7.9.5.4 Cleaning the main cartridge
Never wash or brush out the main
cartridge.
Make sure that no dust ends up on the
inside of the main cartridge when blowing
out.
•
The main cartridge can be cleaned up to five
times if necessary. It must be replaced once it
reaches its maximum service life of two years,
at the latest. The number of times it is cleaned
must be marked.
•
For cleaning, a pipe the end of which is bent at
90° should be attached to the compressed-air
pistol. It must be sufficiently long 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 and continue until
no more dust escapes.
•
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.
Never continue to use damaged main
cartridges. If in doubt, use a new one.
