Tool Operation Check; Maintaining The Pneumatic Tool - Bostitch BT125 Manual De Operación Y De Mantenimiento

TOOL OPERATION CHECK:

CAUTION: Remove all fasteners from tool before performing tool operation check.
1. TRIGGER OPERATED TOOL:
A. With finger off the trigger, hold the tool with a firm grip on the handle.
B. Place the nose of the tool against the work surface.
C. Pull the trigger to drive. Release the trigger and cycle is complete.
CAUTION: THE TOOL WILL CYCLE EACH TIME THE TRIGGER IS PULLED!
2. CONTACT TRIP OPERATION:
A. With finger off the trigger, press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.
B. Hold the tool off the work surface, and pull the trigger.
THE TOOL MUST NOT CYCLE.
C. With the tool off the work surface, pull the trigger. Press the contact trip against the work surface.
THE TOOL MUST CYCLE.
D. Without touching the trigger, press the contact trip against the work surface,
then pull the trigger.
THE TOOL MUST CYCLE.
3. SEQUENTIAL TRIP OPERATION:
A. Press the contact trip against the work surface, without touching the trigger.
THE TOOL MUST NOT CYCLE.
B. Hold the tool off the work surface and pull the trigger.
THE TOOL MUST NOT CYCLE.
Release the trigger. The trigger must return to the trigger stop on the frame.
C. Pull the trigger and press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.
D. With finger off the trigger, press the contact trip against the work surface. Pull the trigger.
THE TOOL MUST CYCLE.

MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring
assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond
its length, the end will come off the roller and the spring will roll up with a snap, with a chance of
pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken
to insure no permanent kinks are put in the spring as this will reduce the springs force.
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.
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.
