Operation with abrasive cut-off /
diamond wheel
Optional accessory
WARNING:
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.
WARNING:
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.
WARNING:
During cutting operations, never
change the angle of the wheel. Placing side pres-
sure on the cut-off wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING:
A diamond wheel shall be oper-
ated perpendicular to the material being cut.

Operation with wire cup brush
Optional accessory
CAUTION:
Check operation of brush by run-
ning tool with no load, insuring that no one is in
front of or in line with brush.
NOTICE:
Avoid applying too much pressure
which causes over bending of wires when using
the wire cup brush. It may lead to premature
breakage.
