Fastener Functioning
Prior to learning the safe operating procedures for this
tool, it is important to understand how a powder‑actuated
fastener works. A powder‑actuated fastener is considered
to be a direct drive or forced entry type of fastener because
it is driven directly into the base material. The driving action
causes tremendous forces to be applied to the fastener.
D WALT powder‑actuated fasteners are specially designed
e
and manufactured to withstand the forces imposed during
the driving operation. Only fasteners manufactured or
supplied by D WALT should be used in this tool.
e
Suitable Base Material

WARNING: Failure to follow the warnings and
instruction may result in severe injury or death to the
tool operator and/or bystanders.
Powder‑actuated fasteners can be used successfully
in concrete, certain masonry materials, and A 36 steel,
but some materials are not suitable. Never guess when
fastening into base materials. Fasteners should never be
fired into hard or brittle materials such as cast iron, tile,
glass, or rock. These materials can easily shatter resulting
