The STABILA LAR-350 is an easy-to-use rotation laser for
horizontal and vertical levelling, including obtaining plumb
lines. The LAR-350 has a sealed enclosure (IP 65) for use on
construction 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 discerned with the naked eye.
If you still have questions aer reading through the
operating instructions, you can obtain advice by

Read the safety instructions and operating instructions through carefully.
Allow only qualied persons to operate the unit.
Ensure that the safety precautions are observed!
To insert batteries -> Battery replacement
Warning:
With class 2 laser devices it is usual, in the event of an accidental brief
glance into the laser beam, for the eye to protect itself by the lid closure
reflex and/or by an natural reaction of turning away. If laser radiation
enters your eye, you should deliberately close your eyes and immediately
move your head away from the beam. Do not look into the direct or reflected beam.
The STABILA laser goggles available for our laser devices do not constitute 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 other operating or adjustment equipment is used than that specified here or if
the unit is operated in ways other than described here, this may result in hazardous
exposure to laser radiation.
• No manipulation (modification) of the laser unit is permitted.
• If the unit is dropped or subjected to strong vibrations it may malfunction.
• Always check that the unit is functioning correctly and accurately before you start work,
particularly if it has been exposed to heavy vibrations.
• Do not use in explosive or corrosive environments.
• Do not dispose of the batteries or unit with domestic waste.
• Keep this user manual in a safe place. If the laser unit is passed or sold on to another
person, ensure that the manual is included with the unit.

Place the laser unit in the appropriate working position
(vertical or horizontal). To start the laser, press button (3).
Holding this button for a longer period will switch the laser
o again. Activating the self-levelling function causes the
unit to level itself automatically. The laser beam does not (yet)
flash or rotate. Once levelling is completed, the beam stays
on constantly and begins to rotate. Fine adjustments can
still be made within the rst 30 seconds. These 30 seconds
are indicated by a slow flashing of the white LED (5).
If the unit is out of alignment by ≥ 5°, it is outside the
self-levelling range and cannot level itself automatically.
In this case the laser continues to flash.
The blue and green LEDs indicate which side of the unit is
too high. Adjust the unit by hand until the LEDs go out.
In vertical operation the device detects the alignment
automatically.

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.
When the tilt function is active, the white LED (5) is lit
steadily. If any event occurs that could result in the laser
unit being deflected from its exact alignment and setting,
the beam ceases to rotate and the blue (8) and green (9)
LEDs flash. If this occurs, check the laser unit and set it up
once again if necessary.
If the tilt function is triggered, this must be acknowledged
by pressing button (3) or, on the remote control unit, by
pressing buttons (17) + (20). Only aer this can you proceed
further.
The tilt function can be switched on or o in any mode
(touch button (3) briefly). When the laser unit is switched
on (button 3), tilt mode is always initially activated.
7. Tilt function
Deactivated tilt function
If the tilt function is deactivated (white LED flashing),
no warning is given of any change in the setting/alignment
in the event of interference. In automatic operation,
however, the unit re-levels itself automatically.

This mode is always set directly aer the unit is switched
on (button 3). Other modes can be selected by pressing
button (3) or button (4) or using the remote control unit.
In ‘Automatic’ mode the laser unit levels itself automatically.
Place the laser unit in the appropriate working position
(vertical or horizontal). To switch on, press button (3) once.
Now the LAR 350 is in ‘Automatic mode with tilt function’.
The automatic levelling process begins. Once levelling is
completed, the beam stays on constantly and begins to
rotate. Fine adjustments can still be made within the rst
30 seconds. These 30 seconds are indicated by a slow
flashing of the white LED (5).
When the tilt function is active, the white LED (5) is lit
steadily. If any event occurs that could result in the laser
unit being deflected from its exact alignment and setting,
the beam ceases to rotate and the blue (8) and green (9)
LEDs flash. If this occurs, check the laser unit and set it up
once again if necessary.
If the tilt function is triggered, this must be acknowledged
by pressing button (3) or, on the remote control unit, by
pressing buttons (17) + (20). Only aer 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’.

In some situations (e.g. when working on a shaking or
vibrating surface), the tilt function can be a hindrance.
With automatic relevelling, on the other hand, the unit
is readjusted each time it is knocked out of alignment.
Press button (3) x 2 = 1x switch on + 1x deactivate tilt function.
The white LED (5) flashes. The laser beam begins to rotate
once the unit has levelled itself.
When incidents occur that cause misalignment, the beam
ceases to rotate. 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).

