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 work-
piece, 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 pres-
sures 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 it down.
MOUNTING SANDING BACKING PADS
CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or acces-
sories. Before reconnecting the tool, turn the switch on and off
as previously described to ensure that the tool is off.
CAUTION: Proper guard must be reinstalled for grinding wheel,
sanding flap disc, wire brush or wire wheel applications after sand-
ing applications are complete.
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.
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.
5˚-10˚
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.
