Johnson 40-6650 User manual

Thank you for purchasing this Johnson crossline
laser. Lasers are the easiest way to lay out your
jobsite, helping you to work faster, safer and smarter.
ATTENTION:
• Read all instructions before operating this tool. Do not
remove any labels from the tool.
• Do not project the laser into the eyes of others.
• Do not set up the laser tool at eye level, or operate
the tool near reflective surfaces, as the beam can be
projected into your eyes or the eyes of others.
• Do not place the laser tool in a manner that may cause
someone to unintentionally look into the laser beam.
Serious eye injury may result.
• Do not operate the tool in explosive environments (i.e.,
in the presence of gases or flammable liquids).
• Keep the laser tool out of the reach of children and
other untrained persons.
• Do not attempt to view the laser beam through optical
tools such as telescopes - serious eye injury may result.
• Always turn o the laser tool when not in use or when
left unattended for any period of time.
• Disassembly or repair by unqualified persons will void
the warranty.
• Insert batteries. See INSTALLING BATTERIES.
• Install the laser on a tripod, the included magnetic
wall mount bracket or other stable surface.
• Unlock the pendulum to use in self-leveling mode.
Lock the pendulum to use in manual mode. See
UNLOCKING THE PENDULUM. In manual mode,
the TILT LED will illuminate to alert you to that
the laser is not self-leveling.
• Power on or o each individual laser by pressing
. The laser will toggle between illuminating the
horizontal beam, vertical beam, both beams and
powering o. Disabling a laser you are not using
extends the life of the battery.
• Press at any time to enable pulsed operation,
which makes the beam detectable by compatible
laser detectors. The PULSE LED will illuminate
when in pulse mode.
Note: For information about laser detector
compatibility and operation, contact Johnson or
your local Johnson dealer.
• When you have completed your work, lock the
laser pendulum and store the tool in its provided
case.

40-6650/40-6651/40-6657 v2
H/V: Toggles between horizontal
beam, vertical beam, both and o.
PULSE: Enables pulse mode, so the
laser can be used with a detector.
SAFETY INFORMATION
The pendulum lock secures the laser during
transport to prevent damage to the self-leveling
mechanism. It also enables the laser to be used at
any angle in manual mode. To lock the pendulum,

• 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.

CHECKING ACCURACY
PLUMB ACCURACY:
• Position laser at P110’
from a doorway.
• Mark beam at P1.
• Mark point P220ft away.
• Mark points C on the
floor under doorway and
D on top of doorway.
• Move laser to P2. Aim through C and P1. 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 A1.
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 A1and
A2. If this distance is smaller than 1/8” at 20’, your
laser is properly calibrated.
NOTE: If your laser needs calibration or service,
return it to a Johnson authorized service center for
repair.
4: Rotate laser 180°.
Mark beam height on
Wall A as A2.
*Battery life as tested with Lithium AA / Alkaline AA
batteries, and all beams enabled.
