Operate safety valve manually by pulling on ring. If valve

It is normal for some pressure drop to occur when an acces-
sory is used, adjust the regulator as instructed in Regulator
under Features if pressure drop is excessive.
NOTE: Adjust the regulated pressure under flow conditions
while accessory is being used.
Decrease amount of air usage.
Check the accessory air requirement. If it is higher than
the CFM or pressure supplied by your air compressor, a
larger compressor is needed to operate accessory.
Replace air hose.
Remove, clean or replace.
Tighten fittings.
Replace.
