Metal Cutting - Bosch GWX18V-13C Instrucciones De Funcionamiento Y Seguridad

Grinding
Before
wheel, be certain that its
maximum safe operating speed is not exceed-
ed 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 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 sur-
face, 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. 24).

Metal Cutting

A Type 41/1A wheel guard
may 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 cut-
ting of limited small stock such as metal tubes,
piping or rebar. When cutting, work with mod-
erate 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 sur-
face, allowing the tool to operate at high
speed. Cutting rate is greatest when the tool
operates at high speed.

Excessive or sudden pres-
sure on the wheel will slow
grinding action and put dangerous stresses on
the wheel.
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: When grinding with a new wheel be cer-
tain 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. 25).
5. Remove the tool from the work surface be-
fore turning the tool off. Allow the tool to
stop rotating before laying it down.
