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 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. 14)

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. 14

 

 

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

5˚–15˚

 

tool and work surface. The sanding

 

 

 

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 or M14 depending on the spindle of the tool. 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.

NOTICE: 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.
