SAFETY INSTRUCTIONS
WARNING
This product is emitting radiation that is classified
As class II according to EN 60825 -1
The laser radiation can cause serious eye injury
• Do not stare into the laser beam
• Do not position the laser beam so that it unintentionally
blinds you or others.
• Do not operate the laser level near children or let children
operate the laser level.
• Do not look into a laser beam using magnifying optical
devices such as binoculars or a telescope, as this will
increase the level of eye injury.
WARNING: This product contains lead in solder and
certain Electrical parts contain chemicals which are
known to the State of California to cause cancer, birth
defects or other Reproductive harm.
(California Health & Safety Code Section 25249.6- Proposition 65)
NOTE
The red goggles are intended to enhance the
visibility of the Laser beam. They will not
protect your eyes against laser radiation.

• Do not remove or deface warning labels on the laser level.
• Do not disassemble the laser level, laser radiation can
cause serious eye injury.
• Do not drop the laser.
• Do not use solvents to clean the laser.
• Do not use in temperatures below -10°C or above 45°C

cause ignition.
• When not in use, turn off the power, engage the pendulum
lock and place the laser in the carrying pouch.
• Make sure the pendulum lock mechanism is engaged
before transporting the laser.
NOTE
If the Pendulum lock mechanism is not
engaged before Transportation, internal
mechanical damage can occur.

1. Press on the latch and open the battery cover.
2. Insert 3 new AA batteries of the same brand, according
to the polarity diagram on the inside of the lid of the battery
compartment.
3. Reclose the battery cover.
BATTERY INSTALLATION & SAFETY
NOTE
If the laser level will not be used for a long
period, remove the batteries from the battery
compartment. This will prevent batteries from
leaking and corrosion damage.

OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself at a ± 3°
range and will project horizontal or vertical beams or both
beams simultaneously.

3.To mark a slope, tilt the laser to adjust the right angle and the
height.
4.To turn the manual mode off, press again the Manual mode button
5.While in Manual mode, turning the locking switch #1 from OFF
to ON will turn off the Manual mode and the red LED near the

Working in Pulse mode with a detector:
For outdoor work under direct sunlight, or bright conditions
and for extended indoor ranges up to 50 meters, use the
pulse mode with a Detector.

procedures.
• Change the batteries when the laser beams begin to dim.
• Wipe the aperture lens and the body of the laser level with a
clean soft cloth. Do not use solvents.
• Although the laser level is dust and dirt resistant to a certain
degree do not store in dusty places as a long term exposure
may damage internal moving parts.
• If the laser level is exposed to water, dry the laser level
before returning it to the carrying case to prevent corrosion
damages.
• Remove the batteries if the laser level is unused for a long
period of time to prevent corrosion damages.

FIELD CALIBRATION TEST
This laser level left the factory fully calibrated.
Kapro recommend that the user will check the accuracy of the
laser periodically, or if the unit falls or is mishandled.
