the trap.
2. Remove the retaining nut (2) and withdraw the element (7) from
the housing (9).
If the element is to be serviced for immediate reuse, reinstall the

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.
COOLERS
Keep the coolers clean to maintain the cooling efficiency.
Service doors are provided in both sides of the fan cowl to allow
easy access to the fan side surface of the coolers. A service door in
the bottom of the fan cowl is provided to remove dirt. The door can
be opened from the inside of the fan cowl.
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 soak in period.
Steam-cleaning may also be applied.
Close the service doors. Do not leave liquids behind.
❖ Protect the electrical and regulating equipment, air filters, etc. against
penetration by moisture.

authorized representative of the valve supplier.
Following checks must be carried out:
Ð a check of the opening of the lifting gear, twice a year. This can
be done by screwing the cap of the valve anticlockwise.
Ð 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.
