Begin with coarse grit discs for fast, rough material removal. Move to a
medium grit paper and finish with a fine grit disc for optimal finish.

1. Allow the tool to reach full speed before touching tool to the
work surface.
2. Apply minimum pressure to work surface, allowing the tool to
operate at high speed. Sanding rate is greatest when the tool
operates at high speed.
3. Maintain a 5˚ to 15˚ angle between
the tool and work surface. The san ding
disc should contact approximately one
inch of work surface.
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
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.
CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
16 - 30 grit
36 - 80 grit

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
WARNING: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or
accessories. Before reconnecting the tool, turn the switch on
and off as previously described 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.
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
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 backward 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.
