MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool;
3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work area,
as accidental actuation may occur, possibly causing injury.
REPLACEMENT PARTS:
BOSTITCH 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
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.
TRIGGER VALVE REMOVAL:
1. Remove the two trigger valve pins as well as the secondary trigger and it’s spring.
2. Remove the trigger valve (with primary trigger still attached to it).
