m. Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
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
o. Do not operate the power tool near flammable
materials.
p. Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in

Causes and Operator Prevention of Kickback
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
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
Kickback is the result of 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 reaction or
b. Never place your hand near the rotating accessory.
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
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
e. Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent kickback
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
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 the operator from broken wheel
fragments, accidental contact with wheel and sparks that
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
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
e. Do not use worn down wheels from larger power tools.
Wheel intended for larger power tool is not suitable for the
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
b. Do not position your body in line with and behind the
rotating wheel.
When the wheel, at the point of operations,
is moving away from your body, the possible kickback may
c. When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the
power tool 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
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
e. Support panels or any oversized workpiece to minimize
the risk of wheel pinching and kickback.
Large
workpieces tend to sag under their own weight. Supports
must be placed under the workpiece near the line of cut
