TEST OR INSPECTION
NOZZLE PRESSURE BELOW 90 PSI (Continued)
If a back pressure can be felt at the air filters when the compressor is running, go to Step 7.
Remove the filter elements and inspect them.
If they are plugged with dirt, replace them and go to Step 3c.
If they are ok, go to Step 4.
After replacing the filter elements, start the engine and check the pressure again.
If the pressure is 90-100 psi, the problem is solved.
If the pressure is still less than 90 psi, go to Step 4.
Check the pipe fittings listed below for air leaks.
