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 wheel to stop rotating before laying the tool down.
EDGE GRINDING WITH GRINDING WHEELS
(FIG. 12)
WARNING:
Wheels used for cutting and edge grinding may break
or kickback if they bend or twist while the tool is being used to do
cut-off work or deep grinding. To reduce the risk of serious injury, limit
the use of these wheels with a standard Type 27 guard to shallow
cutting and notching (less than 1/2" [13 mm] in depth). The open side
of the guard must be positioned away from the operator. For deeper
cutting with a Type 1 cut-off wheel, use a closed Type 1 guard. Refer
to pages 11–13 for more information.
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to the work surface,
FIG. 12
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 wheel to stop rotating before laying the tool 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
serious personal injury may result.
SURFACE FINISHING WITH SANDING FLAP DISCS (FIG. 13)
1. Allow the tool to reach full speed before
5˚–10˚
FIG. 13
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 wheel to stop rotating before laying the tool down.
MOUNTING SANDING BACKING PADS (FIG. 14)
NOTE:
Guard may be removed when using sanding backing pads.
WARNING:
Proper guard must be reinstalled
FIG. 14

R
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
(S) on the spindle.
2. Place the sanding disc (T) on the backing
pad (S).
3. While depressing the spindle lock button,
thread clamp nut (R) on spindle, piloting the
raised hub on the clamp nut into the center
of san ding disc and backing pad.
