1. Place or appropriately thread backing
pad (L) on the spindle.
2. Place the sanding disc (M) on the
backing pad.
3. While depressing spindle lock, thread
the clamp nut (E) on spindle, piloting
the raised hub on the clamp nut into
the center of san ding disc and backing
pad.
4. Tighten the clamp nut by hand. Then
depress the spindle lock button while
turning the sanding disc until the
sanding disc and clamp nut are snug.
5. To remove the wheel, grasp and turn the backing pad and
sanding pad while depressing the spindle lock button.
USING SANDING BACKING PADS (FIG. 13)
Choose the proper grit sandpaper for your application. Sandpaper
is available in various grits. Coarse grits yield faster material removal
rates and a rougher finish. Finer grits yield slower material removal
and a smoother finish.
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.
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 CUP 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.
