ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both A
and B direction.

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.
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

Remove the battery cartridge from the tool and place it
upside down allowing easy access to spindle. Mount the
inner flange and abrasive cut-off / diamond wheel onto
the spindle. Tighten the lock nut securely with supplied
wrench. The direction for mounting the lock nut and the
inner flange varies by wheel thickness.
Refer to the table below.

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.
