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.
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.
Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Do not use accessories that require liquid cool-
ants. 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 acces-
sory'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
the 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.
Maintain a firm grip on the power tool and posi-
tion 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.
Never place your hand near the rotating acces-
sory. The accessory may kickback over your hand.
Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in the direction opposite
to the wheel's movement at the point of snagging.
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.
Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety warnings specific for grinding and abrasive
cutting off operations
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 ade-
quately guarded and are unsafe.
The grinding surface of the 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.
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, acciden-
tal contact with wheel and sparks that could ignite
clothing.
Wheels must be used only for recommended
applications. For example: Do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding; side forces
applied to these wheels may cause them to shatter.
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.
Do not use worn down wheels from larger
power tools. A wheel intended for a larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
Additional safety warnings specific for abrasive
cutting off operations
Do not "jam" the cut-off wheel or apply exces-
sive pressure. Do not attempt to make an exces-
sive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twist-
ing or binding of the wheel in the cut and the pos-
sibility of kickback or wheel breakage.
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 spin-
ning wheel and the power tool directly at you.
When the 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 corrective action to
eliminate the cause of wheel binding.
