screws.
Cooling Fan Filters
This air-cooled laser system will require periodic cleaning of
the cooling fan filters. Since ambient air is used to cool the
laser cartridge, the air must be filtered before it enters the
inside of the laser system. Dirt or dust contamination may
reduce the cooling fan's ability to keep the laser cartridge, as
well as the CPU and power supply, from overheating. An
overheated laser cartridge will lose laser power during
engraving and will eventually shut down completely.
The cooling fan filters are located on the back, and side of
the laser system. To service the filters, first turn OFF and
unplug the laser system. To remove the filter(s), simply snap off the black cover and remove the foam
element. Wash the element in a soap and water solution, dry, and re-install.
NEVER OPERATE THE LASER SYSTEM WITH THE COOLING FAN FILTERS
REMOVED. This can permanently damage the laser system. Damage to the laser
system, from this kind of abuse IS NOT covered under warranty.
Battery Replacement
There is a battery located on top of the CPU that is used to retain Z-axis position information when the
system is powered OFF. Normally, it is not necessary to replace this battery. However, if instructed
to do so by technical support, they will provide you with the correct battery replacement procedure.
WARNING: There is a danger of explosion if the battery is incorrectly replaced. Replace
the battery only with the same or equivalent type recommended by the battery
manufacturer. Using an incorrect battery, recharging or disassembling the battery may
present a danger due to fire or explosion. Dispose of used batteries promptly according
to local regulations.
BASIC MAINTENANCE
If your system is equipped with Air Assist, using your fingers, rotate
the beam window cover counter-clockwise (B) and then off at a 45-
degree angle. If the beam window cover is stuck use a 1/16 Allen
wrench to loosen or remove the screw (A) and try again. Set the
cover off to the side and clean the optic, if necessary. Reinstall the
beam window cover opposite of removal being careful not to
scratch the optic.
