INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using tools, basic pre-
cautions should always be followed,
including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before using the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in explo-
sive atmospheres, such as in the
presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
c. Keep bystanders, children, and
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are do-
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inuence of drugs, alcohol, or medica-
b. Dress properly. Do not wear loose
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
parts.
c. Avoid unintentional starting. Be
sure the trigger is released before
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 pressed.
d. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpected 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 with
side shields.
g. Always wear hearing
protection when using
the tool. Prolonged expo-
sure to high intensity noise
is able to cause hearing loss.
h. Do not attach the hose or tool to
your body. Attach the hose to the
structure to reduce the risk of loss of
balance if the hose shifts.

i. Always assume that the tool con-
tains fasteners. Do not point the tool
toward yourself or anyone whether it
contains fasteners or not.
e. Store the tool when it is idle out of
reach of children and other untrained persons. A tool is dangerous
in the hands of untrained users.
j. WARNING – Do not re fastener on
top of another fastener. This is able
to cause the fastener to be deected
and hit someone, or cause the tool to
react and result in a risk of injury to
persons.
k. WARNING – Remove nger from
the trigger when not driving fasteners. Never carry the tool with
nger on trigger, the tool is able to re
a fastener.
Tool use and care
a. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and can lead to
loss of control.
b. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
f. Maintain the tool with care. A prop-
erly maintained tool reduces the risk
of binding and is easier to control.
g. Check for misalignment or bind-
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.
h. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
i. Use only those fasteners listed
in the Specications chart of this
manual. Fasteners not identied for
use with this tool by the tool manufacturer are able to result in a risk
of injury to persons or tool damage
when used in this tool.
c. Do not use the tool if the trigger
does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must not be used until repaired.
d. Disconnect the tool from the air
source before making adjustments, doing tool maintenance,
clearing jams, touching the safety
nosepiece, leaving work area,
loading, or unloading the tool.
Such precautionary measures reduce
the risk of injury to persons.
