Class A digital device, pursuant to Part
15 of the Federal Communication
Commission (FCC) rules. These limits
are designed to provide reasonable
protection against harmful interference
in a commercial environment. This
equipment generates, uses, and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instructions, may cause
harmful interference to radio or
television communication. However,
there is no guarantee that interference
will not occur in a particular
installation. If this equipment does
cause harmful interference to radio or
television reception, which can be
determined by turning the equipment
off and on, the user is encouraged to try
to correct the interference by one or
more of the following measures:

– Reorient or relocate the receiving

antenna.

– Increase the separation between the

equipment and the receiver.

– Connect the equipment into an

outlet on a circuit different from that
to which the receiver is connected.

– Consult the dealer or an experienced

radio/TV technician for help.

Changes and modifications not
expressly approved by the
manufacturer or registrant of this
equipment can void your authority to
operate this equipment under Federal
Communications Commission rules.

Safety Information

For detailed installation and operating instructions, follow the instructions
given in this manual for this laser.

Laser Safety 0.0.1

The maximum radiant power
output of this laser is less than
5 mW. Use only the targets
supplied with this product.

Controls are listed on the radiation
control drawings.

Warning – Use of controls

C

To help you comply with your
government regulations, a laser
safety kit is supplied with every
laser. This kit contains operator
qualification cards and a sign that
should be posted near the laser
whenever it is in use.

or adjustments
performance of
procedures other than
those specified may result
in higher dosage of laser
exposure.

As with any visible laser device,
observe the following safety rules:

• Never look directly into a laser
beam or point the beam into the
eyes of others. Set the laser at a
height that prevents the beam from
shining directly into people’s eyes.

• Do not remove any warning
signs from the laser.

• Make sure that only properly
trained people use this product.

• If service is required, which
results in the removal of the outer
protective cover, factory-trained
personnel must perform this.

Certification 0.0.2

The IEC and the United States
Government Center of Devices for
Radiology Health (CDRH) has
classified this laser as a Class
3R/3A laser product. This laser
complies with IEC/EN

Thank you for choosing from the
Trimble family of precision pipe
lasers. You’ve just made a wise
investment in field-proven products
made by Trimble, the world’s
leading manufacturer of laser­based leveling, alignment, and
grade-control systems.

The pipe laser is an easy-to-use
tool that provides underground
contractors line, elevation, and
grade control for installing storm,
sanitary, or other gravity-flow pipe.
This system can also be used for
tunneling, boring, pipe alignment,
or any other application requiring

The pipe laser projects a highly
visible red beam of laser light in a
direction at a predetermined
(grade) for the alignment of
gravity-flow pipe. The laser light is
intercepted by a target. To align the
pipe, you need to position it so that
the pipe laser’s beam is centered in
the target.
