelling in a range of ± 5°.The laser
beam can be received at distances of up to 150 m or 500 ft with the use ofa 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 stillhave any unanswered
questions, we should be pleased to provide advice over the telephone at any time
on the following telephone number:

When working with the remote control, this must be oriented to the laser's
operating field.

The rotation speed (buttons 19, 20) and the scan function
(button 16) can be set by remote control. Buttons (17) and
(18) are used to move the scanning line and/or the laser
dot to the right or to the left.
Commissioning
- Automatic mode with height of tool alert function (Y LED)
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 (5c) lights up and the Y LED flashes. The splitter penta-
prism 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 posi-
tion, e.g. to adjust its height, set it on a tripod, etc.
Operating modes:
Main applications:
Levelling
Set the unit on a firm base or a tripod.
TTiipp::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 thatyou markthe centre of the laser
beam) or the beam can be received via the receiver.
Integral height adjustment
To adjust the laser dot easily to the desired height, the laser's casing can be moved
vertically by around 80 mm.
To do this, loosen the clamping screw (12) and move the laser's casing upwards on
the guide (see illustration). Once the laser dot has been aligned to the desired
height, retighten the clamping screw (12).

Automatic mode with subsequent readjustment (Y LED)
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 (4b).The red LED 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.
Manual mode without levelling (X- LED)
To be able to markinclinations over 5° in one plane or inclinations in two planes,
once the unit is switched on (button 3), automatic mode can be switched on by
pressing button (4a).The unit can now be tilted in any direction (e.g. by moving
the tripod). This mode is indicated by the red LED (9b).
Manually tilting one axis by ± 5
- with transverse axis levelling ( Z-LED )
This mode enables you, for instance, to lay out gradients in a particular direction.
Manually align the unit precisely at right angles to the direction of the desired
inclined plane using the targeting marks (9). Ideally: align it along a reference line,
e.g. parallel to a wall.
During this time, minor discrepancies from the horizontal are ironed out. Then
the laser unit switches to monitored Automatic mode and the Y LED goes out.

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
Y LED 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 chek-
ked and/or reset to the desired position.

After switching on (via button 3), press button (4c) until the Z LED lights.
The unit is now in height of tool alert function mode.
Buttons (17) and (18) on the remote control can now be used to incline this laser
plane at right angles to the line from the targeting marks. The inclined plane is
automatically levelled horizontally in this line's direction.

CMarking out vertical areas(vertical levelling)
Set the rotation laser on its side feet for vertical levelling (10). Align the unit
manually so that the direction of the vertical laser plane described by the lens is
approximately parallel or at right angles to a reference line (e.g. a wall or a corner).
Press button (3) briefly to switch the unit on. It is now in Height of Tool Alert
function mode.
You can use the remote control to set the rotation speed (17, 18) or to switch
over between point and line function (16). The vertical laser plane described
by the rotating deflected laser beam can only be adjusted in Point mode,
by ± 5°, using buttons (17) and (18). In this way, the laser plane can be
aligned precisely parallel or at right angles to the reference line.

Use as a Plumb-line Laser
The laser can be aligned precisely on a marked cross using the 4 markings (15)
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!

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.
Repeat steps 4 and 5 to obtain Points 3 and 4.
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 SP2’s
beam emission hole in the direction of the wall (using buttons 17, 18 or by hand).
Set up the rotation laser on a smooth, level surface or on a tripod 25 ft or 50 ft /
5m or 10m from a wall with the front facing the wall.
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. Then turn SP2 in the
direction of the wall in the area of measurement point 1.
Please keep as closely as possible to the alignment shown in (H) because this
simplifies any re-adjustment that may be required
The LAR-100 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.

The laser is correctly adjusted when the laser dot is precisely centred between
Points 2 and 4. Adjust the dot's height using buttons (17) and (18) on the remote
control until it is precisely between Points 2 and 4.
Now turn the laser 90° until the y-axis is facing the wall. Now turn SP2 prism until
the laser dot is facing the markings.
If the centre of the laser dot does not correspond to the centre of the dot when the
x-axis was adjusted, switch to Adjustment mode using button (20) on the remote
control.
The Y LED now flashes rapidly. Adjust the height of the laser dot using buttons (17)
and (18) until it is precisely at the height of the centre mark for thex-axis.
The laser is now adjusted again. Pressing button (14) on the remote control saves
the settings. If you do not wish to save the setting, exit Adjustment mode without
saving by pressing the button (3) on the laser. The old setting is then kept unchan-
ged.

If the readings are determined as being outside the tolerance limits during the
horizontal check, the laser can be adjusted as follows. The decisive factor is the
distance between the opposing measurement points, i.e. points 1 + 3 and 2 + 4.
Points 1 and 3 on the unit's y-axis and points 2 and 4 on the unit's x-axis now cor-
respond.For example, if the distance between points 2 + 4 is outside the tolerance
limit of 0.3 mm/m, the laser must be adjusted along this axis!
