To change compressor oil and filter:

.The engine oil drain and compressor oil

drain hoses are located together in the base. Be sure to select the correct hose when draining compressor oil.

.Be sure o-rings at oil drain and oil fill fit- tings are in place before reinstalling caps.

Drain compressor oil while compressor is still warm.

Route compressor oil drain hose through hole in base. Remove compressor oil fill cap. Re- move cap from oil drain hose and drain oil into a suitable container. Reinstall oil drain hose cap. Tighten cap with wrench.

Remove filter by turning filter counterclock- wise. Remove filter. Apply thin coat of oil to gasket on new filter. Install new filter and turn clockwise until tight.
