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
Clean or replace air filter element. 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
Replace regulator or internal parts. Dirty or damaged regulator
internal parts.
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
Air leaks from regulator,
or regulator does not
regulate pressure
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
Let motor cool off and overload switch will automatically reset. This
may take several minutes. Motor overload protection has
tripped
• Replace blown fuse or resed circuit breaker. Do not use fuse or
circuit breaker with higher rating than specified for your branch
circuit.
Fuse blown or circuit breaker
tripped
• Check for proper fuse; “Fusetron” type T is acceptable.
• 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
Bleed line by moving pressure switch lever to OFF Position before
restarting. If bleeder valve does not open, replace bleeder valve. Pressure bleeder valve on
pressure switch has not
unloaded head pressure
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
Contact authorized service center. Possible defective capacitor
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
