TROUBLESHOOTING
Symptom 1: The motor will not run or restart
PROBABLE CAUSE
Power cord not plugged in.
Motor/Pressure switch is in “OFF” (0) position.
Motor thermal overload switch has tripped.
Fuse blown or circuit breaker has tripped.
Wrong gauge wire or length of extension cord.
Air tank pressure exceeds motor/pressure switch
“cut-in” pressure.
Pressure release valve on motor/pressure switch
has not unloaded pump head pressure.
REMEDY
Plug cord into grounded outlet.
Move switch to “ON” (1) position.
Turn air compressor o ff , wait until motor is cool,
then check motor circuit breaker.
Replace fuse or reset circuit breaker.
Check for proper fuse amperage.
Check for low voltage conditions.
Disconnect any other electrical appliances from
circuit or operate air compressor on its own branch
circuit.
Check chart on page #10 for proper gauge wire and
cord length.
Motor will start automatically when air tank pressure
drops below “cut-in” pressure of motor/pressure
switch.
Bleed the line by moving the switch to the “O ff ” (0)
position.

Symptom 2: When in start/stop postion, the motor runs continously
PROBABLE CAUSE
Motor/Pressure switch does not shut o ff the motor
when the air compressor reaches “cut-out”
pressure and safety relief valve activates.
The air compressor is incorrectly sized.
REMEDY
Move the motor/pressure switch to the “O ff ”(0)
position, If the motor does not shut o ff , unplug the
air compressor. If the electrical contacts are welded
together, replace the pressure switch.
Limit the air pressure to the capacity of the air
compressor. Either use a smaller tool or a larger air
compressor.
Symptom 3: Air continues to leak at motor/pressure switch release valve after motor stops.
PROBABLE CAUSE
The check valve is stuck open.
REMEDY
Remove, clean or replace.
Symptom 4: Air continues to leak at motor/pressure switch release valve while motor is running
PROBABLE CAUSE
Defective motor/pressure switch.
REMEDY
Replace
Symptom 5: Air blowing from inlet fi lter
PROBABLE CAUSE
Damaged inlet (reed) valve.
