40-6674
Thank you for purchasing this Johnson
self-leveling 3x360° laser featuring GreenBrite®
technology. This laser includes three 360° planes of
laser light for total jobsite coverage.
This tool comes with a Li-Ion battery and charger, or
the option to use 4 AA Alkaline batteries.
To use the Li-Ion battery: Make sure the battery is
charged (see CHARGING THE LI-ION BATTERY). Lift
the latch on the battery door (1) and insert the battery
pack (2). Press the battery door closed until the latch
engages.
To use 4 x AA Alkaline batteries: Insert the batteries
into the battery holder according to the indicated
polarity, lift the latch on the battery door and insert
the battery holder into the laser. Press the battery
door closed until the latch engages.
To charge the Li-Ion battery, remove it from the
tool by lifting the battery door latch and sliding out
the battery (reverse the steps above in INSERTING
BATTERIES).
Plug the charger into the battery and into 120V power
until the light on the charger turns green (about
4-6 hours). While the battery is charging, the laser
can be operated using the included alkaline battery
compartment.
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.

Tool does not power on or remain on
• Check battery polarity.
• Replace batteries.
• Ensure battery door is tight.
• Turn pendulum lock o, then on.
• Ensure the tool is within its self-leveling
range.
Laser light is dim
• Ensure fresh batteries are being used or the
Li-Ion battery pack is fully charged.
• Ensure laser is within operating temperature
range.
• Ensure battery door is secure.
• Ensure laser is within self-leveling range.
Laser appears out of calibration
• Ensure pendulum is in the unlocked position.
• Has the laser been dropped or subjected to
impact? It may need calibration.
• Contact Johnson Level & Tool for calibration
service. The laser does not contain any user-
serviceable parts.
Note: Do not disassemble; removal of any labels
will void your warranty.
•Read all operating instructions prior to use.
•Power on the laser by unlocking the pendulum
lock. The horizontal beam will be enabled.
•Cycle through the desired beams by pressing
. To use a detector (not included), activate
pulse mode by pressing . The PULSE LED will
illuminate.
•To operate the laser in manual mode (non self-
leveling), keep the pendulum locked and press
to enter manual mode, then press as
described above to cycle through your desired
beams. The MANUAL LED will blink to indicate
manual mode is engaged.
• If the laser is in self-leveling mode and is not
able to self-level, both laser beams will flash and
the unit will beep to alert you that it is out of
level.
•If the battery is running low, the low battery
indicator LED will flash. A solid red battery
indicator indicates there is adequate battery life
remaining.
•Store the tool in its case with the pendulum
locked. For extended storage (>3 months),
remove the batteries to prevent corrosion.
•Set the laser on a tripod 10’ from all walls.
•Make a horizontal mark on the wall anywhere
along the 360° line to indicate the height of
the beam. Label this as Point A.
•Turn the laser 90° and mark Point B on the
same spot on the wall as Point A where the
beam intersects. This mark should either be
directly above, below or on top of Point A.
•Repeat Step 3 twice more, labeling the marks
as Point C and Point D, respectively.
•Measure the greatest vertical distance (H)
between any two of the points A, B, C & D.
•If ‘H’ < 1/16” for walls 10’ away from the tool,
the accuracy of the instrument is within its
specifications and no calibration is necessary. If
calibration is required, please contact Johnson
Level & Tool to obtain service at the address to
the bottom right.
•Place the laser on the floor 10’ from a doorway.
Project the plumb beam through the doorway.
•Mark the beam on the floor near the tool as
Point 1. Mark a spot 20’ away as Point 2.
•Mark the beam directly under the doorway as
Point C. Mark the beam on the doorway as D.
•Move the laser to Point 2, and aim the plumb
beam directly through Point 1 and Point C.
•Mark on the doorway Point E.
•Measure the distance
between Point D and
Point E.
•If this distance is less
than 1/16” for a 7’ high
doorway, then the tool
is properly calibrated.
•Complete the above
steps for each of the
two vertical beams.
