Solution
• Make sure the power cable is connected. Check the fuse – circuit
breaker.
• Replace the blown fuse of instalation.
• Turn OFF the compressor and wait a couple of seconds to let the
thermal switch to recover. Later turn ON the compressor.

• 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.

• Disassemble the check valve. Clean or replace it.
DANGER
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
replace the pressure switch.
• The compressor is not big enough to satisfy the CFM
requirements of the pneumatic tool you are using.
• Make sure the drain valve is completely closed
• 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.
