Metal Grinding
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 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.
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. Maintain a 10° to 15° angle between the
tool and work surface, (Fig. 18).
4. Continuously move the tool at a
moderate speed to avoid creating gouges
in the work surface.

Metal Cutting

this tool but is required when using a
cutting wheel. Cutting with a type 27 wheel
guard may not provide the operator sufficient
protection in the event of a wheel burst.
With this grinder it is possible to perform
cutting of limited small stock such as metal
tubes, piping or rebar. When cutting, work
with moderate feed, adapted to the material
being cut. When cutting profiles and square
bar, it is best to start at the smallest cross
section.
Always follow precautions for kickback.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. The tool should always be used in such way
that the sparks are directed away from
user.
3. Apply minimum pressure to the work
surface, allowing the tool to operate at high
speed. Cutting rate is greatest when the
tool operates at high speed.

5. Remove the tool from work surface
before turning tool off. Allow the tool to
stop rotating before laying it down.
pressure on the wheel
will slow grinding action and put
dangerous stresses on the wheel.
Tip: When grinding with a new wheel be
certain to grind while pulling tool
backwards until the wheel becomes
rounded on its edge. New wheels have
sharp edges which tend to "bite" or cut into
the work piece when pushed forward.
4. Do not exert side pressure onto the cutting
disc. Do not tilt or oscillate the tool as
wheel may burst, (Fig. 19).
5. Remove the tool from the work surface
before turning the tool off. Allow the tool to
stop rotating before laying it down.
