4-3 ADJUSTMENT AND REPLACEMENT OF
THE SAW ARBOR BELTS
A loosening of the machine's transmission belts will inevitably take place after
extended use and cause reduced efficiency. In order to minimize wearing of the
belts and the loss of machine's power, the belts should be re-tightened by increasing
an appropriate distance between the saw arbor pulley and the motor pulley.
The distance between the saw arbor pulley and the motor pulley is adjusted by a
threaded rod (using an adjustable spanner or 26mm open-end wrench as tools).
Before adjusting or changing the belts, loosen the fixed nut by turning in a clockwise
direction. The threaded rod can then be turned until the desired position is reached
(loosen by turning in a clockwise direction, tighten in a counter-clockwise direction).
After finish the adjustment, the fixed nut must be tightened again by turning in a
counter-clockwise.
New belts should be re-tightened after the first 4 working hours. After 8 working
hours they should be re-tightened again. Thereafter, the belts should be inspected and
adjusted after every 200 working hours. If the belts show the signs of wear, they
should be replaced by new belts of the same brand and from the same production
batch. Old and new belts should never be used together.
For the specifications of the saw arbor belts used by this machine, please consult the
"SPECIFICATIONS" chapter at the front of this manual.
