Metal Grinding
The rated speed of the ac-
cessory must be at least
equal to the maximum speed marked on the
power tool. Accessories running faster than
their rated speed can break and fly apart .
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 . 21) .
Fig. 21
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 .

Operation
Metal Cutting
ting. Cutting with a Type B (27) wheel guard
may not provide the operator sufficient protec-
tion 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 .
4 . Do not exert side pressure onto the cutting
disc . Do not tilt or oscillate the tool as wheel
may burst, (Fig . 22) .

5 . Remove the tool from the work surface be-
fore turning the tool off . Allow the tool to
stop rotating before laying it down .
Always use Type A (1A/41)
