Constructed from solid brass with "0" ring seals, the L350-5 Mining
Alignment Laser is water tight to +1atmosphere. Integral mounting is
provided for use with spad or other style support. The Laser Beam is
concentric to the outside diameter of the battery compartment. This
product is tested for Intrinsic Safety and is MSHA approved for use in
Methane/Air mixtures only. When properly maintained, it is MSHA
approved for use with 1.5 volt "AA" Duracell MN1500 or Eveready E91
batteries. Replacement of the batteries must be performed in fresh air
ONLY. When replacing the batteries, the negative end goes into the
laser first. All positive ends must point towards the switch cap. All
batteries must be replaced at the same time. Never attempt to reuse
batteries. Do not mix batteries of different manufacturers or types.

OPERATION

The laser is shipped with an insulator to prevent the batteries from
powering the unit and discharging during shipment and storage. It must
be removed from the under the switch cap prior to use. To remove it,
unscrew the switch cap completely, remove the cardboard insulator and
replace the switch cap. Operation of the laser is simple and
straightforward. Two hanging brackets with adjustable tabs are integral
on the laser top and are used to suspend the laser from two spads or
some other means of sturdy roof support. Bailing wire, chain, rope or
other means of suspension can be used to hang the laser and provide a
means of adjusting for elevation. This laser has sufficient mass to help
prevent it from swaying in entries with high airflow. The end cap is turned
in the clockwise direction until the laser is powered. Do not over tighten.

Turn in the counterclockwise direction to turn the unit off. When the laser
fails to power up, the batteries will need to be replaced. To replace the
batteries, unscrew the switch cap completely, remove the old batteries
and inspect the interior of the battery compartment for signs of dirt,
moisture or leakage from the batteries. Correct any problems with acid
leakage or case sealing before installing new batteries. Replace the
batteries in fresh air ONLY. When replacing the batteries, the negative
end goes into the laser first. All positive ends must point towards the
switch cap. All batteries must be replaced at the same time. Do not
attempt to reuse batteries or mix batteries of different manufacturers or
types. Other than the batteries, there are no user serviceable parts on
the laser. This product is warranted for a period of one year from the date
of purchase for manufacturing defects. The manufacturer reserves the
right to repair or replace this product if it fails due to manufacturing
defects during the warranty period. Abuse, neglect or disassembly of
the laser voids this warranty. Like any other tool, the service that this
product will provide is dependent on the care it receives. Please return it
to your nearest Mine Supply Dealer for service and repair.
