Exhaust Plenum Cleaning
•
Power system ON.
•
Using the Z-axis controls, raise the Z-axis table as high as
possible. Power the system OFF.
•
Locate and remove the two button head screws (1) found
on the back of the laser system.
•
Open the front door. Using both hands, reach in and grab
exhaust plenum. Lift the plenum straight up until the tabs
(2) of the plenum clear the two flat head screws (3) they
are resting on. Tilt the bottom of the plenum towards you
and remove it from the system. Using your soap and water
solution, clean the inside of plenum as well as the inside
rear wall of the Laser System.
•
Installation is opposite of removal. Make sure that the
plenum tabs rest on the two flat head 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 of the laser system. To service the filters, first turn OFF
and unplug the laser system. There are two large filters (1) and two small filters (2). 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.
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.
