TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
Leakage of air from the valve of the
pressure switch with the compressor off.
Check valve that, due to wear or dirt on
the seal, does not perform its function
correctly.
Unscrew the hexagonal head of the
check valve, clean the valve seat
and the special rubber disk (replace
if worn). Reassemble and tighten
carefully (Figs. 14).
Reduction of performance. Frequent
start-up. Low pressure values.
Excessive performance request, check
for any leaks from the couplings and/or
pipes. Intake filter may be clogged.
Replace the seals of the fitting, clean
or replace the filter.
The compressor stops and restarts
automatically after a few minutes.
Tripping of the thermal cutout due to
overheating of the motor.
Clean the air ducts in the conveyor.
Ventilate the work area. Reset the
thermal cutout. On lubricated type
models, check oil level and quality.
After a few attempts to restart, the
compressor stops.
Tripping of the thermal cutout due to
overheating of the motor (removal of
the plug with the compressor running,
low power voltage).
Activate the on/off switch. Ventilate the
work area. Wait a few minutes. The
compressor will restart independently.
Remove any power cable extensions.
The compressor does not stop and the
safety valve is tripped.
Irregular functioning of the compressor
or breakage of the pressure switch.
Remove the plug and contact
the Service Center.
