4. Move the tool constantly in a straight
line to prevent burning and swirling of 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.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder spin-
dle without the use of flanges. Use only wire brushes or wheels pro-
vided with a 5/8"-11 threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
.&CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
CAUTION: Wheel or brush must not touch guard when mounted
or while in use. Undetectable damage could occur to the accesso_
causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or acces-
sories. Before reconnecting the tool, depress and release the
paddle switch to ensure that the tool is off.
1. Thread the wheel on the spindle by hand.
2. Depress spindle lock button and use a wrench on the hub of the
wire wheel or brush to tighten the wheel.

3. To remove the wheel, reverse the above procedure.
A CAUTION: Failure to properly seat the wheel hub before tuming
the tool on may result in damage to tool or wheel.
USING WIRE CUP BRUSHES AND WIRE WHEELS
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
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.
i&CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.
