6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Note:
Always check to be sure that the compensator lock/unlock switch
is in the locked position before removing and replacing batteries.
1. As shown in figure, open the battery cover.
2. Put three “AA” alkaline batteries into the
battery compartment noting polarity
3. Close the battery cover.
7. Using the Product
Place the laser on a relatively smooth, flat and
level surface.

8. Accuracy Check
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Horizontal line accuracy (horizontal)
1. Place unit on a tripod approximately 5′from a wall. Secure the
instrument on the tripod.
2. Face the front of the instrument to the wall, unlock the
instrument, and power on the horizontal and vertical laser lines.
Make a mark on the wall where the cross-line is displayed. Label
this as ‘A’.
3. Make a mark 8′from A, along the horizontal laser line, and label
as ‘M’.
4. Turn the instrument until the vertical line meets ‘M’, and then
make a mark 8′from ‘M’, and 15′from ‘A’. Label this mark as
‘B’. Also make a mark on the vertical line where it meets ‘B’.
5. Measure the height distance between ‘M’ and where the
horizontal laser line currently sits.
6. If e>1/16″, the instrument accuracy is out of tolerance, and
calibration is necessary.
Horizontal accuracy self-check (Vertical)
1. Stand up two straight poles/boards 15′ from each other, or two
walls which are parallel and more than 15′distance.
2. Place the instrument on the tripod, and place in the center of
the poles/boards/walls, and level the instrument by adjusting
the tripod.
3104i_Manuals 9/6/18 12:03 PM Page 14

©2018 Johnson Level & Tool - Rev. 2 15
3. Power on horizontal and vertical laser lines, and make a mark
where the cross laser meets target ‘A’. Mark this as ‘A1’.
4. Turn the instrument by 180°, so that the cross line meets target
‘B’. Mark this as ‘B1’.
5. Move the tripod within 2′of target ‘A’. Make a mark where the
cross meets target ‘A’, and label as ‘A2’.
6. Rotate the instrument by 180° and make a mark where the cross
meets target ‘B’, and label as ‘B2’.
7. Calculate (A1-A2)-(B1-B2) = E. If the absolute value of E is above
1/16″, the instrument accuracy is out of tolerance and calibration
is required.
Dot Accuracy
1. With the laser on its base and set on a flat platform, turn the
laser on.
2. Mark the down beam location and use this as your reference
point.
3. Locate the up beam and mark its point as ‘A’.
4. Rotate the laser (not moving the base) 180° by swiveling the laser
on its base and mark the up beam location as ‘B’.
5. Rotate the laser 90° and mark the up beam as ‘C’.
6. Rotate the laser 180° and mark the up beam as ‘D’.
Note: Do not move the base, and always have the down beam in
the same location.
7. Connect the four dots. Connect A to B, and C to D.
8. If the center point ‘E’ is more than 1/8″at 50′, or 1/16″at 25′
from points A, B, C, and D, the unit needs to be recalibrated.

Checking the 3 Horizontal Beams
1. As shown in Fig. 1, set the instrument on a tripod or flat platform
50′from an upright wall. Aim the front beam at the face of the
wall. Mark the point projected on the wall by front beam as ‘A’.
2. Turn the instrument clockwise (Fig. 2) to make the point
projected by the right laser beam on the same exact line as point
‘A’, and then mark the point as ‘B’.
3. Turn the instrument clockwise (Fig. 3) to make the point
projected by the left laser beam on the same exact line as point
‘A’, and then mark the point as ‘C’.
4. The vertical distance between points A, B and C should not
exceed 0.125″(3.2mm).
5. If laser exceeds 1/8″at 50′, contact Johnson Level & Tool for
service.

the beam detectable,
but dimmer
Batteries are weak
Improper battery type
Turn off pulse mode by
pressing “P” button until
line LED’s are solid
Replace batteries
Ensure high quality
Alkaline batteries are
used
Laser can not be
detected with a detector
(Note: detector is sold
separately)
Pulse mode may be off
Detector may require
new batteries
The detector may not be
the proper one for the
product
Trying to detect dot
lasers when dot laser
beams are not
detectable; only the
lines are detectable
Turn on pulse mode by
pressing “P” button until

Validate detector is for
lines of the appropriate
wavelength
Do not attempt to detect
the dot laser, use the
line laser if possible
