PROBLEM

CAUSE

CORRECTION

Compressor is 
not supplying 
enough air 
to operate 
accessories.

Prolonged excessive use 
of air.
Compressor is not large 
enough for air requirement.

Hole in hose.

Check valve restricted.

Air leaks.

Restricted air intake filter

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.

Remove and clean, or replace.

Tighten fittings. 

Clean or replace air intake 
filter. Do not operate the 
air compressor with the 
filter removed. Refer to the 
"Air Filter" paragraph in the 
"Maintenance" section.

Pressure reading 
on the regulated 
pressure gauge 
(if equipped) 
drops when an 
accessory is 
used.

It is normal for "some" 
pressure drop to occur. 

If there is an excessive amount 
of pressure drop when the 
accessory is used, adjust the 
regulator as instructed in the 
Operation section.

NOTE: 

Adjust the regulated 

pressure under flow conditions 
(while accessory is being 
used).

Possible defect in safety 
valve.

Operate safety valve manually 
by pulling on ring.  If valve still 
leaks, it should be replaced.

Air leak from 
safety valve.

Clean or replace.  See "Air 
Filter" paragraph in the 
"Maintenance" section.

Dirty air filter.

Restricted air 
intake

Damaged regulator

Have checked by a Trained 
Service Technician.

Regulator knob 
has continuous 
air leak. 

Regulator will 
not shut off air 
outlet.

Damaged regulator

Have checked by a Trained 
Service Technician.
