SAFETY INSTRUCTIONS FOR
ALL OPERATIONS
SAFETY WARNINGS COMMON FOR GRINDING,
SANDING, WIRE BRUSHING, POLISHING, CARVING OR
ABRASIVE CUTTING-OFF OPERATIONS
a. This power tool is intended to function as a grinder,
sander, wire brush, polisher, carving or cut-off tool.
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.
b. 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.
c. The rated speed of the grinding accessories must be
at least equal to the maximum speed marked on the
power tool. Grinding accessories running faster than their
rated speed can break and y apart.
d. 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 controlled.
e. The arbour size of wheels, sanding drums or any other
accessory must properly t the spindle or collet of the
power tool. Accessories that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
f. Mandrel mounted wheels, sanding drums, cutters or
other accessories must be fully inserted into the collet
or chuck. If the mandrel is insufciently held and/or the
overhang of the wheel is too long, the mounted wheel may
become loose and be ejected at high velocity.
g. Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, sanding drum 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.
h. 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 workpiece fragments.
The eye protection must be capable of stopping ying
debris generated by various operations. The dust mask or
respirator must be capable of ltrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
i. Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken accessory may y away and cause injury beyond
immediate area of operation.
j. Hold power tool by insulated gripping surfaces only,
when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and could give
the operator an electric shock.
k. Always hold the tool rmly in your hand(s) during the
start-up. The reaction torque of the motor, as it accelerates
to full speed, can cause the tool to twist.
l. Use clamps to support workpiece whenever practical.
Never hold a small workpiece in one hand and the
tool in the other hand while in use. Clamping a small
workpiece allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes or tubing
have a tendency to roll while being cut, and may cause the
bit to bind or jump toward you.
m. Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your hand
or arm may be pulled into the spinning accessory.
n. Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your control.
o. After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other adjustment
devices are securely tightened. Loose adjustment devices
can unexpectedly shift, causing loss of control, loose
rotating components will be violently thrown.
p. Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.
q. Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
r. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
s. Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, sanding band, brush or any other accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a. Maintain a rm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if proper
precautions are taken.
b. Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.
c. Do not attach a toothed saw blade. Such blades create
frequent kickback and loss of control.
d. Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Feeding the tool in the wrong direction causes the
cutting edge of the bit to climb out of the work and pull the
tool in the direction of this feed.
e. When using rotary les, cut-off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself usually breaks.
When a rotary le, high-speed cutter or tungsten carbide
cutter grabs, it may jump from the groove and you could
lose control of the tool.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND
ABRASIVE CUTTING-OFF OPERATIONS
a. Use only wheel types that are recommended for your
power tool and only for recommended applications. For
example: do not grind with the side of a cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding,
