Diamond cup wheels should be carefully select-
ed in order to use the grinder most efficiently.
Wheels vary in type of material they are de-
signed to remove and how aggressively they will
remove material. The correct wheel to use is de-
termined by the job.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Hold the tool with two hands and keep dia-
mond wheel flat on the work surface.
3. Apply minimum pressure, allowing the tool to
operate at high speed. Removal rate is great-
est when the tool operates at high speed.
4. Continuously move the tool at a moderate
speed to avoid creating gouges in the work
surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotat-
ing before laying it down.
Tip: For optimal dust collection, all sides of the
surfacing dust collection guard must stay in con-
tact with the surface and the surfacing guard
must be connected to a vacuum. A dull diamond
wheel can be sharpened by briefly surfacing an
abrasive material (eg. sand stone).
Sanding
Sanding discs range in grit from 16 (very course)
to 180 (very fine). They also vary in size and
spacing of grit.
OPEN COAT (type H) is used for soft materials
and on paint and varnish, CLOSED COAT (type
K) is used for metal, hardwood, stone, marble
and other materials. To obtain best results, se-
lect sanding discs carefully. Many jobs require
the use of several grit sizes and at times both
open coat and closed coat discs are required
to complete the job. See chart for application
examples.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work sur-
face, allowing the tool to operate at high
speed. Sanding rate is greatest when the
tool operates at high speed.

Operating Instructions
3. Maintain a 10° to 15° angle between the tool
and work surface, (Fig. 20).
Fig. 20
the disc comes in contact with the work, a vio-
lent thrust to the side may result.
4. Continuously move the tool at a moderate
speed to avoid creating gouges in the work
surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotat-
ing before laying it down.
Tip: Guide the disc with crisscross strokes. Do
not use a circular motion as this makes swirl
marks.
Operation: Refinishing painted wood or metal surfaces.
To remove paint and to smooth
surface irregularities.
To smooth the rough sanding.
To remove scratches left by
previous discs.
To smooth surfaces for painting,
polishing or waxing.
