GB Operating instructions 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: 0049 / 63 46 / 3 09-470

Getting started Press the power button. The green power-status LED lights to show that the laser is on.

Holding down the ON / OFF key for 3 seconds activates automatic switch-off after 60 minutes. Place the laser on a flat surface. The laser must be within ±4° of being level for it to self-level.
Tip: Please note that if the laser beams are to travel through glass or other transparent materials, this can adversely affect the laser's accuracy
Setting Up the Laser and Transferring a Point Adjust the position of the laser so that the down beam is on the control point. Locate the position of the up beam and level beam. Make a mark on the ceiling and wall respectively. Please note that the centre of laser dot is marked!
Plumbing a Wall 1. Place the laser so that the bottom feet are on the front edge of the bottom track. 2. Switch the unit on ( button 1)
D
Illuminated green LED -> laser in operation 3. Adjust the top of the partition until the up beam is on the front edge of the top track.

Transferring drill hole points : 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”).
C
1. Place the adapter with the centring feet in the drill hole.
F
2. Slide the lock in the direction of the arrow. The centring feet now centre the adapter precisely in the drill hole. 3. The drill hole point can now be perpendicularly transferred quite easily.

Checking the calibration 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 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-levelling range.
Checking plumblining 1. Switch the unit on ( button 1) 1
2. Place the laser so that its down beam is over a reference mark on the floor.
3. Locate the position of the up beam on the ceiling and make a mark. 4. Rotate the laser 180° and realign the down beam over the reference mark on the floor.
5. Locate the position of the up beam on the ceiling, which will be twice the actual error, and make a mark.
< 6mm
< 3 /16”
6. 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), 7,5m / 25 ft
12
Horizontal checking Two parallel wall surfaces at least 6m ( or 20 ft) apart are required for the horizontal check. 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. 2. Switch the unit on ( button 1)

3. Mark the position of the visible laser dot on the wall (point 1)
I
4. Turn the complete unit 180° without altering the height of the laser.
K
5. Mark the position of the visible laser dot on the wall (point 2). 6. Now move the unit directly in front of wall B
L
7. Set the unit's height so that the laser dot's height matches that of point 2. 8. Without changing the height of the laser, rotate it 180° to place the beam near the mark on the first wall (step 3 / point 1 ). Measure the vertical distance between the beam and the mark made in step 3. The difference may not be greater than:

M
Checking Level to Square Beam 90° Calibration 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. 4. Mark a point (C) on the far wall or transfer the level beam location to the floor.
5. Move the LA-4P to point B and align the level beam to point C again. 6. Mark the location of the square beam (D) on the floor. Tip: To ensure accuracy, the distances from A to B, B to C, and B to D should be equal. 7. Turn the LA-4P 90° so that the level beam aligns with point D. 8. Mark the location of the square beam (E) on the floor as close as possible to point A. 9. Measure the distance between points A and E. Room length or distance between The 90° angle between the level beam points A and C and square beam is out of calibration if the distance between points A and E is: 10 m (35 ft) 20 m (70 ft)
> 9,0 mm (3/8 inch) > 18,0 mm (3/4 inch)

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 !
Recycling programme for our EU customers: In accordance with the WEEE regulations, STABILA provides a disposal programme for electronic products at the end of their service life. For more details, please contact: www.STABILA.de / Recycling or: 0049 / 6346 / 309-0
NB: In Class II laser equipment, your eyes are protected from accidental, shortterm 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 measures. Nevertheless, you should not look directly into the laser beam. Do not let the unit fall into children's hands!
EN 60825-1 : 03 10
The laser goggles enclosed with these units are not safety goggles. They are designed to make the laser light easier to see.

Care and maintenance • Dirty lens glass on the beam emitter detracts from the quality of the beam. It should be cleaned with a soft cloth. • Clean the laser unit with a damp cloth. Do not spray or immerse the unit! Do not use solvents or thinners! The LA-4P four-point laser must be handled carefully, in the same way as any precision optical instrument.
Tip: The laser unit should be allowed sufficient time to adjust to the ambient temperature before you start it up. For example, when the laser is brought from an extremely hot / cold vehicle onto the building site. When you’re not using the laser, store it in its pouch/carrying case. Do not store the laser in a wet pouch/carrying case. If the pouch/carrying case gets wet, let it dry before storing the laser in it.
Do not submerge the laser.
