CAUTION
After operation, always switch off the
tool and wait until the wheel has come
to a complete stop before putting the
tool down.
Visual inspection and
workout test on disc
1. Always make sure that the disc has no
cracks before use.
2. Always give workout test on the blade
as follows.
3. Always make sure the disc is firmly
fixed.
Work out time
Brand new disc
more than 3 min.
Before use on
current disc
more than 1 min.
Grinding operation [Fig.10]
ALWAYS hold the tool firmly with one
hand on grip and the other on the
support handle. Turn on the tool and
then apply the wheel or disc to the
workpiece.
In general, keep the edge of the wheel
or grinding disc at an angle of about
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
(Available as an accessory,
not included) [Fig.11]
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.
V. OPERATION

Be aware that this tool is always in an
operating condition, since it does not
have to be plugged into an electrical
outlet.

dangerous grinding disc breakage.
• ALWAYS replace grinding disc if tool
is dropped while grinding.
• NEVER bang or hit grinding disc.
• Avoid bouncing and snagging the
grinding disc, especially when
working corners, sharp edges etc.
This can cause loss of control and
kickback.
