Do Not Overtighten.
Air tank must be replaced.
Do not repair the leak.
Risk bursting.
Do not drill into, weld or
otherwise modify air tank
or it will weaken. The tank
can rupture or explode.
Have checked by a Trained
Service Technician.
Operate safety valve manually
by pulling on ring. If valve still
leaks, it should be replaced.
If there is an excessive amount
of pressure drop when the
accessory is used, adjust
the regulator following the
instructions in the Description
of Operation paragraph in
the Operation Section.
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 SCFM or pressure supplied
by your air compressor, you
need a larger compressor.
Check and replace if required.
