instructions before operating the tool.
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the operator.
• Actuating tool may result in flying debris, collation material, or dust which
could harm operator's eyes. Operator and others in work area MUST wear safety
glasses with side shields. These safety glasses must conform to ANSI Z87.1
requirements (approved glasses have "Z87" printed or stamped
on them. It is the employer's responsibility to enforce the use of
eye protection equipment by the tool operator and other people in
the work area. (Fig. A)
• Always wear appropriate personal hearing and other protection
during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss. (Fig. A)
• Disconnect battery pack from the tool when not in use.
Always remove battery pack and remove fasteners from magazine before
leaving the area or passing the tool to another operator. Do not carry tool to
another work area in which changing location involves the use of scaffoldings,
stairs, ladders, and the like, with battery pack connected. Do not make
adjustments, perform maintenance or clear jammed fasteners while battery is in
place.
• Do not remove, tamper with, or otherwise cause the tool, trigger, trigger lock-off, or
contact trip to become inoperable. Do not tape or tie trigger or contact trip in the
ON position. Do not remove spring from contact trip. Make daily inspections for free
movement of trigger and contact trip. Uncontrolled discharge could result.

operating a power tool. Distractions can cause you to lose
control. When tool is not in use, it should be locked in a
safe place, out of the reach of children.
• Do not carry the tool from place to place holding the
trigger. Accidental discharge could result.
• Always use trigger lock-off when tool is not in immediate
