MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
REPLACEMENT PARTS:
B
OSTITCH 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 “O”-LUBE or
e
quivalent 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
a
ir line fitting before testing.
AIR SUPPLY-PRESSURE AND VOLUME:
A
ir 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.
