Have your scooter checked, adjusted periodically by your SYM Authorized Dealer to maintain the scooter at the
optimum condition
Code: I ~ Inspection, cleaning, and adjustment R ~ Replacement
C ~ Cleaning (replaced if necessary) L ~ Lubrication
The above maintenance schedule is established by taking the monthly 1000 kilometers as a reference which ever
comes first.
Remarks:
1. Clean or replace the air cleaner element more often for pro-long engine life-span when the scooter
is operated on dusty roads or in the Heavily- polluted environment.
2. Maintenance should be performed more often if the scooter is frequently operated in high speed
and after the scooter has accumulated a higher mileage.
