7. Re-tighten the disc table adjustment handle.

V-Belt
Should the rotation of the sanding belt or disc slow down or stall,
the cause may be that the V-belt is slipping on the two pulleys.
This may be because the motor or frame have become loose from
the base, or that the V-belt has stretched out due to the machine
being used. In either case, re-adjustment of the V-belt is needed.
1. To gain access to the V-Belt (Part #8), the Belt Cover (#39)
must be removed, by unscrewing the two hex head Screws
(#112).
2. On the cabinet top, under the sanding belt frame, there are two
hex head Bolts and Nuts (#18, 19) that extend up from the
cabinet surface. These connect to the motor frame and will adjust
the tension of the V-Belt by pivoting the motor.
Loosen the locking nuts and then rotate the bolts so that the
motor frame is moved to put more, or less, tension on the V-Belt.
3. Tension, or the deflection of the V-belt should be about 6mm to
9mm when moderate pressure is applied onto the belt with your
finger.
4. Once the proper belt tension is achieved, tighten the hex head
bolts to secure the motor frame in its new position.
5. Re-install the safety belt cover over the V-belt, that was
removed in step 1 above.
