Operation with abrasive cut-off /
diamond wheel
Optional accessory
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.
WARNING:
NEVER use cut-off wheel for side
grinding.
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.
