2.Route the air hose along a safe path to reach the work area without creating a tripping hazard or exposing the air hose to possible damage. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.

3.There must not be hazardous objects (such as utility lines or foreign objects) nearby that will present a hazard while working.

Contact Safety Trip (Bump Fire)

Mechanism Definition

The Red trigger enables a contact safety trip (or bump fire) mechanism, which allows rapid fire. 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.
