CHECK THE NON RETURN VALVES
If the tank pressure decreases for no apparent reason, it is possible that the
non-return valve is leaking. To check, ensure the tank is under pressure and the
machine switched OFF,
1. Take off the flexible hose and check if air leaks out from the valve.
2. If so, unscrew the valve from the
connection and disassemble it as
shown.
3. Clean all the components with a
dry cloth and reassemble the
valve taking care to place the
internal rubber disc(2) as shown.
4. Fasten the valve to the connection and join the flexible hose. If the
leakage persists, the whole valve must be replaced.
REPLACING THE AIR OUTLET FILTER
NOTE:
The compressor must be completey depressurised before carrying
out this procedure.
1. Unscrew the cartridge from the air
filter assembly.
2. Uncrew and replace the small air
filter.
