Using the Target
The target can be used for multiple pipe sizes. It features
a unique design: the target panel is mounted at the front
of the base, not in the center. This allows you to view
it easier at the front of the pipe. It also has a magnetic
base for attaching to trench box side wall after pipe set-
ting for better airflow, to minimize refraction.

Basic Set-up And Operation
The steps noted below are illustrated in previous sections. See next section for specific applica-
tions.
1. Attach any mounting accessories to the unit, such as the legs, trivet, handle/rod mount,
etc. Place it in the manhole or pipe at the proper offset and elevation.
2. Power-up the laser. Swivel it left or right so that the cross axis is level. Check the vial on
the LCD (see p. 3). Set the desired grade.
3. Adjust the target plate to the correct pipe diameter. Place the target in the opposite end
of the pipe and level it using the vial.
4. Adjust line to the center of its range with the remote by pressing the centerline button
or by pressing both line adjust buttons simultaneously. Use the remote to align the
beam to the target.
5. Lift pipe up or down until beam is in the middle of the target bull’s-eye; the pipe is
then on line and at the desired slope.
