Maintenance
Calibration
There is no set interval for checking the calibration of the
L3
, 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 by
common carrier.
Batteries
From time to time, remove the batteries and check the contacts for
corrosion. Alkaline batteries will last far longer than carbon batteries. If
you use NiMh rechargeable batteries, be careful to never charge alkaline
or carbon batteries. Never run the laser from the charger unless there are
rechargeable batteries installed. Keep a spare set of alkaline 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.
Tripod mounting thread
Occasionally, the threaded hole for the tripod bolt should be lubricated
with a light oil.
Caution
Never store a laser in a wet carrying case. Moisture can get inside the
laser this way. The laser can get wet from rain during normal operation
and this is not a problem. However, once you are home or back at your
shop, be sure to leave the laser out of the case long enough for both the
laser and the case to dry off.
If the laser gets stored in the case wet for an extended period, and some
water gets inside, remove the battery cover and place the laser and the
open case in a warm, dry area until it is completely dry (free of
condensation inside the windows).
