check if the throttle valve cable is interfered.

INSPECTION AND MAINTENANCE OF BATTERY
This scooter is equipped with a maintenance-free type battery, so it is unnecessary to check and add
electrolyte. Have your scooter checked by SYM Authorized Dealer or Franchised Dealer should any
abnormality is found.
Remove the battery terminals and clean if there
are dirt and corrosion on them.
Battery removal procedures are as follows:
Turn ignition switch “OFF,” and remove negative
cable screw firstly and disconnect the negative
cable. Then, remove positive cable screw and
positive cable.
CAUTION:
Clean the battery posts with warm water if the posts are eroded and have some white powders on
them.
If there is an obvious erosion on the terminals, disconnect the cables, then clean the erosion off with
a steel brush or a piece of sandpaper.
Install battery cable after cleaning and apply a thin coat of grease on the terminals.
Install battery in reverse order of removal.
Do not disconnect the battery cables from the battery when the engine is running to prevent
any electronic parts from being damaged.
