Preliminary Adjustments (continued)
2.
Clamp Handle Rotary Cam
(Figure 4)
The clamp must hold two belts securely to the
table. Check it with two pieces of the type of belt
that you will be grinding, making sure that it
applies an equal amount of pressure to each
piece (the gap should be equal on both ends),
and that both belts are held securely in place.
If adjustment is needed, use a 1/8
″
hex key to
loosen the two clamp handle setscrews and
rotate the brass cam bearings on each end to
increase or decrease the tension on the clamp
handle. Retighten the setscrews securely after
adjusting.

Zero Point Adjustment
(Figure 5)
Turn the hand crank until the end of the table is
directly under the grinding drum. Look under the
aluminum guard and check the gap between the
abrasive surface of the grinding drum and the
table. The edge of the table should just barely
touch the abrasive drum, and the two surfaces
should be perfectly parallel to each other.
If adjustment is needed, remove the 7/16
″
nuts
holding the aluminum guard, and lift off the
guard. Then loosen the 7/16
″
jam-nuts on the
grinding drum setscrews, and back out the
setscrews slightly using a 1/8
″
hex key, until the
drum nuts can be turned. Turn the large drum
nuts counterclockwise to lower the drum or
clockwise to raise it. Once the drum height is
properly adjusted, tighten the setscrews and
jam-nuts, and reinstall the guard.
