Solution
Compressor will turn on when tank
pressure drops to cut-in pressure.
Check to be sure unit is plugged in.
Replace shop/house fuse.
Reset shop/home breaker, determine why
problem happened.
First unplugged the compressor and
wait until it becomes cool. After that
compressor can be used.
Check for proper use of extension cord.
Replace pressure switch.
Check with voltmeter.
Check for proper gauge wire and cord
length.
Take compressor to service center.
Take compressor to service center.
Check for proper fuse, use time-
delay fuse, disconnect other electrical
appliances from circuit or operate
compressor on its own branch circuit.
Check for proper gauge wire and cord
length.
Take compressor to service center.
Check with voltmeter.
Move compressor to well-ventilated area.
Check for proper gauge wire and cord
length.
Check all connections with soap and
water solution and tighten.
Tighten drain valve.
Take compressor to service center.
WARNING:
Do not disassemble check valve with air
in tank - bleed tank.
Drain tank.
Move to area of less humidity; use air line
filter.
Ensure connections are sealed with
thread sealing tape and tightened.
Replace air hose.
Ensure tank drain valve is closed.
Take compressor to service center.
Decrease air usage; compressor not large
enough for tool's requirement.
Tighten mounting bolts.
Take compressor to service center.
Apply thread sealing tape to fitting and
tighten.
