Contact Safety Trip (Bump Fire) Mechanism Definition
The contact safety trip (or bump fire) mechanism allows rapid fire. The RED TRIGGER enables the
contact safety trip mechanism. The tool should only fire if the Safety Nosepiece is pressed against the
workpiece and the trigger is pulled. It should fire again if the trigger is released and pulled OR if the
safety is lifted and pressed against the workpiece again. The Tool should not fire if the Safety Nosepiece
is not pressed against an object. Contact safety trip / bump fire should only be enabled and used
by skilled operators who are aware of the hazards and use proper, safe work practices.
