CHARLY OPERATING INSTRUCTIONS

15.3. Toothed belt tension

WARNING
The useful life of the toothed belt essentially depends on the
appropriate tension.
Check the toothed belt tension every 500 km (300 miles) run.
The toothed belt causes a risk of personal injury if CHARLY is test
run when the covering is not secured in place.
Test runs without covering are prohibited.
2
Check the tension of the toothed belt every 500 km (300 miles) run or earlier in case of
heavier use. Readjust the tension if necessary. If this is not done, the drive cannot work
without loss, and it is exposed to greater wear and tear.
To tighten the belt, first remove seat support and scooter body. The belt must allow a
deflection of approximately A = 4 mm (0.16 in) when applying a force (F) of 14...15 N at
the centre as indicated by the point shown in the photograph. If this value is not reached,
loosen the motor fastening screws (1) and turn both nuts (2) to readjust the belt tension to
the correct value. Then, reinstall all parts and tighten all appropriate screws.
