5.4.2. Dry-type air cleaner maintenance
It is best to clean the filter cartridge only when
the maintenance indicator displays the appropri-
ate signal. This is only the case if the mainte-
nance indicator functions properly (chap. 6.1.).
Apart from this, the cartridge should be renewed
after 500 hours of operation.

Cleaning the filter cartridge
Dry contamination

– Using a compressed-air pistol with a bent tube
insert, blow through the cartridge from the in-
side with dry compressed air, moving up and
down, until no more dust is emitted.
Important !
The pressure must not exceed max. 5 bar.
Persons handling compressed air must
wear protective goggles. Never direct
the jet to animals, persons or yourself !
Wet or oily contamination
Replace the filter cartridge.
– Assembly is carried out in reverse order.
Check the seal insert of collar nut „5“, replace
the collar nut if the seal insert is missing. Ensure
that the dust extractor valve is correctly posi-
tioned downwards (fig. 31).
– When the filter has been installed, unlock
maintenance indicator „3“ – if installed – by
pressing reset button „4“ (fig. 33).
