MAINTENANCE AND FAULT FINDING

CHECKING FANS AND AIR VENTS
The fans are located at the sides of the control unit and on the laser head.
A fan defect immediately poses a danger of overheating that may result in
damage to the control unit and laser head, therefore the fans must be
checked once a month.
Control Unit and Laser Head Fans
(1) Check the fans for bearing noises. If bearing noises exist, the
respective fan must be replaced.
(2) Check the fan filters of the controller (2 on the left side and 2 on the
right side) for blockages and dirt. If necessary exchange them. This
may be easily done from the outside without opening the controller.
Laser Head Air Vents
(1) The air vents must be regularly checked for dirt and cleaned when
necessary.
CLEANING THE LENS
The lens must be checked monthly for dust, and if necessary be cleaned
with (absolutely clean) compressed air from a can.
For all other dirt, the lens must be cleaned with Isopropyl Alcohol and lens
paper, or cotton swabs (Q-tips), as follows:
(1) Take an unused cotton swab (Q-tip) and soak one end in Isopropyl
Alcohol.
(2) Lightly wipe with ONE PASS ONLY across the surface of the lens.
WARNING: Before undertaking any work on the
laser marking system, remove the
mains power plug.
CAUTION: Do not use a water hose to clean the air
vents.
WARNING: Ensure the mains power plug is
removed before cleaning the lens.
CAUTIONS: (1) Do not use compressed air from the
installation for cleaning.
(2) Water must not be used for cleaning, as the
lenses are not water resistant.
(3) Clean carefully as there is a risk of scratch
marks on the lens which will reduce the
marking quality.
