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:
Operating instructions
The STABILA LAPR-150 rotation laser is an easy to operate rotation laser for horizon-
tal and vertical levelling and plumb lines. It is self-levelling in a range of ± 1°. The
laser beam can be received at distances of up to 90 m (570 ft) with the use of a
receiver, even when it is no longer visible to the naked eye.

Leveling
Set the unit on a firm base or tripod so that the bubble in the enclosed vial (9)
does not touch the sides of the vial. This vial is used only for rough adjustment.
Tip: It is useful to set up the rotation laser safely at the same distance to the
subsequent measurement points.
Main applications:
Please note that the center
of laser dot is marked!
Getting started
Move the slider switch (3a) upwards to switch the laser ON.
If the unit is outside its self-leveling range, the laser starts to flash.
Aligning:

3. Re-fasten the clamp.
Tilt the upper part of the casing until the bubble
in the vial no longer touches the edge of the vial.
Release the clamp.

Marking out vertical areas (vertical leveling)
Tilt the motor head 90° in its end position and engage the deflection optics in the
end position. Align the unit so that the vertical plane described by the optics is
parallel or at right angles to a line of reference. Switch the laser on via the sliding
switch 3). Align the casing by turning the unit on the base plate. Because of the
vibration that this may cause, the monitoring function may cause the laser beam to
flash.
Generating parallel planes:
Creating vertical reference areas, e.g.
measuring dividing walls.
Measuring tiles, panels, parquet (floors,
ceilings, walls), measuring right angles
simply by swiveling the unit.
At right angles to the wall:

Roughly align the laser using the built-in vial, i.e. set the bubble roughly in the
centre of the vial. Turn the deflector prism's beam emission opening by hand in
the direction of the wall.
The LAPR-150 rotation laser has been designed for building site use and leaves our
factory perfectly calibrated. As with any precision instrument, however, its
calibration 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-leveling
range.

If the difference between the control points is less than 2mm ( 1/8”) at 5m ( 26ft )
distance and 4mm ( 3/16” ) at 10m ( 39ft ) distance the permissible tolerance of
± 0.2 mm/m ( ± 1/4” over 100ft ) is being maintained.
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 center of the dot!
Set up the rotation laser on a smooth, level surface or on a tripod 5m ( 26 ft )
or 10m ( 39ft ) from a wall with the front side facing the wall.
Turn the complete unit 90° without altering the height of the laser (i.e. the tripod
must not be altered) and turn the deflection prism in the direction of the wall
again in the area of measurement point 1.

Roughly align the laser using the built-in vial, i.e. set the bubble roughly in the
center of the vial. Set the tripod height approximately as it was for position 1.
Now place laser unit on its tripod directly in front of wall B.
Mark the position of the visible laser dot on wall B (Point 2).
Switch the unit on.
Switch the unit off. Turn the complete unit 180° without altering
the height of the laser. The tripod must not be altered.
Mark the position of the visible laser dot on wall A (Point 1).
Switch the unit on.
Direct the laser beam on wall A.

Mark the center of the laser dot on wall A for Point 4.
Measure the corresponding heights of the points , either in relation
to the floor or to the point below, which is classed as being at 0 mm.
It is essential that the plus or minus
signs are calculated correctly.

Vertical check (motor head tilted 90°)
Roughly align the laser using the built-in vial, i.e. set the bubble roughly in
the center of the vial.
Tilt the motor head 90° in the direction of wall A.
The deflection optics should be set in the end position.
Set up the rotation laser on a tripod directly in front of wall A.
Two parallel wall surfaces at least 5m ( 17 ft ) apart are required for the vertical check.

Do not submerge the laser.
Do not store the laser when wet.
Dry the laser and case before
putting the laser away.
Do not unscrew !
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 reac-
tion to turn one's head. This equipment
can therefore be used without additio-
nal protective measures. Nevertheless,
you should not look directly into the
laser beam. The laser goggles enclosed with these units
are not safety goggles. They are designed
to make the laser light easier to see.
Do not let the unit
fall into children's
hands!
EN 60825-1 : 08 05
The use of operating and adjustment equipment other than that indicated here
or the use of other procedures can lead to dangerous exposure to radiation.
