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 IIIa laser tool and is manufactured to comply with CFR 21, parts 1040.10 and
1040.11 as well as international safety rule IEC 285.
