9. CHECKS & ADJUSTMENTS ON THE MACHINE AND BLADE
REPLACEMENT
9.1 Belt adjustment:
The V-belts placed on the machine are loosened over time. Also the belt adjustment is
necessary as it will be misadjusted after the belt replacements. If the belt is loose, it causes
noise during the running of the machine and shortens the life time of the belt. The machine
fails to cut if the belt is too loose. However, it may cause the roller bearings on the motor
and body to warm up if the belt is set very tightly.
The tightness of the belt should be
adjusted from the motor adjustment bolt, so that the distance between the two sides of the
belt should be 9 cm when it is pressed at the middle of both of the pulley centers.
