Check valve that, due to wear or dirt on the seal,
does not perform its function correctly.
Excessive performance request, check for any
leaks from the couplings and/or pipes. Intake
filter may be clogged.
Tripping of the thermal cutout due to overheating
of the motor.
Tripping of the thermal cutout due to overheating
of the motor (removal of the plug with the
compressor running, low power voltage).
Irregular functioning of the compressor or
breakage of the pressure switch.
The compressor must be disposed in conformity with the methods
provided for by local regulations
CAUSE
Unscrew the hexagonal head of the check valve,
clean the valve seat and the special rubber
disk (replace if worn). Reassemble and tighten
carefully (figures 14a-14b).
Replace the seals of the fitting, clean or replace
the filter.
Clean the air ducts in the conveyor. Ventilate
the work area. Reset the thermal cutout. On
lubricated and V type models, check oil level
and quality. On V models, have the voltage
checked.
Activate the on/off switch. Ventilate the work
area. Wait a few minutes. The compressor will
restart independently. On V, 3 HP models, reset
the thermal cutout. Remove any power cable
extensions.
Remove the plug and contact the Service
Center.
