be positioned away from the operator. For deeper cutting with a
Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart on
page 8 for more information. Type 1 guards are available at extra
cost from your local dealer or authorized service center.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work
surface, allowing the tool to operate at
high speed. Grinding rate is greatest
when the tool operates at high speed.
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 backward 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
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.
CAUTION: Proper guard must be reinstalled for grinding wheel,
sanding flap disc, wire brush or wire wheel applications after
sanding applications are complete.
1. Place or appropriately
pad backing (R) on the spindle.
2. Place the sanding disc (S) 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 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
Choose the proper grit sandpaper for your application. Sandpaper is
available in various grits. Coarse grits yield faster material removal
5˚-10˚
rates and a rougher finish. Finer grits yield slower material removal
and a smoother finish.
