EDGE GRINDING WITH GRINDING WHEELS (FIG. 12)
_ CAUTION: 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"
(12.7 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.
See the chart on page 11 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, 13}
1. Allow the tool to reach full speed before touching the tool to the
work surface.
2. Apply minimum pressure to work FIG. 13
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
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, 14}
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 (R) on the spindle.
2. Place the sanding disc (S) on the backing pad.
