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 (FIG. 1, 13)
NOTE: Use of a guard with sanding discs
that use backing pads, often called fiber
resin discs, is not required. Since a guard
is not required for these accessories, the
guard may or may not fit correctly if used.
WARNING: Proper guard must be
reinstalled for grinding wheel, cutting
wheel, sanding flap disc, wire brush or
wire wheel applications after sanding
applications are complete.
1. Place or appropriately thread backing
pad (P) on the spindle.
2. Place the sanding disc (Q) on the
backing pad (P).
3. While depressing spindle lock (D), thread clamp nut (R) 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.

Edge grinding/cutting with a Type 1 wheel requires usage of a Type 1
guard.
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 if the wheel label has forbidden such use
because these wheels are not designed for side pressures
encountered with surface grinding. Wheel breakage and serious
personal injury may result.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 10)
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. Maintain a 20° to 30° 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.
EDGE GRINDING WITH GRINDING WHEELS (FIG. 11)
CAUTION: Wheels used for edge grinding and cutting may break
or kick back if they bend or twist while the tool is being used. In all
edge grinding/cutting operations, the open side of the guard must be
positioned away from the operator. Edge grinding/cutting with a
Type27 wheel must be limited to shallow cutting and notching—less
than 1/2" (13mm) in depth when the wheel is new. Reduce the depth
of cutting/notching equal to the reduction of the wheel radius as it
20˚-30˚
