Troubleshooting
EN
The Laser Does Not Turn On
• Make sure AA batteries (when used) are installed correctly
according to (+) and (–) on the inside of the battery door.
• Make sure the batteries or rechargeable pack are in proper
working condition. If in doubt, try installing new batteries.
• Make sure that the battery contacts are clean and free of rust or
corrosion. Be sure to keep the laser level dry and use only new,
high-quality, name brand batteries to reduce the chance of battery
leakage.
• 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 pressing
the on/off button 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.
The Battery Meter LEDs Flash
When all 4 LEDs continuously flash on the Battery Meter this indicates
that the unit has not been fully powered off using the Pendulum Lock
switch . The Pendulum Lock switch should always be placed in the
B
LOCKED/OFF position when the laser is not in use.
