TROUBLESHOOTING

PROBLEM

CAUSE

CORRECTION

Unit is Leaking 

Oil at Fitting(s)

Loose Fitting.

Tightening fitting resolves most issues.

Rust in Water 

When Draining 

Tank

Compressors are designed to accumu-

late moisture in the air tank instead of in 

your air stream.

We recommend draining air tank weekly to remove moisture. It is not uncom-

mon to have brown/rust colored water in tank as the inside of the tank is bare 

steel to eliminate any coating delamination. This will ultimately disappear as a 

film of oil will coat inside of tank during use (see page 9).

Unit Will Not 

Reach 145 PSI, 

Shuts Off Early

Defective Pressure gauge.

Replace pressure gauge with known good gauge and retest unit. If gauge is 

accurate replace Pressure Switch #32207.

Defective Pressure Switch  

(On/Off switch).

Replace Pressure Switch #32207.

Sludge in Oil 

Tank and On 

Dipstick

Light, intermittent use, operation 

in warm, damp locations, or during 

high humidity weather conditions will 

contribute to the formation of excess 

condensation in the system.

Drain and replace oil with 2 qts #31718 Eastwood Scroll Compressor Oil.
Replace Oil Filter #31715.
Replace Moisture Filter #31716.
See Monthly Maintenance Guide regarding Moisture Draining of oil tank.
