1. Intended use
Congratulations on the purchase of your STABILA measuring tool. The STABILA LAR 160 /
LAR 160 G is an easy-to-use rotation laser for horizontal and vertical levelling, including
obtaining plumb lines. The LAR 160 / LAR 160 G has a sealed enclosure (IP 65) for use on
building sites. It is self-levelling within a range of ± 5°.
The laser beam can be picked up using a receiver even where it can no longer be dis-
cerned with the naked eye.
LAR 160 G:
Receivers must be suitable for green laser beams.
If you still have questions aer reading through the operating instructions, you
can obtain advice by telephone:

2. Safety instructions for laser units
In Class 2 laser units, your eyes are usually protected from accidental, short-term expo-
sure to the laser beam by the eyelid-closing reflex and/or the reflex reaction to turn
one’s head. If a laser beam hits your eye, deliberately close your eyes and move your
head out of the path of the beam. Do not look into the direct or reflected beam.
The STABILA laser goggles available for our laser units are not safety eyewear:
their function is to improve the visibility of the laser beam.
• Do not aim the laser beam directly at people!
• Avoid dazzling other people with the unit!
• Keep the unit out of the reach of children!
• If operating or adjustment equipment that has not been specied here is used, or
if the unit is not operated in the ways described here, this may result in hazardous
exposure to radiation!

4.2 Switching the unit on
Place the laser unit in the appropriate working position
(vertical or horizontal). Press the ON/OFF button to switch
the laser on and o. The green LED indicates that the unit is
switched on.
Activating the self-levelling function causes the unit to level
itself automatically. The laser beam does not (yet) flash
or rotate. Once levelling is complete, the beam stays on
constantly and begins to rotate.
Fine adjustments can still be made within the first
30 seconds. These 30 seconds are indicated by a slow
flashing of the white “TILT” LED.
4.1 Battery insertion/replacement
Open thebattery compartment lid (9) in the direction of the
arrow and insert new batteries in the battery compartment
as indicated by the symbol.
Suitable rechargeable batteries can also be used.
LED indicator:
Orange LED: Battery capacity low
- Insert new battery
Used batteries should be disposed of at
appropriate collection points.
Do not dispose of in household waste.
If you do not intend to use the unit for an
extended period, remove the batteries.
The laser lines flash if the laser unit is at
too steep an angle.
The laser unit is outside the self-levelling
range and cannot level itself automatically.

5.1 Automatic operation with tilt function
The tilt function warns if any interference to the laser has
occurred that may cause misalignment. This ensures that
such interference does not go unnoticed.
This mode is always set directly after the unit is switched on.
In “Automatic” operation, the laser unit levels itself
automatically.
Place the laser unit in the appropriate working position
(vertical or horizontal). Press the button (ON/OFF) once.
The LAR 160 / LAR 160 G is in now in “Automatic operation
with tilt function”.
The automatic levelling process begins. Once levelling is
complete, the beam stays on constantly and begins to
rotate. Fine adjustments can still be made within the first
30 seconds. These 30 seconds are indicated by a slow
flashing of the white “TILT” LED.
After 30 seconds, the white “TILT” LED lights up steadily,
meaning the tilt function is active. If any event occurs that
could result in the laser unit being deflected from its exact
alignment and setting, the beam ceases to rotate. The
“TILT” LED flashes red. If this occurs, check the laser unit
and set it up once again if necessary.
You must press the “TILT” button to confirm the tilt function.
Only after this can you proceed further.
If you are working in conditions where interference is
present (e.g. on vibrating surfaces), it is recommended
that you select “Automatic operation with relevelling”.

5.2 Automatic operation with relevelling
In some working conditions (where shocks or vibrations
aecting the surface occur, for example), the tilt function is
disruptive. With automatic relevelling, on the other hand, the
unit is readjusted each time it is knocked out of alignment.
Place the laser unit in the appropriate working position
(vertical or horizontal). Press the button (ON/OFF) once.
Then press the “TILT” button to deactivate the tilt function.
The green LED indicates that the unit is switched on and
the laser beam flashes. Once levelling is complete, the
beam stays on constantly and begins to rotate.
When incidents occur that cause misalignment, the laser
beam ceases to rotate. The laser beam flashes. Now the
laser unit relevels itself. Once levelling is completed, the
laser beam begins to rotate once more.
If the unit is inclined at an angle ≥ 5°, it is outside the
self-levelling range and cannot level itself automatically.
Any deviations from the original alignment/setting of the
unit are not indicated (-> Tilt function).
Pressing the “TILT” button again reactivates the tilt function.

