PROBLEM CAUSE CORRECTION
Motor overload protection switch has
tripped.
Possible defective starting capacitor.
Possible defective motor.
Tank pressure exceeds pressure switch
"cut-in" pressure.
Check valve stuck open - fails to relieve
head pressure; motor cannot start.
Loose electrical connections.
Fuse blown, circuit breaker tripped.
Pressure release valve on pressure switch
has not unloaded head pressure.
Paint spray on internal motor parts.
Dirty air filter.
Prolonged excessive use of air.
Compressor is not large enough for air
requirement.
Restricted air intake filter.
Loose belt.
Hole in hose.
Check valve restricted.
Air leaks.
Motor will not run.
Restricted air intake.
Compressor is not supplying enough air to
operate accessories.

check for defective capacitor.
Contact Authorized Warranty Service
Center for inspection or replacement if
necessary.
Have checked by a local Authorized War-
ranty Service Center.
Motor will start automatically when tank
pressure drops below "cut-in" pressure of
pressure switch.
Remove and clean, or replace. DO NOT
OVER-TIGHTEN. (See page 11)
Check wiring connection inside pressure
switch and motor terminal box area.
1.Check fuse box for blown fuse and re-
place if necessary. Reset circuit
breaker. Do not use a fuse or circuit
breaker with higher rating than that
specified for your particular branch
circuit.
2. Check for proper fuse; only Buss
"Fusetron" Type T fuses are accept-
able.
3. Check for low voltage conditions.
4. Remove check valve and clean or re-
place if it is stuck open or closed. (See
page 11)
5. Disconnect any other electrical appli-
ances from circuit. The compressor
must operate on its own branch circuit.
6. Do not use an extension cord.
Bleed the line by pushing the lever on the
pressure switch to the OFF position, open-
ing the pressure release valve. If the valve
still doesn't open, it must be replaced.
Have checked by an Authorized Warranty
Service Center. Do not operate the com-
pressor in the spray area. See Flammable
Vapor Warning.
Replace filter.
Decrease amount of air usage.
Check the accessory air requirement. If it
is higher than the CFM, SCFM or pressure
supplied by your air compressor, you need
a larger compressor.
Clean or replace air intake filter. Do not
operate the compressor in the paint spray
area.
Adjust belt tension. (See page 12)
Check and replace if required.
Remove and clean or replace. (See page
11)
Tighten fittings. (See "Air Leaks" section of
"Troubleshooting Guide".)
