Figure 8.4-1
Carry out the procedures described in paragraphs
7.8. “Disassembling the motor guard” and 7.10.
“Disassembling the front plate”.
1. Remove the dust guard.
2. Back off the 4 nuts a (2 are concealed by the
motor in the figure at left) fixing the belt
motor to the machine frame, using a 13-mm
screw and holding the screw underneath in
place with a 6-mm Allen T-wrench.
Figure 8.4-2
3. Back off the 2 outer nuts b using a 13-mm
wrench.
4. Use a tension gauge for belts.
5. Turn the 2 inner adjusting nuts c using a 13-
mm wrench until the instrument measures a
tension of 35 kg.
If a tension gauge is not available, the
tension of the motor belt 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 0.8 km/h.
After completing this procedure, lock
down the fixing nuts and check the belt
tension again.
