8.4 Monthly maintenance and checks
8.4.1 Control of circuits and electrical components
Check the condition and fastening of the battery cables: the sheaths of the electric cables must be in good condition and
the terminals must be well tightened, not corroded and covered with insulating grease.
Check that all bulbs and warning lights are switched on correctly.
8.4.1 Control and adjustment of the rear derailleur
Adjusting the lower and upper limit switches of the rear derailleur: Turn the two screws (Ref. V-Z - Figure 19) so that the
chain does not come out. The chain displacement device must be in line with both the larger gear and the smaller one (
Rif. Figure 20)
To prevent damage to the gearbox, it is recommended not to
exert too much pressure on the pedals while shifting gears. So
avoid shifting when exerting effort or driving on slopes.
Adjust the tension of the cable by acting on the appropriate
control to ensure the immediate response of the rear derailleur
to the control of the handle on the handlebar. (Ref. Figure 21)
