Introduction

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.

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

4. Locate the position of the

up beam and level beam.

Maintenance and Care

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.

Handling Precautions

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.

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
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.

Storage

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.

Battery Disposal

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