WARNING – When using tools, basic
precautions should always be
followed, including the following:
General
To reduce the risks of electric shock,
re, and injury to persons, read all the
instructions before using the tool.
Work area
Keep the work area clean and well a.
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
Do not operate the tool in b.
explosive 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.

Keep bystanders, children, and c.
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
Stay alert. Watch what you are a.
doing and use common sense
when operating the tool. Do not
use the tool while tired or under
the inuence of drugs, alcohol, or
medication. A moment of inattention
while operating the tool increases the
risk of injury to persons.
Dress properly. Do not wear loose b.
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.
Avoid unintentional starting. c.
Be sure the switch is off before
connecting to the air supply. Do not
carry the tool with your nger on the
switch or connect the tool to the air
supply with the switch on.
Remove adjusting keys and d.
wrenches before turning the tool
on. A wrench or a key that is left
attached to a rotating part of the tool
increases the risk of personal injury.
Do not overreach. Keep proper e.
footing and balance at all times.
Proper footing and balance
enables better control of the tool in
unexpected situations.
f. 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.
g. Always wear eye
protection. Wear ANSIapproved safety goggles.
h. Always wear hearing
protection when using
the tool. Prolonged
exposure to high intensity
noise is able to cause hearing loss.
Risk of Electric Shock. This tool i.
is not provided with an insulated
gripping surface. Contact with a
″live″ wire will also make exposed
metal parts of the tool ″live″ and
shock the operator.
Avoid body contact with grounded j.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Explore the workpiece to avoid k.
contact with hidden wiring.
Thoroughly investigate the workpiece
for possible hidden wiring before
performing work. Contact with live
wiring will shock the operator.
Tool use and care
Use clamps or another practical a.
way to secure and support the
workpiece to a stable platform.
