Main components

The STABILA LA-4P laser is an easy-to-use four-point laser for horizontal and vertical

levelling and plumb lines. This simple-to-use tool allows you to transfer points

between the floor and ceiling and to establish 90° points for laying out wall lines

and putting up wall partitions. You can also use the laser for other applications

where true plumb, square, and level setups are required.It is self-levelling in a

range of ± 4°.

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

Green LED: Operating mode ON or READY / OK

1/4" threaded connector for tripod

Getting started

Please note that if the laser beams are to travel through glass or other transparent

materials, this can adversely affect the laser's accuracy

Press the power button.The green power-status LED lights to show that the laser

is on.

Setting Up the Laser and Transferring a Point

Locate the position of the up beam and level beam.

Make a mark on the ceiling and wall respectively.

Adjust the position of the laser so that the down beam is on

the control point.

Place the laser so that the bottom feet are on the front edge of the bottom

track.

Plumbing a Wall

Please note that the centre of laser dot is marked!

Place the laser on a flat surface.The laser must be within ±4° of being level for it to

self-level.

Holding down the ON / OFF key for 3 seconds activates automatic switch-off

after 60 minutes.

Tip:

Place the adapter with the centring feet in the drill hole.

The drill hole point can now be perpendicularly transferred quite easily.

Slide the lock in the direction of the arrow. The centring feet now centre

the adapter precisely in the drill hole.

With the adapter, you can easily perpendicularly transfer the centre points

for drill holes with diameters of 50mm (1,96”) to 115 mm ( 4,72”).

Transferring drill hole points :

Adjust the top of the partition until the up beam is on the front edge of

the top track.

Switch the unit on ( button 1)

Checking plumblining

Locate the position of the up beam

on the ceiling and make a mark.

Locate the position of the up beam on

the ceiling, which will be twice the

actual error, and make a mark.

Measure the difference between the two

marks on the ceiling, which will be twice

the actual error.

The difference may not be greater than:

6mm in 7.5 m (3/16“ in 25 ft),

Rotate the laser 180° and realign the

down beam over the reference mark

on the floor.

Place the laser so that its down beam

is over a reference markon the floor.

Switch the unit on ( button 1)

The LA-4P four-point 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.

Checking the calibration

Horizontal checking

Mark the position of the visible laser dot on the wall (point 2).

Mark the position of the visible laser dot on the wall (point 1)

Switch the unit on ( button 1)

Set the four-point laser on a flat surface, or mount it on a tripod, at a distance

of 50 to 75mm ( 1,96” to 2,95”) from a wall A, with its front sidefacing the wall.

Turn the complete unit 180° without altering the height of the laser.

Two parallel wall surfaces at least 6m ( or 20 ft) apart are required for the

horizontal check.

Without changing the height of the laser, rotate it 180° to place the beam near

the markon the first wall (step 3 / point 1 ).

Measure the vertical distance between the

beam and the markmade in step 3.

The difference may not be greater than:

Measured Value

Now move the unit directly in front of wall B

Set the unit's height so that the laser dot's height matches that of point 2.

1. Find a room at least 10 m (35 ft) long.

Mark a point (A) on the floor at one end

of the room.

2. Set up the laser so that its down beam

is over point A. Make sure the level

beam points toward the far end of the

room.

3. Mark a point (B) on the floor at the

center of the room using a target to

transfer the level beam location to the

floor.

6. Markthe location of the square beam

(D) on the floor.

Turn the LA-4P 90° so that the level beam aligns with point D.

Mark the location of the square beam (E) on the floor as

close as possible to point A.

Measure the distance between points A and E.9.

5. Move the LA-4P to point B and align

the level beam to point C again.

4. Mark a point (C) on the far wall or trans-

fer the level beam location to the floor.

To ensure accuracy, the distances from A to B, B to C,

and B to D should be equal.

Tip:

Room length or distance between

points A and C The 90° angle between the level beam

and square beam is out of calibration if

the distance between points A and E is:

10 m (35 ft)

20 m (70 ft)

Checking Level to Square Beam 90° Calibration

Replacing the batteries

Slide the battery cover (4) in the direction of

the arrow and insert new batteries in

accordance with the symbols in the battery

compartment.

4 x 1,5V

alkaline mignoncells,

size AA, LR6

Tip:

Remove the batteries if the unit will not be used for a long period !

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

reaction to turn one's head. This

equipment can therefore be used

without additional protective measu-

res. Nevertheless, you should not look

directly into the laser beam. The laser goggles enclosed with these

units are not safety goggles. They are desi-

gned to make the laser light easier to see.

Do not let the unit fall into children's

hands!
