Replacing alkaline batteries
Follow the steps below to replace the alkaline batteries in your laser.
• To access the battery compartment, loosen the knobs connecting the
laser to the wall mount.
• Use a coin or small screwdriver to remove the cover of the battery
compartment at the back of the laser.
• Insert two fresh alkaline batteries (D size or LR20), following the
polarization indicated at the bottom of the battery compartment. The plus
contact is rounded and raised. When replacing batteries, change both at
the same time.
• Replace the compartment and tighten with a coin or screwdriver.
Check and Adjust
Notes and Responsibilities
• It is the responsibility of the user to follow operating instructions and
to periodically check the accuracy of the instrument and work as it
progresses.
• The laser is adjusted to the defined accuracy specifications at the
factory. It is recommended to check your laser for accuracy upon receipt
and periodically thereafter to ensure accuracy is maintained. If your laser
requires adjustment, contact the nearest authorized service center.
• Accuracy adjustment should only be performed by a qualified
individual that understands basic adjustment principles.
Checking level accuracy
To check the level accuracy of your laser, place the unit on a flat, level
surface or tripod approximately 30 meters (100 ft.) from a wall.
• Align the X-axis so that it is square to the wall. Allow the laser to self-
level completely (approximately one minute after the laser begins to
rotate). Then mark the position of the beam (Position 1).
