The direction for mounting the lock nut and the inner
flange varies by wheel thickness. Refer to the table
below.
Abrasive cut-off wheel
Thickness: Less than 4 mm (5/32")
22.23 mm (7/8")
1. Lock nut

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.