en
5.3 Manual operation
In manual operation, neither the tilt function nor relevelling
are active. In this mode the unit is aligned entirely by hand.
The unit does not level itself.
Place the laser unit in the appropriate working position
(vertical or horizontal). Press the “ON/OFF” button once.
The green LED indicates that the unit is switched on and
the laser beam flashes. The white “TILT” LED flashes.
Press the “man” button to deactivate the tilt function
and automatic relevelling. The white “man” LED lights up
steadily. The laser beam rotates.
The laser plane can be set up by direction-nding or by
taking measurements. The inclinometer (available as an
accessory) can be used to aid setting up the inclination.
Pressing the “man” button again deactivates manual oper-
ation. The unit reverts to mode 6.1 “Automatic operation
with tilt function”.

6. Functions
Rotation function
The laser beam rotates through 360° around its axis:
• Horizontal
• Vertical
Right angle (90°)
In vertical operation, the point laser and the rotation plane
form a 90° angle. This allows right angles to be created.
Plumb-line function
Transfers a determined point from the floor to the ceiling.
To transfer a plumb line from a floor marking to the ceiling,
the laser unit is aligned exactly with the cross mark with
the 4 marking points (10). The point of intersection of the
cross mark corresponds to the exiting laser plumb line. In
automatic mode a correct result can only be obtained if the
floor surface is level.

8.2 Horizontal check
Checking the horizontal laser line level
Be sure to adhere as closely as possible to the orientation
of the unit as shown.
1. Place the LAR 160 / LAR 160 G on a horizontal surface
or on a tripod at a distance of at least 10 m (50’) from a
wall, with the operator panel towards the wall.
2. Switch the laser unit on and wait until it has auto
matically levelled itself.
3. Mark the centre of the visible laser line on the wall
– measurement 1 (point 1). A receiver can also be used.
4. Rotate the entire laser unit through 90° without altering
the height of the laser (i.e. do not change the tripod
height). Allow the unit to level itself again.
5. Mark the centre of the laser line on the wall (point 2).
6. Repeat steps 4 and 5 twice to obtain points 3 and 4.
7. If the dierences between the four control points are
less than 2mm (1/8”) for a distance of 10m (50 ‘), the
unit is within its permitted tolerance of ± 0.1 mm/m
(± 18” over 100). Here points 1 and 3 correspond to
the unit’s x-axis and points 2 and 4 to its y-axis.

8.1 Checking Accuracy
The STABILA LAR 160/ LAR 160 G rotation laser has been
designed for construction sites and has le our factory
in a correctly adjusted condition. As with all precision
instruments, you should regularly check the calibration
accuracy of the unit. Before starting work each day, and
particularly if the unit has been exposed to heavy shocks
or vibrations, a check of the calibration should be
carried out.

Checking the vertical plumb-line laser
To perform the vertical check, two parallel wall surfaces
are required with a separation S of at least 10 metres.
1. Position the rotation laser directly in front of one of
the walls, A, on its side-mounted feet as for vertical
levelling.
The LAR 160 / LAR 160 G can also be mounted on a
tripod.
2. Switch on the laser unit.
3. Once automatic levelling is complete, mark the
position of the laser point on wall A. Point 1.
4. Rotate the LAR 160 / LAR 160 G through 180° and align
with wall B using the plumb-line laser. Do not adjust
the height.
5. Once automatic levelling is complete, mark the position
of the plumb-line laser point on wall B. Point 2.
6. Now reposition the laser unit so that it is directly in
front of wall B. Align the LAR 160 / LAR 160 G with wall
B using the plumb-line laser.
7. Once automatic levelling is complete, rotate the
plumb-line laser point and move it vertically until it
exactly covers point 2.
8. Rotate the LAR 160 / LAR 160 G through 180° and align
with wall A using the plumb-line laser. Do not adjust
the height.
9. Rotate the plumb-line laser point until it covers the
marking line of point 1 exactly.
10. Once automatic levelling is complete, mark the
position of the plumb-line laser point on wall A. Point
3.
11. Measure the vertical distance between points 1 and 3.
8.3 Vertical check
Where the distance between walls A and B is 10m (50 ‘),
the distance between points 1 and 3 must not be greater
than 2mm (1/8”).
