Air Connection

1.You will need a Union fitting (sold separately) before you can connect your Die Grinder to an air compressor.

2.Attach the Union fitting to the HOSE ADAPTER (1) and tighten.

3.Attach an Air Coupler (sold separately) to the Union fitting if desired. This is a useful ac- cessory as it allows quick-coupling action when using a variety of tools with the same air compressor.

4.Your Die Grinder is ready for use.

OPERATION

Setup

Frequent, but not excessive, lubrication is required for best performance. Oil added through the airline connection will lubricate internal parts. An automatic airline oiler is recommended but oil may be added manually before every operation or after about 1 hour of continuous use. Only a few drops of oil at a time are necessary. Too much oil will collect inside the tool and be blown out during the exhaust cycle. ONLY USE PNEUMATIC TOOL OIL. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals in the tool.

Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/oiler for better performance and longer life. The filter must have adequate flow capacity for the specific application. Consult the manufacturer’s instructions for proper maintenance of your filter.

The connector on the tool must not hold pressure when the air supply is disconnected. If the wrong fitting is used, the tool can remain charged with air after being disconnected and still be able to drive a fastener. See Figure 5 for the recommended accessories and connection order.
