DeWalt D28065 Instruction Manual page 18

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.
16 - 30 grit
36 - 80 grit
100 - 120 grit
150 - 180 grit

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 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.
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
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.
