sion cord
Shorted or open motor winding
Defective check valve or unloader
Incorrect size fuse, circuit overload
Wrong gauge wire or length of exten-
sion cord

cord length
Take compressor to service center
Take compressor to service center
Check for proper fuse, use time-
delay fuse, disconnect other electri-
cal 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
DANGER:
Do not disassemble check valve
with air in tank — bleed tank.
Drain tank
Move to area of less humidity; use air
line filter
Take compressor to service center
Decrease air usage; compressor not
large enough for tool's requirement
Tighten mounting bolts
Take compressor to service center
Tighten connections
