15º-30º to the workpiece surface.
When using a new grinding disc, do not
work the grinder in the B direction or it will
cut into the workpiece. Once the edge of
the grinding disc has been rounded off by
use, the grinding disc may be worked in
both A and B direction.
Using a cut-off disc guard
(EY9X213E) (Available as an
accessory, not included)
Make sure the side.
WARNING:
• When using an abrasive cut-off
disc, be sure to use only the cut-off
disc guard designed for this use
with cut-off disc.
• NEVER use cut-off disc for grinding.
• Do not jam the Disc or apply ex-
cessive pressure. Do not attempt
to make an excessive depth of cut.
Overstressing the cut-off disc in-
creases the loading and suscepti-
bility to twisting or binding of the
cut-off disc in the cut and the pos-
sibility of kickback, cut-off disc
breakage and overheating of the
motor may occur.
• Do not start when disc is in the
workpiece. To do so causes the
cut-off disc binding or kickback. Let
the cut-off disc reach full speed and
then carefully cut the workpiece.
• During cutting operations, never
change the angle of the disc. Plac-
ing side pressure on the cut-off
disc (as in grinding) will cause the
disc to crack and break, causing
serious personal injury.
CAUTION:
• To prevent excessive temperature
increase of the tool surface, do not
operate the tool continuously us-
ing two or more battery packs. The
tool needs cool-off time before
switching to another pack.
• Do not close up ventilation slots on
the sides of the body during operation.
Otherwise, the machine function is
adversely affected to cause a failure.
• Do NOT strain the tool (motor). This
may cause damage to the unit.
• Use the tool in such a way as to
prevent the air from the ventilation
slots from blowing directly onto
your skin. Otherwise, you may get
burned.
