otherwise modify air tank or it will weaken. The air tank can
rupture or explode.

Operate safety valve manually by pulling on ring. If valve still
leaks, it must be replaced.
It is normal for some pressure drop to occur when an accessory
is used, adjust the regulator as instructed in 'Adjusting Operating
Pressure' if pressure drop is excessive.

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.
