SHOCK, OR INJURY TO
PERSONS
WARNING – When using tools, basic
precautions 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 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.
CAUTION, used with
the safety alert

situation which, if not avoided,
could result in minor or moderate
injury.

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.
i. Risk of Electric Shock. This tool 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.
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 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.
d. Remove adjusting keys and 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.
e. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpected
situations.
j. Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators. There is an
increased risk of electric shock if your
body is grounded.
k. Explore the workpiece to avoid
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
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 is able to 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. 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 ANSI-approved safety
goggles.
h. Always wear hearing
protection when using the
tool. Prolonged exposure to
high intensity noise is able to
cause hearing loss.
c. Do not use the tool if the switch does
not turn the tool on or off. Any tool that
cannot be controlled with the switch is
dangerous and must be repaired.
d. Disconnect the tool from the
air source before making any
adjustments, changing accessories,
or storing the tool. Such preventive
safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the air supply, safely
discharge any residual air pressure, and
release the throttle and/or turn the switch
to its off position before leaving the work
area.

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.
f. Maintain the tool with care. Keep a
cutting tool sharp and clean. A properly
maintained tool, with sharp cutting edges
reduces the risk of binding and is easier
to control.
g. Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that affects
the tool’s operation. If damaged,
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.
compressed air at the rated pressure or
within the rated pressure range as
marked on the tool. Always verify prior to
using the tool that the air source has
been adjusted to the rated air pressure
or within the rated air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled gas
as an air source for the tool. Such
gases are capable of explosion and
serious injury to persons.

Safety Warnings Common for
Grinding, Sanding, Wire Brushing,
Polishing, or Abrasive Cutting-Off
Operations
1. This power tool is intended to
function as a sander and polisher.
Read all safety warnings, instructions,
illustrations and specications
provided with this power tool. Failure
to follow all instructions listed below
may result in electric shock, re and/or
serious injury.
2. Operations such as grinding, wire
brushing, or cutting-off are NOT
recommended to be performed with
this power tool. Operations for which
the power tool was not designed may
create a hazard and cause personal
injury.
3. Do not use accessories which
are not specically designed
and recommended by the tool
manufacturer. Just because the
accessory can be attached to your power
tool, it does not assure safe operation.
4. The rated speed of the accessory
must be at least equal to the
maximum speed marked on the power
tool. Accessories running faster than
their RATED SPEED can break and y
apart.
5. The outside diameter and the
thickness of your accessory must
be within the capacity rating of
your power tool. Incorrectly sized
accessories cannot be adequately
guarded or controlled.
6. The arbor size of wheels, anges,
backing pads or any other accessory
must properly t the spindle of the
power tool. Accessories with arbor
holes that do not match the mounting
hardware of the power tool will run out
of balance, vibrate excessively and may
cause loss of control.
7. Do not use a damaged accessory.
Before each use inspect the
accessory such as abrasive wheels
for chips and cracks, backing pad
for cracks, tear or excess wear,
wire brush for loose or cracked
wires. If power tool or accessory
is dropped, inspect for damage or
install an undamaged accessory.
After inspecting and installing an
accessory, position yourself and
bystanders away from the plane of
the rotating accessory and run the
power tool at maximum no-load speed
for one minute. Damaged accessories
will normally break apart during this test
time.
8. Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety
glasses. As appropriate, wear dust
mask, hearing protectors, gloves
and workshop apron capable of
stopping small abrasive or work piece
fragments. The eye protection must
be capable of stopping ying debris
generated by various operations.
