paragraph 7.8. “Disassembling the motor
guard”.
2. Raise the machine to an incline of

Figure 8.5-2
5. Back off the 2 outer nuts b using a 13-mm
wrench.
6. Use a belt tension gauge.
7. Turn the 2 inner adjusting nuts c using a 13-
mm wrench, until the instrument measures a
tension of 35 Kg.
If a belt tension gauge is not available,
the belt tension is correct when:
• it yields by 0.5 – 1 cm when pressed
vertically with the hand.
• it does not slip when the tread-belt is
blocked at 1.0 Km/h.
After completing this procedure lock
down the fixing nut according to the
torque values described in paragraph
7.9. “Disassembling the tread-belt
motor” and check the belt tension again.
