PROBLEM
Pressure
reading on
the
regulated
pressure
gauge
drops when
accessory
is used.
Air leak
from safety
valve.
Compressor
is not
supplying
enough air
to operate
accessories.
Motor will
not run.
CAUSE
It is normal for
"some"
pressure drop
to occur.
Possible
defective
safety valve.
• Prolonged
excessive
use of air.
• Compressor
is not large
enough for
air
requirement.
• Restricted
air intake
filter.
• Unit is not
plugged in.
• Hole in hose.
• Check valve
restricted.
• Air leaks.
• Motor
overload
protection
switch has
tripped.
• Tank
pressure
exceeds
pressure
switch "cut-
in" pressure.
CORRECTION
If there is an excessive amount of
pressure drop when the accessory is
used, adjust the regulator following the
instructions.
Note:Adjust the regulated pressure
under flow conditions (while accessory is
being used).
Operate safety valve manually by pulling
on ring. If valve still leaks, it should be
replaced.
• 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.
• Plug unit into "live" electrical outlet.
• Check and replace if required.
• Remove and clean, or replace.
• Tighten fittings. (See Air Leaks section
of troubleshooting guide).
• Let motor cool off and reset overload
switch.
• Motor will start automatically when
tank pressure drops below "cut-in"
pressure of pressure switch.
