7. Clean and enlong the spring
8. Replace the spring and cap.

10. Plug in the power cord and turn on the air compressor.

Not Building Pressure

Motor/Pump Piston Ring or Reed Valves are Worn.

 

Over time piston rings and reed valves can wear because of usage.

Standard maintenance is required.

 

If air is pushing out from the air filter and not sucking into the air filter,

the Reed Valve is damage.

 

Resolve Issue:

Replace the piston rings and reed valves.

98% Air Dryer Low Air Output (DCADC & DSMADC 98% Dry Air models)
