It is most important that the sockets that are used are
specifically designated "impact wrench sockets." Sockets and
accessories which are made for hand use only will not stand up
to impact wrench use. They are subject to premature failure,
breaking and possibly causing injury. Impact type sockets
usually are identified by a black finish on the outside, and have
heavier section thickness.

Always wear safety goggles or safety glasses with side shields
complying with current national standard, and a full face shield
when needed. Use a dust mask in dusty work conditions. Wear
hearing protection during extended periods of operation.

Do not wear loose clothing, jewelry or any dangling objects that
may catch in rotating parts or accessories. Tie back long hair.

Never use a wire, soft pin or nail to hold the socket onto the
square spindle of the impact wrench. If the proper retaining device
on the tool is broken, the tool should be repaired.

Avoid excessive impacting, particularly on small bolt sizes. Small
bolts could easily be broken or the threads stripped. Over torquing
can cause premature failure of fasteners or other damage, and can
lead to accidents.

On applications where a low or critical level of torque is required, it
is recommended that you impact each fastener lightly, then perform
the final tightening with a hand torque wrench.

If your owner/operators manual recommends using wood boring bits
with an impact wrench, be sure to unplug the tool before changing,
the bits.

Do not use an impact wrench in wet or damp environments.
