ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Do not touch the metal
parts. 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
ﾟ
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 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.
Operation with wire cup brush
(optional accessory)
CAUTION:
•
Check operation of brush by running tool with no
load, insuring that no one is in front of or in line with
brush.
•
Do not use brush that is damaged, or which is out of
balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.
