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 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.

Page 7

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. Loosen the elevating lock knob to adjust the height, loosen the TILT lock knob to adjust the TILT angle.

Laser Placement with leg sets:

Choose the different size leg sets for different size pipe. (6” or 150mm (no legs), 8” or 200mm, 10” or 250mm, 12” or 300mm, 15” or 400mm, 21” or 500mm).

For 3 feet support of the pipe laser:

Screw the silver adapter to the hole under the handle of the pipe laser. Attach one leg to the adapter and two legs to the front of the pipe laser as shown in picture.

LCD backlight and LED button

Power on the laser and press the LCD/LED button . The top green LED will turn on. The line-axis pivot marker and LED identifies the pivot point for the pipe lasers line system. The LED also allows you to align a transit over the top of the pipe laser.

Page 9

Left and Right line control buttons

With the laser powered on, press the left line control button to move the laser beam to the left and press the right line control button to move the laser beam to the right. The speed of the line movement increases as the line control button is held.

When the laser dot is moving, the LCD display will show the relevant laser dot position. A *---- symbol flashing means the laser dot is as far left as it can go. A -*--- symbol means the laser dot is on the left A --*-- symbol means the laser dot is centered A ---*- symbol means the laser dot is on the right A ----* symbol flashing means the laser dot is as far to the right as it can go.

Center position

After the laser is turned on, pressing the left and right control buttons simultaneously for one second, will reset the laser line to the center position.

• When the dot is moving to the center position, the LCD will display the following symbol.

• When the laser dot is centered, the LCD will display the following symbol.

--*--

Grade setting position button

Turn the laser on by pressing the power button. The laser will move to the last entered grade. Press the set button and the (+) or (-) symbol on the LCD will blink. Pressing the set button again will make the first digit blink. Each additional press of the set button will make the next digit to the right blink. When the last digit is blinking and the set button is pressed again, the (+) or (-) symbol will blink.

Grade increase or decrease buttons

In the grade setting mode, with the desired digit blinking, change the grade value by pressing these buttons. Press the up button to increase the value of the digit. Press the down button to decrease the value of the digit. Holding the button in will change the value quickly.

Holding the together will set the grade value to “0”.

Page 10

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)

If 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. If 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.

If the LCD symbol flashes, it means the left side of laser is beyond the allowed range and the left side needs to be lowered.

If 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.

If the LCD symbol does not flash, it means the ride side of laser is high but still in the allowed range.

If 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 alkaline batteries must be installed

Remote function

Included 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 the current data and powers down.

• The laser beam will be off in the sleep mode and the top LED will flash slowly. Press

the power button on the remote again and it will power up the laser. If the laser is in the sleep mode for more than 30 minutes, it will power off automatically.

• Remote range: front (laser output window end) 165’ or 50m, back (handle end) 35’

or 10m.

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%.

• 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.

• 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. If |(A2-A1) - (B2-B1)| is less than or equal to .118” or 3mm,

the accuracy is good;

If 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.

If 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.

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.
