EDGE GRINDING WITH GRINDING WHEELS (FIG. 11)
WARNING: Wheels used for cutting and edge grinding may break
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" in depth). The open side of the guard must be
positioned away from the operator. For deeper cutting with a Type1
cut-off wheel, use a closed, Type 1 guard. See the chart on page 9
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
FIG. 11
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 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.
