TROUBLESHOOTING CHART

POSSIBLE CAUSE
Close tank drain valve.
Check fittings with soapy water. Tighten or reseal leaking
fittings. DO NOT OVERTIGHTEN.
Clean or replace air filter element.
Decrease amount of air used.
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.
Check and replace if necessary.
WARNING：
Immediately replace tank. DO NOT attempt to repair.
Replace compressor assembly.
Replace compressor assembly.
Replace compressor assembly.
Replace regulator or internal parts.
If pressure drops to low, adjust regulator while accessory is used.
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.
Replace pressure switch
Replace pressure switch
Motor will start automatically when tank pressure drops
below kick-in pressure of pressure tank.
Let motor cool off and overload switch will automatically
reset. This may take several minutes.
Replace blown fuse or reset circuit breaker. Do not use
fuse or circuit breaker with higher rating than specified for
you branch circuit.
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.
Bleed line by moving pressure switch lever to OFF position
before restarting. If bleeder valve does not open, replace
bleeder valve.
Check for proper gauge and extension cord length.
