7.9.3.2 Cleaning the main cartridge
Only blow out the main cartridge -
never wash it or brush it out. When
blowing out, take care to ensure
that dust does not land on the in-
side of the main cartridge.
The main cartridge can be cleaned up to 5
times if necessary. The main cartridge must
be replaced once it reaches its maximum ser-
vice life of one year, at the latest. A record
must be kept of the number of times it is
cleaned.
For cleaning, a pipe with the end bent at 90°
should be attached to the compressed-air
pistol. The pipe must be long enough to reach
the floor of the cartridge. Blow out the main
cartridge from the inside to the outside with
dry compressed air (max. 5 bar) by moving
the pipe up and down in the cartridge. Contin-
ue until no more dust escapes (200).
Check the clean main cartridge for damage to
the paper bellows and rubber seals. Tears
and perforations in the paper bellows can be
determined using a torch.
Do not install damaged main car-
tridges. The diesel engine can be
damaged if dust is able to get into
it.
