Maintenance And Troubleshooting
Calibration • There is no set interval for calibrating the L1-AS, but calibration
should be checked from time to time in order to ensure that the highest possible
quality of work is being done. Calibration should always be checked if the laser
has been handled roughly or shipped.
Batteries • Occasionally remove the batteries and check the contacts for corrosion.
Alkaline batteries will last far longer than carbon batteries.
If you use
rechargeable batteries, be careful to never charge alkaline or carbon batteries.
Also, do not charge Ni-Cd batteries too often. Ni-Cd batteries should be charged
after about 20 to 24 hours of operation. Never run the laser from the charger
unless there are rechargeable batteries installed. Keep a spare set of batteries in
the carrying case to avoid down time.
Laser output windows • Regularly check the output windows for dust and dirt.
Dust can be removed with a camera brush or clean compressed air.
Control panel and exterior • Clean the control panel and the other exterior
surfaces of the laser with a soft damp cloth.
Caution • Never store the laser in a carrying case that is wet inside. Moisture can
get inside the laser this way. Should this happen, remove the battery cover and
place the laser in a warm area until it is completely dry.
Troubleshooting
The laser will not operate, there is no obvious damage • If the low battery indicator
is on, or you suspect the batteries may be dead, replace the batteries. Check the
battery contacts to be sure that they are clean.
The receiver shows an on-grade at two different heights • Check the jobsite for
windows or mirrored surfaces that might be reflecting the laser and causing the
other reading. Check for others on the site using a rotary laser.
The laser was knocked over • Visually check the optics for damage. Inspect the
laser for any other physical damage. Use the receiver to check that the laser is
transmitting. Check the calibration and adjust as needed.
The laser only works at short distances • Check the output windows for heavy dust
or moisture. Remove dust with a camera brush or blow off gently with clean
compressed air. Allow moisture to dry.
The receiver does not indicate "on grade" at long distance • Be sure you are within
the max distance specification from the laser. Check the windows that surround
the rotating mirror on the laser for dust or moisture. Remove dust with a camera
brush or blow off gently with clean compressed air. Allow moisture to dry.
