Tool Operation Check; Maintaining The Pneumatic Tool - Bostitch SL1838BC Operation And Maintenance Manual

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.
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.
