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.
