3. Position yourself so that the open-underside of the wheel is facing away from
you.
4. Once a cut is begun and a notch is established in the workpiece, do not change
the angle of the cut. Changing the angle will cause the wheel to bend and may
cause wheel breakage. Edge grinding wheels are not designed to withstand side
pressures caused by bending.
5. Remove the tool from the work surface before turning the tool off. Allow the tool
to stop rotating before laying it down.
WARNING: Do not use edge grinding/cutting wheels for surface grinding
applications because these wheels are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury may result.
SURFACE FINISHING WITH SANDING FLAP DISCS
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. Sanding rate is greatest when the tool operates at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool and
work surface.
4. Continuously move the tool in a forward and back
motion to avoid creating gouges in the work surface.
5. Remove the tool from work surface before turning
tool off. Allow the tool to stop rotating before laying
down.
MOUNTING SANDING BACKING PADS
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.
wire brush or wire wheel applications after sanding applications are complete.
USING SANDING BACKING PADS
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. Place or appropriately thread backing pad (Q) on the spindle.
2. Place the sanding disc (R) on the backing pad.
3. While depressing spindle lock, thread clamp nut (H) 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 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.

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 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.
