operates athigh speed.
3.Maintain a 5°to 15 °angle between thetoolandworksurface.
The sanding disc should c ontact approximately one inch ofwork
surface.

Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. Use only wire brushes or wheels
provided with a 5/8"-11 threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
i_ CAUTION: Wear work gloves when handling wire brushes and
wheels. They can become sharp.
i_,CAUTION: Wheel or brush must not touch guard when mounted
or while in use. Undetectable damage could occur to the accessory,
causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE BRUSHES AND WIRE WHEELS
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.
i_ CAUTION: Failure to properly seat the wheel hub before turning
the tool on may result in damage to tool or wheel
USING WIRE CUP BRUSHES AND WIRE WHEELS
(FIG. 15, 16)
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 FIG.15
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.
