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 1 for the recommended accessories and connection order.
