§THROTTLE VALVE HANDLE CLEARANCE ADJUSTMENT  § 
  Correct clearance allows throttle vale handle to rotate 
2~6mm. 
  Loosen the lock nut first, then turn the adjust nut to 
adjust.    Tighten the lock nut securely when finished. 
§INSPECTION AND MAINTENANCE OF BATTERY  § 
  The motorcycle is equipped with a maintenance-free type battery, so it is unnecessary to check and 
add electrolyte. Have your motorcycle checked by SYM Authorized Dealer should any abnormality is 
found. 
﹙Cleaning of battery terminals﹚ 
  Remove the battery terminals and clean if there are 
dirt and corrosion on them. 
  Battery removal procedures are as follows: 
Turn ignition switch key to the “OFF” position, then 
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, and 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. 
  The motorcycle is equipped with a maintenance-free type battery, so it is unnecessary to check and 
add electrolyte. Have your motorcycle checked by SYM Authorized Dealer should any abnormality is 
found. 
  CAUTION:   
  This is a closed type battery. Never remove the caps. 
  In order to prevent electric leakage and self-discharge when the battery sits idle for long periods. 
Remove battery from motorcycle; store it in well-ventilated and dimly lighted place after the battery 
has been fully charged. Disconnect battery’s negative cable if the battery is still kept on the 
motorcycle. 
  If the battery needs to be replaced, replace with a same closed-type battery (Maintenance-Free). 
Check Items: 
1. Check throttle valve cable to see if it can be moved 
smoothly from a closed position to a wide open position. 
2. Rotate steering handle from side to side to check if the 
throttle valve cable is interfered.   
3. Check to see if the throttle valve cable is obstructed by 
other cables preventing it from being operated smoothly.
