Sample Air Line Setup

5.Connect a regulator valve, an in-line shut off valve and a 1/4” NPT air hose (all sold separately) to the Quick Coupler (76). The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.

Note: An in-line shutoff ball valve is an important safety device because it controls the air supply even if the air hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly.

6.Depending on the tool which you will be using with this compressor, you may need to incorporate additional components, such as an in-line oiler, a filter, or a dryer (all sold separately).

Consult your air tool’s manual for needed accessories.

Checking the Oil

1.Check the oil level before operation. Fill the Pump Crankcase (39) with premium quality SAE 30-weight, non- detergent air compressor oil.

IMPORTANT: Running the Air Compressor with the incorrect amount of oil will cause damage to the equipment and void the warranty. To prevent damage, do not use with overfilled or low oil. Slowly fill to full line, wait 2 minutes and fill back up to full line. Compressor has small passages that will fill slowly.

2.The oil level should be at the center of the “full” level on the oil level sight glass, as shown in Figure 5. Add oil as needed to maintain this level. Do not let the oil level go below the center dot (LOW as shown above) and do not overfill the oil so that it is above the center dot (OVERFILL as shown above) on the sight glass.

3.To add oil:

a.Remove the Oil Plug (37).

b.Using a funnel to avoid spills, pour enough oil into the Pump Crankcase (39) to reach the “full” level in the Oil Sight Glass (33).
