Troubleshooting
The motor is not
working.
The motor buzzes but
is not working or
works slowly.
Fuses blow.
The circuit switch
shoots repeatedly.
The thermal overload
protection causes
interruptions
repeatedly.
Tank pressure drops
when the motor stops.
Excessive humidity it
the discharge air.
The motor operates
continuously without
stopping.
The compressor
vibrates.
Air outlet is lower than
normal.
• There is no power.
• Blown fuse.
• Thermal switch activated.
• Pressure switch is failing.
• Voltage drops.
• Motor wiring in short or open.
• Faulty check valve or pressure
switch.
• Compressed air in the cylinder.
• Wrong capacity in the fuse,
overloaded circuit.
• Faulty check valve or pressure
switch.
• Voltage drops.
• Clogged air filter.
• Lack of adequate ventilation.
• Environment temperature is too
high.
• Loose connections (couplings,
pipes, etc.).
• Drain valve is open.
• Leaks in the check valve.
• Water in excess in the tank.
• High humidity.
• Admission filter is clogged.
• The pressure switch is failing.
• Excessive air use.
• Loose mounting knobs.
• The tank rubber base is not
installed or is worn.
• The drain valve is open.
• The admission filter is dirty.
• Leaks in one connection.
• Make sure the power cable is connected. Check the fuse – circuit
breaker.
• Replace the blown fuse.
• Turn OFF the compressor and wait a couple of seconds to let the
thermal switch to recover. Later turn ON the compressor.
• Go to a Authorized Service Center.
• Check the voltmeter. Minimum voltage shall be 115 V
• Go to a Authorized Service Center.
• Go to a Authorized Service Center.
• Press the switch 15 seconds into the OFF position, Then, lift to
the ON position.
• Check the right fuse is being used. Use a fuse with time delay.
Disconnect other appliances in the same circuit. Operate the
compressor using an independent circuit.
• Go to a Authorized Service Center.
• Check the voltmeter. Minimum voltage shall be 115 V
• Clean the air filter.
• Move the compressor into an area with adequate ventilation.
• Move the compressor into an area with adequate ventilation.
• Check to detect air leaks. Use sealing tape in al the leaky
connections.
• Tighten the drain valve.
• Disassemble the check valve. Clean or replace it.
DO NOT DISASSEMBLE THE CHECK VALVE
WHEN THERE IS AIR IN THE VALVE. FIRST, PURGE THE TANK TO
RELEASE ALL THE PRESSURE.
• Drain the tank opening the drain valve.
• Move the compressor into an area with less humidity. Use a filter
in the air piping.
• Clean or replace the filter.
• Go to a Authorized Service Center to
replace the pressure switch.
• The compressor is not big enough to satisfy the CFM
requirements of the pneumatic tool you are using.
• Tighten all the knobs and screws.
• Install or replace the rubber base.
• Tighten the drain valve.
• Clean or replace the admission filter.
• Tighten the connections. Check to detect leaks. Replace damaged
or broken hoses.
