3.7.3 Side setting of the indented upper pulley
The pulley is to be set in such a way that the indented belt is
not crossed and the pulleys are in line. The setting thereof is
to be done as follows:
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Loosen the screws (1) of the pulley (2).
- Set the pulley (2) in such a way that the distance of 5 mm
is attained in accordance with the illustration.
- Tighten the screws (1).
3.7.4 Setting the tensioning roller
The tensioning roller of the indented belt of the top feeding
is mounted in a rotary way on the bedplate. The belt must be ten-
sioned as needed in such a way that there is ensured the correct
function of the transmission. Insufficient tension can cause
skipping of the teeth, on the contrary, excessive tensioning
enormously loads the mounting of the top shaft. The setting thereof
is to be done as follows:
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Loosen the screw (1) securing the lever of the tensioning roller
(2).
- Tension the belt as needed (theoretically, in applying the force
of 10 N in the middle of the belt with the deflection of 4 mm).
- Tighten the screw (1).
