STABILA LAR 160 G Rotary Laser

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.

Safety instructions for laser units

In Class 2 laser units, your eyes are usually protected from accidental, short-term exposure 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 specified 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 off. 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.
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.

 Operating mode

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”.

 Automatic operation with relevelling

In some working conditions (where shocks or vibrations affecting 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.

 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-finding 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”.

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.

 Checking Accuracy

The STABILA LAR 160/ LAR 160 G rotation laser has been designed for construction sites and has left 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.

• Horizontal check
• Vertical check

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).

Repeat steps 4 and 5 twice to obtain points 3 and 4. If the differences 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 100ft). Here points 1 and 3 correspond to the unit’s x-axis and points 2 and 4 to its y-axis.

Vertical check

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.
    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”).
