8. Self-Check & Fine Calibration

IMPORTANT: It is the responsibility of the user to verify the

calibration of the instrument before each use.

Horizontal Accuracy (transversely)

1. Locate a wall, set up an elevated tripod 15 feet away from the wall, fix the laser to the tripod.

2. Rotate the laser until the V1 laser beam faces the wall and power on all the laser lines, mark the cross dot of V1 and H on the wall as point “A”.

3. Rotate the laser 90º counter-clockwise and mark the cross dot of V2 line and H line as “B”.

4. Measure the distance ‘e’ between “A” and “B”. (See illustration below)

5. If the distance is greater than 3mm (0.125"), then the horizontal line accuracy is out of tolerance and the laser needs to be calibrated.

When the horizontal line accuracy is out of

tolerance, remove the screw of the self-calibration port. Use a 3mm hex wrench to adjust the laser to get a distance ≤3mm.

SelfCalibration Port

8369H-English_Manuals 10/2/14 10:19 AM Page 11

Horizontal Accuracy (longitudinal)

1. Set up two grade rods which are 15 feet away from each other as seen to the right (or two parallel walls which are more than 15 feet away from each other.)

2. Mount the laser on a tripod 15 feet away from the left grade rod, level out the bubble by adjusting the tripod.

3. Power on the laser, mark the cross dot of V1 line and H line on the grade rod as “C”.

4. Rotate the tripod 180º, mark the cross dot of V2 and H as “D”.

5. Move the tripod 15 feet away from the right grade rod. Line up the cross dot with point “D” by elevating the tripod.

6. Rotate the laser 180º, measure the distance between the new projected cross dot and point “C”.

7. If the distance is greater than a 3mm (0.125"), the horizontal accuracy of the laser is out of tolerance and the laser needs to be calibrated.

When the horizontal accuracy is out of

tolerance, remove the screw of the self-calibration port. Use a 3mm hex wrench to adjust the weight inside the laser to make the distance ≤3mm

SelfCalibration Port

Note: If you could not calibrate the accuracy through the self-calibration port, please send the instrument to Johnson Level for service.

15. Trouble Shooting

• If the unit does not turn on, check the battery polarity or clean battery terminals and install new alkaline batteries.

• If the laser does not illuminate, check the battery polarity or clean battery terminals and install new alkaline batteries.

• If the unit is out of calibration less than 1/4" at 50', follow calibration procedure in manual.

• If the unit is out of calibration more than 1/4" at 50', contact an authorized Johnson service center or Johnson Level & Tool's customer service department.

• If the unit will not calibrate, contact an authorized Johnson service center or Johnson Level & Tool’s customer service department.

• If the unit beeps and/or flashes constantly, check to see if the unit is being tilted to angles beyond the self-leveling range. If the unit is being used for a level application, place onto a surface that is within the self-leveling range. If it is still beeping and/or flashing, the unit is out of calibration.

• If the unit turns off after a short time, clean the battery terminals and install new alkaline batteries. Also, make sure that the on/off knob is in the on position
