Oil
Drain tank to release air pressure before removing the oil
fill cap or oil drain plug.
Checking
1. Remove the oil fill plug (A). The oil level should be even
with the top of the fill hole and no lower than 6 threads
from the top of fill hole.
2. If needed, slowly add oil until it reaches the top of fill hole.
NOTE: Use an oil specifically formulated for use in an air com-
pressor, such as Sears 9-16426 air compressor oil.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and drain oil into a suitable container.
3. Replace the oil drain plug (B) and tighten securely
4. Slowly fill crankcase to the top of the fill hole. Crankcase capacity is 16
fluid ounces (473.2 ml).
Overfilling with oil will cause premature compressor fail-
ure. Do not overfill.
5. Replace oil fill plug (A) and tighten securely.

To Drain Tank
1. Turn off engine.
2. Remove the air tool or accessory.
3. Pull ring on safety valve allowing air to bleed from the tank until tank pres-
sure is approximately 20 psi. Release safety valve ring.
4. Drain water from air tank by opening drain valve (counter-clockwise) on
bottom of tank.
Water will condense in the air tank. If not drained, water
will corrode and weaken the air tank causing a risk of air
tank rupture.
5. After the water has been drained, close the drain valve (clockwise). The air
compressor can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, then reinstalled.
