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 dam
aged, or which is out of
balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.

Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire cup brush onto spindle and tighten with
supplied wrench. When using brush, avoid applying too
much pressure which causes over bending of wires,
leading to premature breakage.
Operation with wire wheel brush
(optional accessory)
CAUTION:
Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
Do not use wire wheel brush that is damaged, or
which is out of balance. Use of damaged wire
wheel brush could increase potential for injury from
contact with broken wires.
ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard. Wheel
can shatter during use and guard helps to reduce
chances of personal injury.
