cutting wheel, use a closed, Type 1 guard. See the chart on pages 5-6
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-under-
side of the wheel is facing away from you.
4. Once a cut is begun and a notch is estab-
lished 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.
USING CUTTING WHEELS
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.
1. Allow tool to reach full speed before touching tool to work sur-
face.
2. Apply minimum pressure to work surface, allowing tool to oper-
ate at high speed. Cutting rate is greatest when the tool oper-
ates at high speed.
3. 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 or kick back.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
SURFACE FINISHING WITH SANDING FLAP DISCS
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.
USING SANDING BACKING PADS
Choose the proper grit sanding disc for your application. Sanding
discs are available in various grits. Coarse grits yield faster material
removal rates and a rougher finish. Finer grits yield slower material
removal and a smoother finish.
Begin with lower grit discs for fast, rough material removal. Move to
a medium grit discs and finish with a fine grit disc for optimal finish.
