MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools.
CAUTION: 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:
Use only genuine BOSTITCH replacement parts. Do not use modified parts.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE,
Magnalube, or equivalent on all “O”-rings. Coat each “O”-ring with lubricant before assembling.
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, low points containing water and anything else that would prevent full volume flow of air to the
tool.
