6.3.1 Dirt filter
When using a dirt filter, the cooling air throughput is reduced and the duty cycle of the machine is reduced
as a result. The duty cycle decreases with the increasing contamination of the filter. The dirt filter must be
remove at regular intervals and cleaned by blowing out with compressed air (depending on the level of
soiling).
Figure 6-1
• Two dirt filters (option for retrofitting) can be installed on the machine. One at the air inlet of the power
unit (inverter) and one at the air inlet of the heat exchanger (torch cooling).
• Loosen the locking screws of the filters (pull the filter of the power unit downwards and then back-
wards and the filter of the heat exchanger downwards and then to the side).
Figure 6-2
• Blow out the dirt filter with compressed air free of oil and water.
Follow official regulations on disposal!
• After cleaning, refit the filters in reverse order.
