Pipe Laser
Model No. 40-6690
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.

Grade enter button
After the desired grade has been entered on the LCD, press the grade
enter button. The laser beam will move to the new grade value.
When the laser is self-leveling, the grade value symbol will flash and
will stop flashing when the laser is level.
Out of level alarm (Front and back)
f the laser is placed beyond its self-leveling range, the laser beam
will blink and the LCD symbol will blink. The laser will need to be
repositioned within its self-leveling range as noted below.
When LCD shows: user needs to lower the
handle side.
When LCD shows: user needs to raise the
handle side.
Out of level (right and left)
The LCD has a bubble symbol which is used to indicate the right or
left out of level status. f the laser is out of level to the right or left,
it will effect its accuracy. Place the laser so the bubble symbol is
centered.
f the LCD symbol flashes, it means the left side of laser is beyond
the allowed range and the left side needs to be lowered.
f the LCD symbol does not flash, it means the left side of laser is
high but still in the allowed range.

This symbol means the laser is level and is in its idea accuracy
and working status.
f the LCD symbol does not flash, it means the ride side of laser is
high but still in the allowed range.
f the LCD symbol flashes, it means the right side of laser is
beyond the allowed range and the right side needs to be lowered.
Battery symbol
With the laser powered on, check the battery capacity symbol to note
the power status on the LCD display.
Full battery, no need to charge
Low battery, laser can be used
No power, battery pack needs to be recharged or new
alkline batteries must be installed
Remote function
ncluded with the pipe laser is a remote control. The keypad function
of the remote control is the same as the pipe laser, except the power
button .
• Press the power button on the remote when pipe laser is turned on
and the pipe laser will enter the sleep mode. The pipe laser saves

8. Self-Check & Fine Calibration
IMPORTA T: t 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%.
• Point the laser beam to go through points A and B, make sure the
laser is in its self-leveling range.
• Accurately measure the height from the center of the laser beam
point A and point B, note it as A1 and B1.
• Put the laser behind point B and let the laser beam go through
points A and B making sure the laser is in its self-leveling range.
4429H-English_Manuals 2/18/11 9:40 AM Page 17

18 ©2011 Johnson Level & Tool
• Accurately measure height from the center of the laser beam to
point A and point B, note it as A2 and B2.
• Calculate A2-A1, B2-B1. f |(A2-A1) - (B2-B1)| is less than or equal
to .118” or 3mm, the accuracy is good;
f the value of A2-A1 is larger than the value of B2-B1, the
laser beam is too high, and the user needs to adjust the
laser line to be leveled.
f the value of A2-A1 is smaller than the value of B2- B1,
the laser beam is too low, and the user needs to adjust
the laser line to be leveled.
Accuracy Calibration
• Press the power and enter buttons simultaneously, then release the
power button first. When the LCD shows “CAL BRATE...” release
the enter button then the laser will enter the calibration mode.
Sliding the cover down on the remote control, press the up and
down buttons on the remote, to control the laser beam movement
up or down. f the laser beam is too high, press the down button.
f the laser beam is too low, press the up button. Press the enter
button (on the remote control) to confirm the calibration.
• 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.
