they bend or twist while the tool is being
used to do cut-off work or deep grinding.
To reduce the risk of serious injury, limit
the use of these wheels with a standard
Type 27 guard to shallow cutting and
notching (less than 13 mm [1/2"] in
depth). The open side of the guard must
be positioned away from the operator.
For deeper cutting with a cut-off wheel,
use a closed Type 1 guard. Please
refer to the Grinding and Cutting
Accessory Chart at the end of this
section to see other accessories that can
be used with these grinders.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work surface,
allowing the tool to operate at high speed.
Grinding rate is greatest when the tool operates
at high speed.
3. Position yourself so that the open-underside of
the wheel is facing away from you.
4. Once a cut is begun and a notch is established
in the workpiece, do not change the angle
of the cut. Changing the angle will cause the
wheel to bend and may cause wheel breakage.
Edge grinding wheels are not designed to
withstand side pressures caused by bending.
5. Remove the tool from the work surface before
turning the tool off. Allow the tool to stop
rotating before laying it down.
WARNING: Do not use edge grinding/
cutting wheels for surface grinding
applications because these wheels
are not designed for side pressures
encountered with surface grinding. Wheel
breakage and serious personal injury
may result.
Mounting and Using Wire Brushes
and Wire Wheels
Wire wheels and brushes can be used for
removing rust, scale and paint, and for smoothing
irregular surfaces.
NOTE: Please refer to Precautions To Take When
Wire Brushing Paint.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to work surface,
allowing the tool to operate at high speed.
Material removal rate is greatest when the tool
operates at high speed.
3. Maintain a 5° to 10° angle between the tool
and work surface for wire cup brushes.
4. Maintain contact between the edge of the
wheel and the work surface with wire wheels.
5. Continuously move the tool in a forward and
back motion to avoid creating gouges in the
work surface. Allowing the tool to rest on the
work surface without moving, or moving the
tool in a circular motion causes burning and
swirling marks on the work surface.
6. Remove the tool from the work surface before
turning the tool off. Allow the tool to stop
rotating before setting it down.
CAUTION: Use extra care when
working over an edge, as a sudden
sharp movement of grinder may
be experienced.
Using Cutting Wheels
WARNING: Do not use edge grinding/
cutting wheels for surface grinding
applications because these wheels
are not designed for side pressures
encountered with surface grinding. Wheel
breakage and injury may result.
1. Allow tool to reach full speed before touching
tool to work surface.
2. Apply minimum pressure to work surface,
allowing tool to operate at high speed. Cutting
rate is greatest when the tool operates at
high speed.
3. Once a cut is begun and a notch is established
in the workpiece, do not change the angle
of the cut. Changing the angle will cause the
wheel to bend and may cause wheel breakage.
4. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating
before setting it down.
Precautions To Take When Wire
Brushing Paint
1. Wire brushing of lead based paint is NOT
RECOMMENDED due to the difficulty of
controlling the contaminated dust. The greatest
danger of lead poisoning is to children and
pregnant women.
2. Since it is difficult to identify whether or not a
paint contains lead without a chemical analysis,
we recommend the following precautions when
wire brushing any paint:
