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.

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.
C
Warning – Use of controls
or adjustments
performance of
procedures other than
those specified may result
in higher dosage of laser
exposure.
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.
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

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
60825-1:2001, CDRH 21 CFR
1040.10 and 1040.11.

Introduction 1
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 laser-
based 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
line, elevation, and grade control.
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.

Note – When installing the
batteries, ensure that you take note
of the positive (+) and negative (-)
diagram inside of the housing.
Note – The pipe laser has reverse
polarity protection. If the batteries
are put in wrong, no damage
occurs to the pipe laser but it does
not work. Allow it one minute to
recover after the batteries have
been installed correctly.
5 Put the top housing back on the

Smart Charger
The charger, to be used ONLY with the Ni-MH battery pack, starts
charging automatically as soon as a battery pack is installed and the charger
is plugged in. The LEDs on the charger indicate the condition shown in
Table 3.1.
Discharge Button: Pressing the
button for approximately 2 seconds
the charger automatically
discharges the battery and switches
over to charging. The process of
discharging the battery before
charging should be performed
every three months to help prevent
loss of battery capacity due to
frequent partly discharging.

2 Plug the battery recharger's
single-socket plug into the battery
pack's recharging receptacle.
3 Plug the battery recharger into
an appropriate outlet.
Note – The charger takes 10 hours
to charge the batteries to full
capacity.
Note – To extend battery life, the
charger discharge function should
be performed after every three
months of charging.

External Power Cable
P21 3.1.2
In case the internal batteries
become discharged and you do not
have spare batteries available, you
can also power the pipe laser using
an optional external power cable.
This can be achieved by using a
DC regulated automotive or
motorcycle battery with the
supplied optional external power
cable on some models. The internal
batteries will not recharge while
you’re using the external power
cable.
