30-weight, non-detergent, compressor oil before each use. Running the Air Compressor with no oil or low oil will cause damage to the equipment and void the warranty. To check the level of oil, make sure the Air Compressor is OFF. Then, observe the Oil Level Window (part #72). The level of oil should just reach the horizontal line as shown on the Oil Level Window. If the level of oil is below the horizontal line, remove the Oil Plug (part #78) and add new oil through the Oil Plug hole. Make sure not to overfill. The Air Compressor is designed to hold approximately 25 fluid ounces of oil. Then screw in the Oil Plug, being careful not to strip the threads.

(See Figure D.)

2.Turn the Air Outlet Valve (part #69) to its CLOSED position. Then connect a high pressure air hose (not included) equipped with a quick connector to the Air Outlet Valve. If using a water filter and oiler in series with the Air Outlet Valve of the Air Compressor, connect the other end of the air hose to the water filter and oiler and connect the water filter and oiler to the air tool being used. If not using a water filter and oiler, squirt several drops of air tool oil into the air intake plug of the air tool. Then, connect the other end of the air hose directly from the Air Outlet Valve of the Air Compressor to the air tool.
