k) 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.
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 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 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.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations
a) Use only wheel types that are recommended for your power tool and the
specific guard designed for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded and are unsafe.
b) The guard must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is exposed towards the
operator. The guard helps to protect operator from broken wheel fragments and
accidental contact with wheel.
c) Wheels must be used only for recommended applications. For example: do
not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended
for peripheral grinding, side forces applied to these wheels may cause them to
shatter.
d) Always use undamaged wheel flanges that are of correct size and shape for
your selected wheel. Proper wheel flanges support the wheel thus reducing the
possibility of wheel breakage. Flanges for cut-off wheels may be different from
grinding wheel flanges.
e) Do not use worn down wheels from larger power tools. Wheel intended for
larger power tool is not suitable for the higher speed of a smaller tool and may
burst.
