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.
