3. Drive belt
a) In order to replace the drive belt, loosen four bolts (1- 4). Next, loosen the tension bolt (5) to
allow the motor to pivot towards the belt pulley. Take off the belt. Replace with a new belt being
careful to make sure that the belt is as close as possible to the main shaft assembly to allow it to
fit correctly onto the small drive pulley. Tighten the tension bolt (5) and then the four mounting
bolts (1-4). Make sure that the tension on the belt is sufficient to allow 1cm
b) The direction arrows on the drive belt have no role to play because the rotation of 150 rpm for
the main shaft is very low. Direction arrows can be ignored.
(Drive belt, Art.Nr. 1987009WK1A)
c) Noises coming from the belt do not affect the results on the machine. Do not use grease or oils
to lubricate otherwise the loss of friction on the pulley could alter the rotational speed of the main
shaft.
