The Laser Does Not Turn On
• If AA batteries are being used, 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 or Li-ion rechargeable pack
are in proper working condition. If in doubt, try installing new
batteries.
• Be sure to keep the laser dry.
• If the laser unit is heated above 50 ˚C (120 ˚F), 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
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, 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, so that the laser is stable.
