8.7 TENSIONING THE TRANSMISSION BELTS
Before commissioning of the appliance,
always check the direction of rotation of the
motors without load. To do this, remove the
V-belts by rst unlocking the four screws in
the motor base (g. 8.10).
If the rotation is dierent from the desired
direction, disconnect the power supply and
invert the two power supply phases, thus
setting the correct direction of rotation. Put
the V-belts back and check that the pulleys
are aligned, as in g. 8.12.
V-belt tensioning method:
■ loosen screws 1-4 in the motor base;
■ using screw 5, adjust the tension of the
V-belts appropriately (see graphic g.
8.11);
■ tighten screws 1-4 blocking the motor
base.

To nd the proper tensioning of the belts, use the following formula:

When starting the devices for the rst time, check the
tensioning of the V-belts after 2-4 working hours. If ne-
cessary, correct as described
ATTENTION
All belt tensioning operations must be carried out with the appliance switched o,
disconnected from the power supply.
