DeWalt D28065 Instruction Manual page 17

Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart on
page 10 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 (FIG. 12)
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
FIG. 11
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 (FIG. 13)
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 thread backing pad (Q) on the spindle.
2. Place the sanding disc (P) 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 (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.
