- The finger conditioning rotor and ribbed rollers are
driven by two sets of V-belts.
- It is critical that both sets of drive belts be checked
for correct tension after the first hour of operation.
- To do this, lift hood (2).
- Rotate nut (3) clockwise to tighten the belts.
- Belt tension is correct when each belt can be
deflected maximum 10 mm (1/2") when applying
pressure to the back of the belts at mid distance
between the pulleys.
Belts must not be changed individu-
ally. Only replace belts as a complete
set.
Loosen the belts when not using the
machine for long periods.
