OPERATING INSTRUCTIONS
1. Check to make sure the Tank’s Drain Valve (59), located at the bottom of the
Tank (50), is fully closed. (See Figure I.)
2. Turn the Air Outlet Valve (69) to its closed position. (See Figure G, next page.)
3. Connect an air hose (not included) to the Air Outlet Valve (69). Then, connect
the other end of the air hose to the pneumatic tool (not included) that is to be
used. (See Figure G.)
To Fill The Crankcase With Compressor Oil:
1. Make sure to put compressor oil (not included) in the Compressor’s crank-
case prior to its first use. Before each subsequent use, check the oil level.
Never run the Compressor with low or no compressor oil. Running the Compres-
sor with low or no oil will permanently damage the unit.
Note: Crankcase oil capacity is 25.3 ounces (750 ml). (See Figure F.)
2. The Oil Sight Glass (72) is used to determine if oil is needed. The oil level should
always be at the maximum level (at the red line on the Glass). (See Figure F.)
3. To fill the crankcase with oil, unscrew and remove the Oil Breather Cap (78). Add
a premium quality compressor oil into the oil fill hole until the level of oil reaches
the red line on the Oil Sight Glass (72). Do not overfill. Then thread the Oil
Breather Cap back into the oil fill hole, taking care not to strip the plastic threads
on the Oil Breather Cap. (See Figure F.)
