to make sure it is properly calibrated.

Troubleshooting
The Laser Does Not Turn On
• Check the AA batteries to make sure:
• Each battery is installed correctly, according to (+) and (–)
listed inside the battery compartment .
• The battery contacts are clean and free of rust or corrosion.
• The batteries are new, high-quality, name brand batteries
to reduce the chance of battery leakage.
• Make sure the AA batteries are in proper working condition. If
in doubt, try installing new batteries.
• When using rechargeable batteries, make sure the batteries
are fully charged.
• Be sure to keep the laser dry.
• If the laser unit is heated above 120 ˚F (50 ˚C), the unit will
not turn ON. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be
damaged by using the Power/Transport Lock switch before
cooling to its proper operating temperature.
The Laser Beams Flash
When in self-leveling mode, the lasers are designed to self-
level up to an average of 4° in all directions. If the laser is tilted
so much that the internal mechanism cannot level itself (or the
laser is not level when in manual mode ), the laser beams will
flash indicating that the tilt range has been exceeded.
THE FLASHING BEAMS CREATED BY THE LASER ARE
NOT LEVEL OR PLUMB AND SHOULD NOT BE USED
FOR DETERMINING OR MARKING LEVEL OR PLUMB. Try
repositioning the laser on a more level surface.
The Laser Beams Will Not Stop Moving
The laser is a precision instrument. Therefore, if it is not
positioned on a stable (and motionless) surface, the laser will
continue to try to find level. If the beam will not stop moving, try
placing the laser on a more stable surface. Also, try to make
sure that the surface is relatively flat and level, so that the laser
is stable.
Service and Repairs
Note: Disassembling the laser level will void all warranties on
the product.
To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by
authorized service centers. Service or maintenance performed
by unqualified personnel may result in a risk of injury. To locate
