Before using a grinding
wheel, be certain that its
maximum safe operating speed is not
exceeded by the nameplate speed of the
grinder. Do not exceed the recom mended
wheel diameter.
"!&"
Grinding wheels should be carefully selected in
order to use the grinder most efficiently.
Wheels vary in type of abrasive, bond,
hardness, grit size and structure. The correct
type of wheel to use is determined by the job.
Use disc grinding wheels for fast grinding of
structural steel, heavy weld beads, steel
casting, stainless steel and other ferrous
metals.
!# "
Efficient grinding is achieved by controlling the
pressure and keep ing the angle between
wheel and workpiece at 10° to 15°. If the wheel
is flat, the tool is difficult to control. If the angle
is too steep, the pressure is concentrated on a
small area causing burning to the work
surface.
Excessive or sudden pres-
sure on the wheel will slow
grinding action and put dangerous stresses on
the wheel.
When grinding with a new wheel be certain to
grind while pulling tool backwards until wheel
becomes rounded on its edge. New wheels
have sharp corners which tend to “bite” or cut
into work piece when pushing forward.

Using the optional type 1 wheel guard
(supplied with 1812PSD only), it is possible
to perform limited cutting on small stock such
as metal tubes, piping or rebar. When
cutting, work with moderate feed, adapted to
