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 180° on its base, realigning the down beam
(reference point) and mark the up beam as point '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:
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 <1/8" at 50' or 1/16" at 25' from points
A, B, C and D, accuracy is within specification
1. As shown in Fig. 1, set the laser 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 laser 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 laser 180° (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 1/8".
5. If distances between points A, B and C is <1/8" at 50',
accuracy is within specification.
• Tool does not power on or remain on:
Replace batteries.
Check battery polarity.
• Laser flashing or emitting audible tone:
Laser is outside
of its self-leveling range.
• Battery light flashes, laser appears dim:
The batteries
have depleted. Replace or recharge the batteries.
• Laser does not self-level:
Unlock the pendulum.
See PENDULUM LOCK.
• Laser is not detectable by a laser detector:
Ensure pulse
mode is enabled. Ensure the detector is compatible with the
laser’s wavelength and is meant to detect pulsed laser lines.
Contact Johnson or your local Johnson dealer for help in
choosing a suitable laser detector to use with your laser.

HORIZONTAL LINE ACCURACY:
Check accuracy using two walls 15' apart.
1:
Set laser next to Wall A.
Mark beam height on
Wall A as point A1.
2:
Rotate laser 180°.
Mark beam height on
Wall B as point C.
3:
Set laser next to
Wall B and adjust beam
to height C.
4:
Rotate laser 180°.
Mark beam height on
Wall A as A2.
5:
Measure the vertical distance between A1 and A2.
If this distance is <1/16" at 20', your
horizontal accuracy is within specification.
NOTE:
If your laser needs non-warranty service or calibration,
return it to a Johnson authorized service center for repair.

PLUMB LINE ACCURACY
:
• Position laser at point 1 10' from a doorway.
• Mark beam at point 1.
• Mark beam at point 2 20' away.
• Mark points C on the
floor under doorway
and D on doorway.
• Move laser near point 2.
Aim the beam through
point 2, C and point 1.
Mark point E next to D
on doorway.
• If the distance D to
E <1/16" for a 10' doorway,
your plumb accuracy
is within specification.
