CAUTION

When pressure is applied to the oil pump, the handle may extend rapidly.

Verify the Compressor Module pressure is 0 psig before removing the second-stage oil separator.

Note

One full stroke oil pump of the handle dispenses 1.6 oz. (47ml) of oil. Move the pump handle slowly using long, slow, full strokes.

Note

The hose fittings contain a core depressor that opens the Schrader valve when the fittings are attached. A backseating control valve can be used to open the Schrader valves on the Compressor Module.

When the knob is turned fully counterclockwise, the core depressor is retracted and the backseating control valve can be installed on a Schrader valve without loss of oil.

When the knob is turned clockwise, the core retractor is extended, opening the Schrader valve.
