Operation with abrasive cut-off / diamond
wheel (optional accessory)
Fig.10
The direction for mounting the lock nut and the inner
flange varies by wheel thickness. Refer to the table
below.

WARNING:
When using an abrasive cut-off / diamond wheel,
•
be sure to use only the special wheel guard
designed for use with cut-off wheels. (In European
countries, when using a diamond wheel, the
ordinary guard can be used.)
NEVER use cut-off wheel for side grinding.
•
Do not "jam" the wheel or apply excessive
•
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of
kickback, wheel breakage and overheating of the
motor may occur.

Do not start the cutting operation in the workpiece.
•
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the
workpiece surface. The wheel may bind, walk up
or kickback if the power tool is started in the
workpiece.
During cutting operations, never change the angle
•
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
A diamond wheel shall be operated perpendicular
•
to the material being cut.
