TROUBLESHOOTING
NOTE: Troubleshooting problems may have similar causes and solutions.
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Low pressure not
enough air or
compressor does not
stop
Tank d
r
ain valve is open Close tank drain valve.

reseal leaking fittings. DO NOT OVER
TIGHTEN.
Prolonged or excessive
use of air
Decrease amount of air used.
Compressor not large
enough
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.
Hole in air hose Check and replace if necessary.
Tank leaks
WARNING: Immediately replace tank.
DO NOT attempt to repair.

Motor will start automatically when tank
pressure drops below tank cut-in pressure.
Fuse blown or circuit
breaker tripped
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.
