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.

Using the Optional 40-6391 Adjustable Trivet Stand: 1. When a laser is to be set on a flat surface where the laser beam is not centered in the pipe, use model 40-6391 Trivet Stand. 2. Using this system, the elevation of the laser beam can be set by either measuring down from a grade offset hub outside the trench or up from the floor of the manhole to the beam. The pipe laser can be fixed to the 40-6391 adjustable trivet stand as indicated by the picture below.

8. Self-Check & Fine Calibration IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. • Find a road, parking lot, or level plane (slope should be less than 4” at 100’/30m). • Pick 2 points (A and B) whose distance is about 100’ or 30m between each other. The distance does not need to be measured exactly, mark the 2 points. • Put the pipe laser behind point A, turn it on, and let it warm-up for 10 minutes. • Set the grade to be 00.000%.
PAGE 13
Accuracy Calibration • Set the grade at +0.01 - +0.02%. • Turn off the unit. • Press and hold “left arrow” and “right arrow” keys. • Press and release “power on/off” key when holding the “left arrow” and “right arrow” keys. • Hold the “left arrow” and “right arrow” keys until “mem clear” shows on the screen. • Recalibrate the laser until |(A2-A1) - (B2-B1)| is equal or less than 3mm. • When |(A2-A1)-(B2-B1)| is greater than 6mm, you need to contact a Johnson® authorized repair center. 9.
