m) 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.
n) 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.
o) 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.
p) Do not operate the power tool near fl ammable
materials.
Sparks could ignite these materials.
q) 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 fi rm grip with both hands 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,
segmented diamond wheel with a peripheral gap
greater than 10 mm 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 specifi ed for your
power tool and the specifi c guard designed for the
selected wheel.
Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
b) The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
c) 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 the operator from broken
wheel fragments, accidental contact with wheel and
sparks that could ignite clothing.
d) Wheels must be used only for specifi ed 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.
e) Always use undamaged wheel fl anges that are of
correct size and shape for your selected wheel.
Proper wheel fl anges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be diff erent from grinding wheel fl anges.
f) Do not use worn down wheels from larger power
tools.
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
g) When using dual purpose wheels always use the
correct guard for the application being performed.
Failure to use the correct guard may not provide the
desired level of guarding, which could lead to serious
injury.
ADDITIONAL SAFETY WARNINGS
SPECIFIC FOR ABRASIVE CUTTING-
OFF OPERATIONS
a) Do not "jam" the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind
the rotating wheel.
When the wheel, at the point of operation, is moving
away from your body, the possible kickback may propel
the spinning wheel and the power tool directly at you.
c) When the wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold it motionless until the wheel comes to a
complete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in motion
otherwise kickback may occur.
Investigate and take corrective action to eliminate the
cause of wheel binding.
d) Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully re-enter
the cut.
The wheel may bind, walk up or kickback if the power
tool is restarted in the workpiece.
