The 500 displa and related electrical Kit do not require special maintenance from
the user.
It is maintenance free for the final user except periodical cleaning from mud or dust.

Batter of the s stem should be charged once the displa show that it is at lower level
or when the s stem shut off because out of current.
Charge periodicall (at least ever 2 weeks) the batter .
Keep the batter at least 50% charged when the bike will be left for long time
not used. Batteries that will remain not charged at the lowest level for long time
ma loose performaces or even die.
Use a proper batter charger to charge the batter . For a 36V lithium batter a charger
with following specifications is required:
- Max 42V output charging tension
- Min 2A max 4A output charging current.
- 100/240Vac input voltage.
- Costant Current/Costant Voltage functioning s stem (specific for Lithium
batteries). Plug the charger to a Vac socket compliant with the voltage and
morpholog of the charger itself to charge the batter .
Use a matching connector to connect charger to batter . Do not tr to modif a not
matching one to connect the batter .
If the user warn a problem during the ride of the bike, it is important to bring the
