Maintaining The Pneumatic Tool - Bostitch RN46 Manuel D'instructions Et D'entretien

CAUTION: Remove all fasteners from tool before performing tool operation check.
1. 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.
2. 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.
3. 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 fastener. Release the trigger and cycle is complete.
CAUTION: THE TOOL WILL CYCLE EACH TIME THE TRIGGER INTERLOCK AND TRIGGER IS PULLED!
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 and lubricated. Use MAGNALUBE
or equivalent on all "O"-rings. Coat each "O"-ring with MAGNALUBE 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.
