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.

1.  Press the power button. The green power-status LED lights to 

show that the laser is on.

  CAUTION: Never look directly into the laser beam.

2.  Place the laser on a flat surface. The laser must be within ±4° of 

being level for it to self-level.

3.  Adjust the position of the 

laser so that the down beam 
is on the control point.

4.  Locate the position of the 

up beam and level beam. 
Make a mark on the ceiling 
and wall respectively.

1.  Place the laser so that the 

bottom feet are on the front 
edge of the bottom track.

2.  Press the power button.

3.  Adjust the top of the 

partition until the up 
beam is on the front edge 
of the top track.

You will get years of service from your laser by following the 
maintenance and care recommendations in this manual. However 
well the product is designed, mishaps do occur and the most 
common problems associated with these are covered in the 
following areas. Any damage to the laser caused by improper 
maintenance and care voids the warranty.

When transferring the laser from a very low temperature to a 
warmer environment or visa versa, always allow time for the laser 
to reach the new temperature before using. Allowing this time is 
especially important when transferring the laser from an extremely 
heated/cold vehicle to the job site.

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 
the laser and its lenses.

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

CAUTION: Do not submerge the laser.

When you’re not using the laser, store it in its pouch/carrying case.

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.

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