MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
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. Use Parker “O”-LUBE or equivalent on all “O”-
rings. Coat each “O”-ring with “O”-LUBE 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, swivel fittings, low points
containing water and anything else that would prevent full volume flow of air to the tool.
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.
“DIAL-A-DEPTH™” FASTENER CONTROL ADJUSTMENT
The DIAL-A-DEPTH™ Fastener Control adjustment feature provides close
control of the fastener drive depth; from flush with the work surface to
shallow or deep countersink. First, set the air pressure for consistent drive in
the specific work as described on page 4, then use the DIAL-A-DEPTH™
Fastener Control adjustment to give the desired depth of drive.
