Manifold Regulator Internally Damaged
Models: 4610, 4620, 5020W, 10020C, 10020CAD, 20020, 20020AD, etc.
Symptoms:
1. Tank Pressure Gauge reads normal and correct (i.e. 120 PSI) which signifies the motor-pump, pressure switch, check valve and
unloader valve are functioning correctly.
2. Regulator Pressure Gauge reads zero (0 PSI), or excessively low (i.e. less than 20 PSI), and no air output is available for
tooling.
Resolve Issue:
1. Turn off and unplug the air compressor.
2. Drain the air tank from the drain valve.
3. Replace the regulator assembly:

NOTE: in some cases cleaning the regulator may correct the issue if pressure is partially available (i.e. 20 PSI range or
similar).
4. Remove the regulator body from the manifold with a wrench.
5. Replace the regulator body, air piston, spring, cap and knob.
CAUTION: Replacing the original Industrial Female fitting on a new unit will void your warranty if damage is
incurred. The Industrial female fitting (or fittings) is attached with high-grade locktite to the manifold and should only be removed using a heat gun in
order to loosen the locktite. The manifold assembly may crack and leak air if improperly modified. For servicing personnel only!
