EXTENSION
CORD WITH THIS
PRODUCT!
1.Incorrect size fuse circuit
overloaded
2.Defective check valve or
pressure switch
1.Check for proper fuse. Use timedelay
fuse. Disconnect from other electrical
appliances from circuit or operate
compressor on its own branch circuit
2.Contact Authorized Service Center
Thermal overload protector
Cuts out repeatedly
1.Low voltage
2.Clogged air filter
3.Lack of proper
ventilation/room temperature
too high
1.Check with voltmeter(105v.min)
2.Clean filter(see Maintenance section).
3.Move compressor to well ventilated area.
Tank pressure drops when
compressor shuts off
1.Loose connections(fittings
tubing. etc)
2.Open draincock.
