CHANGING THE GRINDING WHEEL

Refer to Figure 6.
Due to normal wear, both wheels will need to be replaced
occasionally.
• Turn the power switch OFF and unplug the power cord
from its power source.
• Rotate the eyeshield up to access the tool rest.
• Loosen the tool rest knob and rotate the tool rest away
from the grinding wheel.
• Turn quick release knob (A) counter-clockwise to remove
knob from guard completely.
• Rotate the quick change wheel cover (B) back about
to release it from the inner wheel guard (C).
• Place a crescent wrench (not included) on the arbor hex
nut (D). Place the slot of the special wrench (included
with your grinder) onto the flats of the arbor shaft (E).

NOTE: The left hand arbor hex nut is left hand threaded
and is loosened by rotating it clockwise. The right hand
arbor hex nut is right hand threaded and is loosened by
rotating it counter-clockwise.
• Remove the outer wheel flange (F) and then the abrasive
wheel (G) from the arbor shaft.
CAUTION:
The new abrasive wheel to be put onto the
grinder must have a higher R.P.M. rating than the grinder
(3450 R.P.M.). The new abrasive wheel must have the cor-
rect outer wheel diameter and bore diameter as original
wheels. The label on the side of the abrasive wheel must
stay on. DO NOT remove this label.

• Replace the abrasive wheel, outer wheel flange and
arbor hex nut.
NOTE: The left hand arbor hex nut is left hand threaded
and is tightened by rotating it counter-clockwise. The right
hand arbor hex nut is right hand threaded and is tightened
by rotating it clockwise.
CAUTION:
Do Not Over-Tighten the arbor hex nut as
this may damage the abrasive wheel and cause serious
injury to the operator.
WIRE WHEEL OR BUFFING WHEEL
Refer to Figure 7.
A wire wheel or buffing wheel (A) can be used with your
grinder. Depending on the thickness of the wheel, you will
need to add one or more spacers to allow the arbor hex
nut to tighten correctly. These spacers are identical to each
other. Figure 7 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, will go on
next to the arbor hex 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.
