User Guide

Thank you for choosing the LP20 or LP40 Spectra Precision®
Laser from the Trimble® family of precision hand-held lasers. 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.

Before using the laser, be sure to read this operator’s manual
carefully. Included in it is information about setting up, using,
and maintaining the laser. Also included in this manual are
CAUTIONS and Notes. Each of these words represents a level
or danger or concern. A CAUTION indicates a hazard or unsafe
practice that could result in minor injury or property damage.
A Note indicates important information unrelated to safety.

Your comments and suggestions are welcome; please contact us at:

System Cleaning

For maximum performance and accuracy always keep the lenses
clean. When cleaning, apply very light pressure and use only a
good quality glass cleaner on a soft cloth to clean the exterior of

maintenance and care voids the warranty.

CAUTION: A dry cloth or abrasive organic cleaner could scratch
or damage these surfaces.

Handling Precautions

CAUTION: Do not submerge the laser.

When transferring the laser from a very low temperature to a
warmer environment or visa versa, always allow time for the laser

CAUTION: 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.

CAUTION: The batteries should be removed when storing the
laser more than 30 days.

Battery Disposal

Some states and local areas have regulations regarding the disposal
of batteries. Be sure to dispose of discharged batteries properly.

Calibration

Checking Accuracy—Level

Before each use, be sure to check the pocket laser for signs of
damage. If the laser has been dropped or subjected to other rough
treatment, it should be checked for accuracy.

Checking Accuracy—Plumb

1. Press the power button.

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.

Checking Level to Square Beam 90° Calibration
(LP40 only)

Refer to the graphic for the location of the LP40 at each step and
for the location of the marks made at each step. All marks can be
made on the floor by placing a target in front of the level or square
beam and transferring the location to the floor.

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

4. Mark a point (C) on the

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.

6. Measure the difference
between the two marks on
the ceiling, which will be
twice the actual error. If
the difference is more than
5 mm in 7.5 m (

in 25 ft), the laser must be
serviced at an authorized
service center.

5. Move the LP40 to point B and align the level beam to point
C again.

6. Mark the location of the square beam (D) on the floor.

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

and B to D should be equal.

7. Turn the LP40 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. If the
measurement is greater than the values shown below, the laser
must be serviced at an authorized service center.

Room length or distance The 90° angle between the
between points A and C level beam and square beam is out

1. In an area with at least 6 m (20 ft) between two parallel walls,
place the laser 50–75 mm (2–3 in.) from one wall, facing
the wall.

2. Press the power button.

3. Locate the position of the level beam on the wall and make
a mark.

4. Rotate the laser 180° so that the laser faces the other wall.

5. Locate the position of the level beam on the wall and make
a mark.

6. Move the laser to the far wall, facing the wall.

the mark made in step 5.

8. Without changing the height of the laser, rotate it 180° to place
the beam near the mark on the first wall (step 3).

9. Measure the vertical distance between the beam and the mark

Laser Safety

The pocket laser uses a Class 2 laser, which complies with the
requirements based on the IEC825-1/EN60825 standards (Class
2 based on 21CFR 1041). This laser may be operated without the
need for any additional protective measures. Nevertheless, as with
the sun, care should be taken to avoid looking directly into the
light source.

CAUTION: Never look directly into the laser beam.

Please keep the pocket laser out of the reach of children.
