POWER SOURCE

This tool is designed to operate on clean, dry, compressed air at regulated pressures between 70 and 120 PSI (Pounds per Square Inch)(4.8 to 8.3 BAR). The preferred system would include a filter, a pressure regulator, and an automatic oiler located as close to the tool as possible, within 15 ft/4.6 m is ideal.

All compressed air contains moisture and other contaminates that are detrimental to internal components of the tool. An air line filter will remove most of these contaminates and significantly prolong the life of the tool. If an in-line oiler is not available: place five or six drops of Porter-Cable Air Tool Oil into the tool’s air inlet at the beginning of each workday.

The tool is equipped with a 1/4" male “quick connector”. A 3/8" male “quick connector” is available from Porter-Cable and may be used in situations where a 1/4" supply line is not available. The tool must always be connected to the air supply with a coupling such that all pressure is removed from the tool when the coupling is disconnected.
