MAINTAINING THE PNEUMATIC TOOL
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:
Use only Genuine OEM replacement parts.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or equivalent
on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on all moving
surfaces and pivots. After reassembly add a few drops of BOSTITCH 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.
