Further safety instructions for all operations
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.
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.
Never place your hand near the rotating accessory. Accessory may kickback over your
hand.
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.
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
frequent kickback and loss of control.
Safety Warnings Specific for Grinding:
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.
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.
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.
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.
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. Wheel intended for larger power
tool is not suitable for the higher speed of a smaller tool and may burst.
