ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inu-
ence of drugs, alcohol, or medica-
tion. A moment of inattention while
operating the tool increases the risk
of injury to persons.
Dress properly. Do not wear looseb.
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving

connecting to the air supply. Do not
carry the tool with your nger on the
trigger or connect the tool to the air
supply with the trigger on.

footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpect-
ed situations.
e. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
f. Always wear eye protec-
tion. Wear ANSI-ap-
proved safety goggles.

tains fasteners. Do not point the tool

ments, doing tool maintenance,
clearing jams, touching the safety,
leaving work area, loading, or un-
loading the tool. Such precautionary
measures reduce the risk of injury to
persons.
Store the tool when it is idle out ofe.
reach of children and other un-
trained persons. A tool is dangerous
in the hands of untrained users.
Maintain the tool with care.f. A prop-
erly maintained tool is more efcient
and reduces the risk of binding and is
easier to control.

ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
