16. SPIN AND BRAKE DEVICE

16.1 Replacing and adjusting the belt

- Remove the weight tray;
- Unscrew the fixing screws of the side closing panel on the motor compartment;
- Unscrew the nut and locknut used to tighten the belt (A1, A2, Fig. 13);
- Loosen the three motor fixing screws (B, Fig. 13) on the motor support;
- Disassemble the belt (C, Fig. 13) and replace it with the new one.
- Tighten the belt by screwing the nut A1. The belt is correctly tightened when the oscillation frequency of one of the two branches is equal to
200Hz (tollerance +5/-10Hz). The tension must be measured using the specific instrument. Only in the case that suitable equipment is not available,
approximate tension can be performed so that when pressing your finger on the middle of one of the two branches, the belt flexion is approx. 10mm.
Warning: excessive belt tension can cause, with machine use, damage to the motor bearings and/or motor shaft failure. a too slow belt can cause a
decrease in performance, excessive noise at the beginning and when braking and rapid wear to the belt itself.
- Block the locknut A2;
- block the motor fixing screws (B, Fig. 13).
