EDGE GRINDING WITH GRINDING WHEELS (FIG. 10)
WARNING
: Wheels used for cutting and edge
FIG. 10
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 62–64 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, 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. 11)
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
5˚–10˚
FIG. 11
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. 12)
NOTE:
Guard may be removed when using sanding backing pads.
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

(R) on the spindle.
2. Place the sanding disc (Q) on the backing
pad (R).
3. While depressing the spindle lock button,
thread clamp nut (P) 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 disc while depressing the spindle lock button.
