Electrical system
- Refit the battery cover
Make sure that the terminals are connected correctly. When a new battery is installed, the correct time
and date must be reset on the digital instrument panel («Clock» and «MODE button» section).
CAUTION
DO NOT REVERSE THE POLARITY: RISK OF SHORT CIRCUIT AND DAMAGE TO THE ELEC-
TRICAL SYSTEM.
The electrolyte level, which should be checked regularly, must always be at the maximum level. To top
it up to this level, use only distilled water. Should it become necessary to top up the battery with water
too frequently, check the scooter's electrical system because the battery is being overloaded, causing
it to lose power quickly.
NEVER DISCONNECT THE BATTERY CABLES WHILE THE ENGINE IS RUNNING; THIS CAN
CAUSE PERMANENT DAMAGE TO THE VEHICLE ELECTRONIC CONTROL UNIT.
CAUTION
ELECTROLYTE CONTAINS SULPHURIC ACID: AVOID CONTACT WITH EYES, SKIN AND
CLOTHES. IN THE CASE OF ACCIDENTAL CONTACT, RINSE WITH ABUNDANT OF WATER AND
CONSULT A DOCTOR.
WARNING
SPENT BATTERIES ARE HARMFUL FOR THE ENVIRONMENT. COLLECTION AND DISPOSAL
SHOULD BE CARRIED OUT IN COMPLIANCE WITH CURRENT REGULATIONS.
