OPERATING THE BENCH GRINDER
USING THE WHEEL DRESSER (Fig. J)
The Wheel Dresser is to be used on the
grinding wheels. It will remove buildup up of
material on the grinding wheel, remove
imperfections and make the corners of the
grinding wheel square. See Figure J.
DO NOT use the Wheel Dresser on Wire
Wheels (not included) if they are installed on
the grinder.
1. Adjust tool rest (A) until it is in the flat
horizontal position as shown and 1/16” away
from the grinding wheel.
2. Turn “ON” the Bench Grinder. Let the
grinding wheel come up to a steady speed for
one minute.
3. After the grinding wheel has gotten to a
steady speed, place the Wheel Dresser head
(B) flat on the Tool Rest.
4. Firmly hold on to the handle of the Wheel
Dresser.
5. Move the Wheel Dresser forward until it
makes light contact with the grinding wheel
(C). After contact has been made, slide the
Wheel Dresser side to side across the Tool
Rest to dress the grinding wheel until the
edges of the grinding wheel are square and
the surface is clean.
6. After the dressing the grinding wheel, turn
“OFF” the Bench Grinder and let the grinding
wheel come to a complete stop. Allow the
grinding wheel to cool down for a period of 10
minutes before use.
7. Inspect the grinding wheel for any
irregularities that still need to be dressed,
or for and damage. If there is damage to the
wheel (cracks, major chips missing), replace
the wheel immediately.
8. The grinding wheel may now be slightly
smaller in diameter after dressing. Re-adjust
the tool rests and spark arrestors to maintain
a 1/16” clearance to the grinding wheel.
CHANGING THE GRINDING WHEEL
(Fig. K)
Due to normal wear, both wheels will need to
be replaced occasionally.
1. Turn the power switch OFF and unplug the
power cord from its power source.
2. Rotate the eyeshield up to access the tool
rest.
3. Loosen the tool rest knob and rotate the
tool rest away from the grinding wheel.
4. Remove the Wheel Cover (B) by
unscrewing the fasteners that hold it in place.
5. Lightly push a wood wedge between the
grinding wheel and the guard to keep the
shaft from turning. Then use a cresent wrench
to remove the arbor hex nut.
6. NOTE: The left hand arbor hex nut (E) 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.
