•Never clamp or tape the trigger or contact trip in an actuated position.
•Never leave a tool unattended with the air hose attached.
•Do not operate this tool if it does not contain a legible WARNING LABEL.
•Do not continue to use a tool that leaks air or does not function properly. Notify your nearest Porter cable representative if your tool continues to experience functional problems.

When working on air tools, note the warnings in this manual and use extra care evaluating problem tools.
Pusher spring (constant force spring). Caution must be used when working with the spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond its length, the end will come off the roller and the spring will roll up with a snap, with a chance of pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken to insure no permanent kinks are put in the spring as this will reduce the springs force.
REPLACEMENT PARTS:
PORTER CABLE replacement parts are recommended. Do not use modified parts or parts which will not give equivalent performance to the original equipment.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker
PORTER CABLE Air Tool Lubricant through the air line fitting before testing.
AIR SUPPLY-PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be slow operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing water and anything else that would prevent full volume flow of air to the tool.
