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.
l)
Always hold the tool firmly 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.
m) 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.
n) 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.
o) 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.
p) 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.
q) 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.
r)
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.
s) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
t)
Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
u)
Instruction that the maximum recommended diameter
of mounted wheels, threaded cones and plugs shall not
exceed 55 mm and that the maximum recommended
diameter of sanding accessories shall not exceed 80
mm

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 firm 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 files, 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 file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the groove and
you could lose control of the tool.
