English 1. Place or appropriately thread backing FIG. 12 M pad (L) on the spindle. E 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 sanding disc and backing pad. 4. Tighten the clamp nut by hand. Then depress the spindle lock button while turning the sanding disc until the L 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. Coarse 16 - 30 grit Medium 36 - 80 grit Fine Finishing 100 - 120 grit Very Fine Finishing 150 - 180 grit 1. Allow the tool to reach full speed before touching tool to the work surface. 2. Apply minimum pressure to work FIG. 13 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 sanding 5˚-15˚ 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. 14

when the tool operates at high speed.

4. Move the tool constantly in a straight line to prevent burning and

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.
