2.Unplug the cord from the outlet.

3.Turn the regulator knob counterclockwise until it is fully closed. Ensure that the regulated pressure gage reads 0 PSI.

3.Remove the hose and accessory.

4.Drain the air tanks.

5.Allow the compressor to cool down.

6.Wipe compressor clean and store in a safe, non-freezing area.

Maintenance

The following procedures must be followed when maintenance or service is performed on the air compressor.

1.Turn off the compressor.

2.Disconnect cord from electrical outlet.

3.Drain tanks.

4.Allow the compressor to cool down before starting service. NOTE: All compressed air systems contain maintenance parts (e.g. lubricating oil, filters, separators) which are periodically replaced. These used parts may be, or may contain, substances that are regulated and must be disposed of in accordance with local, state, and federal laws and regulations.

NOTE: Take note of the positions and locations of parts during disassembly to make reassembly easier. The assembly sequences and parts illustrated may differ for your particular unit.

NOTE: Any service operations not included in this section should be performed by authorized service personnel.
