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. 19).

Metal Cutting

A Type 1 wheel guard may
WARNING
not be included with 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 so 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.
4. Do not exert side pressure onto the cutting
disc. Do not tilt or oscillate the tool as wheel
may burst, (Fig. 20).
5. Remove the tool from the work surface
before turning the tool off. Allow the tool to
stop rotating before laying it down.
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
rotating before laying it down.
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.
