10) 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 .
11) 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 .
12) 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 .
13) 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 .
14) 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 .
15) Do not operate the power tool
near flammable materials. Sparks
could ignite these materials .
16) 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,
backing pad, brush or any other
accessory . Pinching or snagging causes
rapid stalling of the rotating accessory
12 GB
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 .
1)
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 .
2)
Never place your hand near the
rotating accessory. Accessory
may kickback over your hand .
3)
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 .
4)
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 .
