Instruction Manual
Congratulations on your choice of this Pipe Laser. We suggest you read
this instruction manual thoroughly before using the pipe laser. Save this
instruction manual for future use.
The 40-6690 pipe laser is an easy-to-use laser that provides underground
contractors line, elevation, and grade control for installing storm, sanitary, or
other gravity-flow drainage 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 emits 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 at the opposite end of the pipe by the pipe laser target. To align
the pipe, position it so that the pipe laser’s beam is centered in the target.
This is a Class a laser tool and is manufactured to comply with CFR 21,
parts 1040.10 and 1040.11 as well as international safety rule EC 285.
