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
accessory may spin off possibly resulting
ininjury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate
the spindlefurther.

SURFACE GRINDING WITH GRINDING WHEELS
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. Maintain a 20° to 30° angle between the tool
and worksurface.
4. Continuously move the tool in a forward and
back motion to avoid creating gouges in the
worksurface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating
before laying itdown.
EDGE GRINDING WITH GRINDING WHEELS
WARNING: Wheels used for cutting and
edge grinding may break or kickback if
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
