Thank you for purchasing this JLX 180° crossline
laser. JLX tools are Johnson’s professional tools,
designed to help you 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 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 off 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 off each individual laser by pressing
for the horizontal beam and/or
for the
vertical beam. If you do not need both beams
for your work, disabling the unneeded beam
significantly 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.
