Compressor is not supplying
enough air to operate acces-
sories.
Prolonged excessive use of air.
Decrease amount of air usage.
Hole in hose.
Check and replace.
Check the accessory air requirement. If it is higher
than the SCFM or pressure supplied by your air
compressor, you need a larger compressor.
Compressor is not large enough for air
requirement.
Defective air tank.
CORRECTION
Excessive tank pressure -
safety valve pops off.
Pressure switch does not shut off
motor when compressor reaches “cut-
out” pressure.
Move the pressure switch lever to the “OFF” posi-
tion. If the outfit doesn’t shut off, unplug. If the
electrical contacts are welded together, replace
the pressure switch.
Pressure '"cut-out" too high.
Return the outfit to an authorized dealer to check
and adjust, or replace switch.

TROUBLESHOOTING GUIDE
PERFORMING REPAIRS MAY EXPOSE VOLTAGE SOURCES, MOVING PARTS OR COM-
PRESSED AIR SOURCES. PERSONAL INJURY MAY OCCUR. PRIOR TO ATTEMPTING ANY
REPAIRS, UNPLUG THE COMPRESSOR AND BLEED OFF TANK AIR PRESSURE.
CAUSE
Pressure reading on the regu-
lated pressure gauge drops
when an accessory is used.
It is normal for “some” pressure drop to
occur.
If there is an excessive amount of pressure drop
when the accessory is used, adjust the regulator
following the instructions on page 7.
NOTE
Adjust the regulated pressure under flow
conditions (while accessory is being used).
Air tank must be replaced. Do not repair the leak.
Possible defect in safety valve.
Operate safety valve manually by pulling on ring. If
valve still leaks, it should be replaced.
Air leak from safety valve.
Knocking Noise
Defective check valve.
