Oil Maintenance
Check 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
rst. In harsh environments such as high heat or
high humidity, you will need to replace the oil more
frequently.
WARNING: Risk of personal injury hazard. Allow Air
Compressor to cool before changing the oil.
To drain the oil from the Pump Crankcase (39):
a. Place a container under the Drain Plug (35).
b. Remove the Oil Plug (37) to allow air ow into the
Pump.
c. Remove the Drain Plug, allowing the oil to drain
into the container.
d. When the oil is completely drained from the Pump,
replace the Drain Plug.
e. Fill the Pump with new compressor oil to the FULL
level on the Oil Sight Glass (33).
f. Replace and tighten the Oil Plug.
g. Discard the old oil according to local, state and
federal regulations.
Draining Moisture from the Tank
The Drain Valve (66) is located under the Tank (70).
It must be accessed daily to release all trapped
air and moisture from the Tank. This will eliminate
condensation which can cause tank corrosion.
Note: Do not open the Drain Valve so that more than four
threads are showing.
To empty the air and condensation:
a. Make sure the Power Lever of the compressor is
off.
b. Place a collection pan under the Drain Valve.
c. Unthread the Drain Valve two or three turns ONLY.
d. When all the pressure is released, close the Drain
Valve.
Air Filter Maintenance
Check the Air Filter weekly to see if it needs
replacement. If working in dirty environments,
you may need to replace the lter more often. To
replace the Air Filter:
a. Remove the Cover (1).
b. Remove the Air Filter (6).
c. Replace with a new Air Filter.
d. Replace the Cover.
