1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the air hose along a safe route 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. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be hazardous objects
(such as utility lines or foreign objects) nearby
that will present a hazard while working.

The contact actuation mechanism allows rapid placement of fasteners. The Tool should only actuate if the
Workpiece Contact is pressed against the workpiece and the Trigger is pulled. It should actuate again if the Trigger
is released and pulled OR if the Workpiece Contact is lifted and pressed against the workpiece again. The Tool
should not actuate if the Workpiece Contact is not pressed against an object. O&8$,4$%F4$',$"&8%#.&'79%&87[%+*%
