The motor will
not run or start.
The power cord is not plugged in. Plug the power cord into a grounded outlet.
The ON/OFF switch is in the
OFF (O) position. Set the ON/OFF switch to the ON (I) position.
The extension cord is the wrong
wire gauge or is too long. 7 for the proper wire gauge and cord length.
The motor’s thermal overload
protection has tripped.
Turn the air compressor off, unplug the
Check extension cord information page
power cord and wait until the motor has
cooled down. Plug in the power cord only
after the motor has cooled down, and wait
at least 15 minutes to make sure the
thermal overload protector has recovered.
A fuse has blown or a circuit
breaker has been tripped.
Replace the fuse or reset the circuit breaker.
Verify that the fuse has the proper amperage.
Check for low voltage conditions. Disconnect
any other electrical appliances from the
circuit or operate the compressor on a
dedicated circuit.
The air tank pressure exceeds
the preset pressure switch limit.
The motor will start automatically when the
tank pressure drops below the cut-in
pressure.
The safety valve is stuck open. Clean or replace the safety valve.
Electrical connections are loose.
Have the compressor serviced by a qualified
technician.
The motor, capacitor or safety
valve is defective.
Have the compressor serviced by a qualified
technician.
The pressure switch does not
shut off the motor when the air
compressor reaches the cut-out
pressure and the safety valve
activates.
Set the ON/OFF switch to the OFF position.
If the motor does not shut off, unplug the air
compressor. If the pressure switch is
defective, replace it.
The compressor’s capacity
is not enough.
Check air requirements of the accessory
that is being used. If it is higher than the
CFM (Cubic Feet per Minute, page 4)
and pressure supplied by the compressor, a
larger capacity air compressor is needed.
Most accessories are rated at 25% of actual
CFM while running continuously.
PROBLEM POSSIBLE CAUSES SOLUTIONS
The motor runs
continuously
when the
pressure switch
is in the ON
position.
PROBLEM POSSIBLE CAUSES
SOLUTIONS
The regulator
does not
regulate the
pressure.
The regulator or its internal parts
are dirty or damaged. Replace the regulator.
The pressure is
low or there is
not enough air.
There is a leak at one of the
fittings.
Check the fittings with soapy water. Tighten
or reseal leaking fittings (apply plumber's tape
on threads). Do not overtighten.
The tank drain valve is open. Close the drain valve.
Prolonged excessive use of air.
The air intake is restricted.
Decrease the amount of air used.
There is a hole in the air hose.
Replace the tank immediately. Do not attempt
to repair it.
Check for worn parts and replace them if
necessary.
CAUTION: Always replace a damaged gauge
before operating the unit again.
The tank leaks.
The check valve/pressure relief
valve/pressure regulating valve
is leaking.
Check the air hose and replace it if necessary.
There is
moisture in the
discharge air.
There is condensation in the air
tank caused by a high level of
atmospheric humidity or because
the air compressor has not been
running long enough.
Drain the air tank after each use. Drain the air
tank more often in humid weather and use an
air line filter.
The
compressor
overheats.
The ventilation is inadequate. Relocate the compressor to an area with cool,
dry and well-circulated air.
Cooling surfaces are dirty. Clean all cooling surfaces on the pump and the
motor thoroughly.
The check valve is leaking. Replace worn parts and reassemble using new
plumber's tape.
