Note: Troubleshooting problems may have similar causes and solutions.
Close drain valve Tank drain valve is open
Check fittings with soapy water. Tighten or reseal leaking fittings.
DO NOT OVERTIGHTEN. Fittings Leak
Make sure air inlet vents are not covered or restricted. Restricted air intake
Decrease amount of air used. Prolonged excessive use of air
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously. Compressor not large enough
Check and replace if necessary. Hole in air hose
Immediately replace tank. DO NOT attempt to
repair. Tank leaks
Replace compressor assembly. Valve leaks
Replace compressor assembly. Leaking or worn piston
Replace compressor assembly. Blown seals
If pressure drops too low, adjust regulator while accessory is used. This is normal
Check air requirement of accessory. If it is higher than CFM and
pressure supplied by compressor, you need a larger compressor.
Most accessories are rated at 25% of actual CFM while running
continuously. Compressor not large enough
SOLUTION POSSIBLE CAUSE
Low pressure or not
enough air
or
Compressor does not
stop
Regulated pressure
gauge reading drops
when air accessory is
being used
PROBLEM
WARNING :
Replace pressure switch Tank pressure exceeded normal
operating pressure
Replace pressure switch Pressure switch stuck
Motor will start automatically when tank pressure drops below
kick-in pressure of pressure tank. Tank pressure exceeds preset
pressure switch limit
To reset the motor overload, toggle the ON/OFF switch to the
“OFF’ position and unplug the unit from the power outlet. Allow a
minimum of 10 minutes for motor overload cut-out to cool and
reset. Unit can then be plugged in and restarted. Motor overload protection has
tripped
• Reset circuit breaker. Do not use circuit breaker with higher rating
than specified for your branch circuit. Circuit breaker tripped
• Check for low voltage and proper extension cord size.
• Disconnect other applications from circuit. Operate compressor
on a dedicated circuit.
Remove and clean or replace. Check valve stuck open
Check for proper gauge and extension cord length. Wrong wire gauge in cord or
excessive extension cord length
Contact authorized service center. Loose electrical connections
Have checked at service center. Do not operate compressor in the
paint spray area Paint spray on internal motor
parts
Have checked at service center. Possible defective motor
Pressure relief valve
opens
Motor will not run
TROUBLESHOOTING CHART
Allow compressor to cool for approximately 30 minutes so thermal
overload switch will reset. Make sure compressor is run in a clean,
well-ventilated area where temperature will not exceed 100°F. Motor overheated
