Safety Warnings Specific for
Grinding and Abrasive
Cutting-Off Operations:
Use only wheel
recommended for your power tool and the
specific guard designed for the
wheel.
Wheels
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 operator from broken wheel
fragments and accidental contact with wheel.
Wheels must
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.
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.
When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless
types that are
selected
for which the
be used only for
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.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
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 and
near the edge of the workpiece on both sides of
the wheel.
Use extra caution when making a "pocket
cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
Do not use type 1 abrasive wheels designed
for straight grinding.
Do not attempt to cut large stock or sheets
of metal as this machine is not designed to
be a dedicated cut-off machine.
Safety Warnings Specific for
Sanding Operations:
Do not use excessively oversized sanding
disc paper. Follow manufacturer's
recommendations, when selecting sanding
paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard
and may cause snagging, tearing of the disc or
kickback.
Safety Warnings Specific for Wire
Brushing Operations:
Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
excessive load to the brush. The wire
bristles can easily penetrate light clothing
and/or skin.
If the use of a guard is recommended for
wire brushing, do not allow any
interference of the wire wheel or brush with
the guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal
forces.
