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.
j. 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
k. 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.
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.
FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS
KICKBACK AND RELATED WARNINGS
f
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.
f
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.
f
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.