9.1 Manual Operation with Tilt Function
In manual mode the laser plane is aligned by hand. Neither
self-levelling nor relevelling are active. The unit does not
level itself. If the tilt function is active, interferences
(shocks, vibrations) that could misalign the unit from its
exact original setting do not go unnoticed.
Place the laser unit in the appropriate working position
(vertical or horizontal). Press button (3) x 1 = switch on in
tilt mode. Press button (4) x 1 = activate manual mode.
The white LED (5) lights steadily. The blue (8) and green (9)
LEDs light steadily.
The laser beam rotates. Fine adjustments can still be made
within the rst 30 seconds. The laser plane can be set up by
direction-nding or by taking measurements.
If any event occurs that could result in the laser unit being
deflected from its exact alignment and setting, the beam
ceases to rotate and the blue (8) and green (9) LEDs flash.
If this occurs, check the laser unit and set it up once again
if necessary.
The inclinometer (available as an accessory) can be used to
aid setting up the inclination.
If the tilt function is triggered, this must be acknowledged
by pressing button (3) or, on the remote control unit, by
pressing buttons (17) + (20). Only aer this can you proceed
further.

9.2 Manual Operation without Tilt Function
In manual operation without tilt function, neither automatic
mode, 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 button (3) x 2 = 1x switch on +
1x deactivate tilt function. Press button (4) x 1 = Changeover
to/activate manual mode. The white LED (5) flashes. The

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 (14). 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.
Right angle (90°)
In vertical operation, the point laser and the
rotation plane form a 90° angle. This allows
right angles to be created.

The LAR 350 features an innovative remote control unit. It
allows a wide range of functions and settings to be intelli-
gently controlled. Settings are made by pressing the rele-
vant button while simultaneously rotating the remote con-
trol unit in the hand. Fine adjustments can then be made
while holding the unit in this way by touching the buttons
lightly. --> Buttons 21,22,23,24,25,26
The speed of adjustment of settings is determined by the
angle through which the unit is rotated.
To activate the functions of the highlighted buttons (20,21,22),
rst press the Shi button (17).
Activation of the Shi button (17) is indicated by the LED (18);
this is switched o aer about 30 seconds if no further button
is pressed.
The LED (19) indicates that the unit is transmitting.
The highest setting sensitivity is obtained by
operating the remote control unit while it is
horizontal in the longitudinal plane.
The unit can be adjusted to ensure a symmet-
rical response in the + and - directions. To
do this, place it on a level surface and hold
down buttons (21) and (22) simultaneously for
as long as the LED (19) flashes.

The rotation function is set when the unit is switched on and
can also be set at any time with button (25). In rotation mode
the laser beam rotates. By holding down button (25) and
simultaneously rotating the remote control unit the rotation
speed can be innitely adjusted up or down to 0 = point
function. This increases visibility.

In scan mode the beam does not rotate. Instead, it moves to
and fro rapidly between two points. The eye perceives this
as a laser line.
Button (24) switches the scan function on/o. When it is
switched on, the scan line is always located opposite
button (3) of the laser unit. The thickness of the laser line
can be innitely adjusted (thicker/thinner) by holding down
button (24) and rotating the remote control unit.
To rotate the scan line to the desired position, hold
down button (23) and rotate the remote control unit.

Briefly pressing button (21) = laser x-axis or (22) = laser y-axis
causes the rapidly flashing LEDs (blue or green) to indicate
the corresponding laser axis. The laser axes can be adjusted
independently through an inclination range of up to ±5°.
By using an inclinometer (available as an accessory),
this angle can be increased to about 50°.
Press the Shi button (17) to enable the inclination function
for the laser axes. The axis inclinations are varied by holding
down button (21) or (22) while rotating the remote control
unit. The corresponding LEDs flash during adjustment.

To enable the LAR 350 to perform vertical levelling and
marking tasks, it is placed on its side on the feet integrated
into the body. Position the unit so that the wording
‘VERTICAL MODE THIS SIDE UP’ appears on the top. The op-
erator display is then also at the top. The retaining bracket
(12) can be used to mount the LAR 350 on a tripod. The unit
switches into vertical mode automatically. All modes and
functions are available.
Note that in this position only the laser x-axis is automati-
cally levelled. The LEDs of the laser y-axis are lit.
