CHECKING FANS AND AIR VENTS
WARNING: Before undertaking any work on the laser marking system, unplug
the mains power.
The fans are located at the bottom of the control unit.
A fan defect immediately poses a danger of overheating that may result in damage to the
control unit, therefore the fans must be checked once a month.
