Oil Maintenance
Check the oil periodically for clarity. Replace oil if it appears milky or if debris is present,
or every 6 months, or 100 hours of runtime, whichever comes first.
In harsh environments such as high heat or high humidity, you will need to replace the oil more frequently.
cAUTION! TO pREVENT INJURy FROM BURNS:
Allow Air compressor to cool before changing the oil.
1. Place a container under the Oil Drain Plug (36).
2. Remove the Oil Breather Plug to allow
air flow into the Crankcase.
3. Remove the Oil Drain Plug, allowing
the oil to drain into the container.
4. When the oil is completely drained from the Pump,
replace the Oil Drain Plug.
Draining Moisture from the Tank
The Drain Valve is located on the bottom of the
Tank. It must be used daily to release all trapped
air and moisture from the Tank. This will eliminate
condensation which can cause tank corrosion.
1. Turn the Power Switch OFF.
2. Place a collection pan under the Drain Valve.
3. Open the Drain Valve by moving the Drain
Valve Lever parallel with the valve, as shown
in drawing on the left side of Figure J.
4. When all the pressure and moisture has been
released, close the Drain Valve by moving the
Drain Valve Lever perpendicular to the valve, as
shown in the drawing on the right side of Figure J.
