2. Features and Functions
• Projects up to three laser beams simultaneously to plot both
crosslines and a plumb line, or either line individually.
• Tilt mode can be used to plot orthogonal reference lines at
any angle.
• Magnetically dampened compensator system stabilizes the
pendulum quickly and accurately, and stays level even with
nearby jobsite vibration.
• Status light alerts you to when the tool is beyond its leveling
range.
• Locking mechanism protects the pendulum during transportation.
• 1/4″-20 tripod thread for use with most common tripods.

• Do not set up laser tool at eye level or operate the tool near a reflective surface as
the laser beam could be projected into your eyes or into 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 as
serious eye injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the batteries when storing the tool for an extended time (more than 3 months)
to avoid damage to the tool should the batteries deteriorate.

6. Operating Instructions
IM ORTANT: t is the responsibility of the user to ensure proper
maintenance of the Self-Leveling Cross and Line Laser. Conduct
periodic test measurements to ensure the instrument is measuring
accurately and consistently. This is most important if the
instrument has been exposed to extreme temperatures or
moisture. Keep the Self-Leveling Cross and Line Laser optic lens
clean and inspect for damage.
Battery Installation
To install batteries in the Self-Leveling Cross and
Line Laser:
1. Remove the battery cover, which is located at the
back of the tool, by pressing the battery cover
release tabs found on the left and right side of
the tool and pulling the cover back.
2. nsert 2 “AA” batteries into the battery compart-
ment according to the polarity illustrated inside.
3. Replace the battery cover. Press in the release
tabs as you insert them into the tool housing.
Notes:
• Always check that the locking compensator/power switch is in the
locked position before removing and replacing batteries.
• Use only alkaline batteries.
• Remove the batteries when storing the instrument for an extended
time (more than 3 months) to avoid damage to the tool should the
batteries deteriorate.

Using the roduct in Self-Leveling Mode
1. Slide the locking compensator up to the unlocked position to
power on the unit. The status light will illuminate, and the unit will
emit both a crossline and a 90° vertical (plumb) line.
2. Press the tilt mode button once to produce only the crossline.
3. Press the tilt mode button a second time to produce only the 90°
vertical (plumb) line.
4. Press the tilt mode button a third time to again produce both a
crossline and a 90° vertical (plumb) line.
5. Slide the locking compensator down to the locked position to
power off the unit.
Note: The Self-Leveling Cross and Line Laser must be within ±4°
of level for the self-leveling feature to function properly. f the
instrument is beyond its 4° self-leveling range, the laser will not
self-level, the laser will flash and the status light will turn red. Once
the instrument has been adjusted to within its 4° self-leveling range,
the laser will self-level, the status light will turn green and the laser
light will stop flashing and remain solid.
Using the roduct in Tilt (Manual Level) Mode
The Crossline with 90º Plumb Line Laser can be used to project laser
beams at any angle desired, such as when projecting a line for stairs
or a railing. This mode produces the best results when the tool is
mounted on a tripod.
1. With the locking compensator down in the locked position, tap
the tilt mode button to power on the unit. The status light will
2891i-1English_Manuals 6/4/18 10:24 AM Page 9
10 ©2018 Johnson Level & Tool - Rev. 1
illuminate in red, and the unit will emit both a crossline and a
90° vertical (plumb) line.
Note: Relative orthogonal alignment of each of the beams will not
change from self-leveling mode, but the entire laser assembly will
not self-level.
2. Press the tilt mode button a second time to produce only the
crossline.
3. Press the tilt mode button a third time to produce only the vertical
(plumb) line.
4. Press the tilt mode button a fourth time to power off the unit.
Tips from the ros
• ncreasing the Beams’ Visibility – When working in bright
conditions, such as when working near windows or outside walls,
the visibility of the laser beams can be maximized by following
these steps:
• Work towards the laser.
• Use a freestanding target (sold separately).
• Wear laser glasses (sold separately).
Note: Laser glasses enhance beam visibility but should never be
used to stare into the beam or be used as safety glasses. Eye
damage may result if these directions are not followed.
