MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
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.
