Troubleshooting

Problem
Air Compressor will not start
Overheating
When in Auto/On position, motor
runs continuously
Air leak after motor stops at switch
release valve
Air leak while motor is running at
switch release valve
Air leak from safety relief valve
Air leaks at pump
Air leaks in tank
Air leaks at fittings
Air blowing from intake filter
Insufficient pressure for air tool or
accessory
Air compressor not making enough air
Rev 30000-20080208
Cause
Power cord
Motor Switch is in OFF position
Blown fuse, circuit breaker trip
Wrong gauge extension cord
Tank pressure is greater than auto
motor "kick in"
Defective motor, motor switch
Insufficient Ventilation
Dirty or obstructed cooling fins
Motor switch malfunction- does not
respond when tank reaches max
pressure, safety relief valve engage
Incorrect compressor size for tool
application
The check valve is stuck open
Defective motor switch
The check valve is stuck open
Malfunctioning safety relief valve
Excessive Tank Pressure
Malfunctioning/blown gaskets
Rusted, broken welds – Defective tank
Fittings are not sufficiently tight
Damage intake valve
Air leaks
Air compressor is not large enough for
particular air equipment
Pressure regulator is not set to
accurate pressure
Restricted air intake
Defective motor/pressure switch
Hose or hose connection(s) are
inaccurate size
Low compression
Malfunctioning intake filter
Leaking inlet valve
Troubleshooting
Solution
Plug into grounded outlet
Move lever to auto/on position
Replace fuse, reset circuit breaker
Unplug other appliances from same
outlet
Check gauge on cord and verify that it
is the correct size
Open tank drain valve to release tank
pressure
Call Champion Hotline #
Place compressor in environment with
well circulated supply of cool, dry air.
Clean surfaces of cooling fins on and
around pump/motor area
Move motor switch to OFF position.
If motor does not shut-off, unplug the
compressor. Evaluate motor switch
wiring. Replace if needed
The Air tool might be too big for the
compressor you are using. Use a
smaller air tool, or a larger
compressor
Remove, clean or replace check valve
Replace
Replace- NOTE – do not remove
while tank is pressurized. Release
tank pressure by opening tank drain
valve
Pull manually on ring. If valve does
not make a clean seal when closed,
replace.
Defective motor switch. Replace
Replace poor gaskets
Replace – Note – Do not attempt to
repair air tank!
Tighten fittings – Note- Do not over
tighten
Contact Champion Hotline #
Check for leaks on all fittings and
connections. Tighten or repair
connections as needed
Note the equipment requirement – if
higher then pressure supply of
compressor, or causes the motor to
run continuously, you need a larger
air compressor
Adjust pressure regulator knob to
correct setting
Clean or replace filter element
Replace
Assess and replace if necessary
Possible worn piston rings and/or
cylinder walls. Inspect and replace as
needed
Clean or replace filter element
Release all tank pressure, then
measure pump up time. Compare to
