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 and abrasive cutting-off opera-
tions:
▶
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.
Additional safety warnings specific for abrasive cutting-off operations:
▶
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.
