• 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 UNLOCKING THE PENDULUM.
• 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.

10’
from a doorway.
• Mark beam at P
1.
• Mark point P
2
20ft away.
• Mark points C on the
floor under doorway and
D on top of doorway.
• Move laser to P
2
. Aim through C and P
1
. Mark
point E next to D.
• If the distance D to E <
1
/
16
” for a 10’ doorway,
your plumb laser is properly calibrated.
1: Set laser next to Wall
A. Mark beam height on
Wall A as point A
1.
Check accuracy using two walls 20’ apart.
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.
5: Measure the vertical distance between A
1
and
A
2
. If this distance is smaller than
1
/
8
” at 20’, your
laser is properly calibrated.
