Remove extension cord or use larger gauge
extension cord
Turn on pressure switch? Plugged in? Check fuse/
breaker or motor overload
Replace blown fuse
Reset, determining why problem happened
Unplug and allow motor to cool before trying to
restart
Replace
Replace motor
Check with voltmeter
Remove extension cord or use larger gauge
extension cord
Replace motor
Replace or repair
Check for proper fuse, use time-delay fuse.
Disconnect other electrical appliances from circuit or
operate compressor on its own branch circuit
Remove extension cord or use larger gauge
extension cord
Replace or repair
Check with voltmeter
Clean filter (see Maintenance section)
Move compressor to well ventilated area
Remove extension cord or use larger gauge
extension cord
Check all connections with soap and water solution
and tighten
Tighten
Disassemble check valve assembly, clean or replace
A.DANGER
Do not disassemble check valve
with air in tank;
bleed
tank first.
4 . Replace tank., Never repair a damaged tank.
1. Drain tank
2. Move to area of less humidity; use air line filter
1.
Replace switch
2. Decrease air usage; compressor not large enough for
a requirement
3. Air leaks 3. Check all connections with soap and water
Compressor vibrates Loose mounting bolts Tighten
---------~------------------
Air output lower than normal 1. Broken inlet valves 1. Have authorized service representative repair unit
2. Intake filter dirty 2. Clean or replace intake filter
3. Connections leaking 3. Tighten connections
