Main part
Servicing
The instructions apply to one filter; they should be repeated for all other fil-
ters.
1. Release the snap clips (1) and remove the dust trap (3). Clean the trap.
2. Withdraw the element (7) from the housing (9).
If the element is to be serviced for immediate re-use, reinstall the
dust trap to protect the air intake system while cleaning the element.
3. Reassemble in reverse order of dismantling.
4. Inspect and tighten all air intake connections.
Cleaning
1. Release the four snap clips (1) that secure the dust trap to the filter
body and remove the dust trap.
2. Pry off the plastic baffle (4) from the dust trap and empty the latter.
3. Clean the dust trap and baffle and reassemble them, taking care that the
slot in the baffle fits over the stud of the trap.
4. Reinstall the dust trap on the filter body, with the side marked TOP
upwards, and secure it with the clips. Never use oil in the traps.
C
OOLERS
Keep the coolers clean to maintain the cooling efficiency.
Remove any dirt from the coolers with a fibre brush. Never use a wire brush
or metal objects. Then clean by air jet in reverse direction of normal flow.
If the dirt is oily, wash the coolers with fuel or a cleaning agent. A spray
gun should preferably be used to apply the solvent to the fins. Rinse the
block by means of a water jet after a soaking-in period. Steam-cleaning
may also be applied.
Do not leave liquids behind.

AFETY
VALVE
Following checks must be carried out:
– a check of the opening of the lifting gear, twice a year. This can be done
by screwing the cap of the valve anti-clockwise.
– a check of the set pressure once a year according to the local regulations.
This check cannot be done on the machine and must be carried out on a
proper test bench.
Never remove the elements while the compressor is
running.
The elements may not be washed more than three
times.
New elements must also be inspected for tears or
punctures before installation.
Discard the elements when damaged.
A dirty safety cartridge is an indication of a mal-
functioning air filter element. Replace the element
and the safety cartridge in this case.
Replace the safety cartridges together with the filter
elements. The safety cartridges cannot be cleaned.
