A wire wheel or buffing wheel (A) can be used with your
grinder. Depending on the thickness of the wheel, you
wiii need to add one or more spacers to allow the arbor
hex nut to tighten correctly. These spacers are identical
to each other. Figure P shows the correct placement of
the spacers (B) and (C).
Note: One spacer (B) should always go onto the arbor
shaft first. The second spacer (C), if needed, wiii go on
next to the arbor hext nut (D) as shown. Always use the
wheel flanges (E) that came with the grinder for both
wire wheel and buffing wheels. See section CHANGING
THE GRiNDiNG WHEEL for correct procedure of
changing wheels.
