Maintenance
Calibration
There is no set interval for checking the calibration of the L5, 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 Ni-Cd 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 (Ni-
Cd) 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.
Tripod mounting thread
Occasionally, the threaded hole for the tripod bolt should be lubricated
with a light oil.
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 and the open case in a warm area until it is
completely dry (free of condensation inside windows).

Accessories - Receivers
When your work takes you outdoors, a receiver is essential. No true
rotating laser can be used outdoors without a receiver as it would not be
safe or legal to put out enough laser power to make the rotating beam
visible in sunlight. There are two receiver choices available, the basic
R6 receiver and the more capable R7.
For most needs, the R6 is the recommended choice. It provid es
excellent functionality at a great price.
