TROUBLESHOOTING GUIDE (Continued)
CAUSE
Possible defect in safety valve.
PROBLEM
Air leak from safety valve.
Knocking Noise
Compressor is not supplying
enough air to operate accesso-
ries.
Motor will not run or restart.
Defective check valve.
Prolonged excessive use of air.
Compressor is not large enough for air
requirement.
Restricted air intake filter.
Hole in hose.
Check valve restricted.
Air leaks.
Motor overload protection switch has
tripped.
Tank pressure exceeds pressure
switch "cut-in" pressure.
Wrong gauge wire or length of exten-
sion cord.
Check valve stuck open.
Loose electrical connections.
Possible defective motor or capacitor.
Paint spray on internal motor parts.
Fuse blown, circuit breaker tripped.
Pressure releasevalve onpressure switch
has not unloaded head pressure.
CORRECTION
Operate safety valve manually by pulling on ring. If
valve still leaks, it should be replaced.
Remove and clean, or replace.
Decrease amount of air usage.
Check the accessory air requirement. If it is higher
than the SCFM or pressure supplied by your air
compressor, you need a larger compressor.
Clean or replace air intake filter. Do not operate the
air compressor in the paint spray area.
Check and replace if required.
Remove and clean, or replace.
Tighten fittings. (See Air Leaks Section of Trou-
bleshooting Guide.)
Let motor cool off and overload switch will automati-
cally reset.
Motor will start automatically when tank pressure
drops below "cut-in" pressure of pressure switch.
Check for proper gauge wire and cord length.
Remove and clean, or replace.
Check wiring connection inside pressure switch and
terminal box area.
Return to Sears Service Center for inspection or
replacement, if necessary.
Have checked at Sears Service Center. Do not
operate the compressor in the paint spray area. See
flammable vapor warning.
1. Check fuse box for blown fuse and replace, 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 time delay fuses are
acceptable.
3. Check for Iowvoltage conditions and/or proper exten-
sion cord.
4. Disconnect the other electrical appliances from
circuit or operate the compressor in its own
branch circuit.
