FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
a) This power tool is intended to function as a sander,
wire brush or polisher. Read all safety warnings,
instructions, illustrations and specifications provided
with this power tool.
Failure to follow all instructions
listed below may result in electric shock, fire and/or
serious injury.
b) Operations such as grinding 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.
c) Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safe operation.
d) 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 fly apart.
e) 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.
f) The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of
the power tool. Accessories with arbour 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.
g) 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.
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 flying debris
generated by various operations. The dust mask or
respirator must be capable of filtrating 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 fly 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 shock the
operator.
k) Position the cord clear of the spinning accessory. lf
you lose control, the cord may be cut or snagged and
your hand or arm may be pulled into the spinning
accessory.
l ) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, 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 at the point of the binding.
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 firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start-up. The operator can control torque reactions
or kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power
tool will move if kickback occurs.
Kickback will propel
the tool in direction opposite to the wheel's movement at
the point of snagging.
d) 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.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
