Interface System; Suggestions On Engine Fuel; Transmission Oil; Cautions For Riding Scooter - Sym LV30/25/12W1-EU Série Manuel D'utilisation

12. E.C.U. CIRCUIT INTERFACE SYSTEM
● This hardware component consists of a 16-bit microcomputer that is its control center. It contains the
functional circuit interface of engine condition sensing and the driving actuator for the fuel injector, fuel
pump, ignition coil...and so on.

13. SUGGESTIONS ON ENGINE FUEL

 This scooter is designed to use UNLEADED gasoline of Octane No. 92(RON) or greater.
 If the scooter is operated in high attitude (where the atmosphere pressure is lower), it is suggested that the
air/fuel ratio should be re-adjusted to maximize the engine performance.

14. TRANSMISSION OIL

 Recommended Oil: Genuine〝SYMOIL〞GEAR OIL (SAE 85W-140 GL-5)
Use SAE85-90 when outside temperature is below 0℃.

15. CAUTIONS FOR RIDING SCOOTER

1. Raise the scooter with the main stand, and sit on the saddle.
Push the scooter forwarding to raise the main parking stand.
CAUTION:
 Never rotate the throttle valve handle arbitrarily to increase the engine RPM before driving off.
2. Get on the scooter from the left side, and sit on the saddle properly, keep your feet firmly on the
ground to prevent the scooter from falling.
CAUTION:
 Apply brake on the rear wheel before driving off.
3. Rotate the throttle valve handle slowly, and then the scooter will begin to move.
CAUTION:
 Rapidly rotate the throttle valve handle may cause the scooter moving forward suddenly and it is
very dangerous.
 Make sure the side parking stand is spring back completely before driving off.
【Do not use the brake suddenly and make a sharp turn】
 Rapid braking and sharp turning will cause slip and fall.
 Rapid braking or sharp turning will cause slipping, lateral slipping, or fall especially in rainy days when the
road is wet and slippery.
【Drive with extreme caution during rainy days】
 The brake distance in rain day or on wet road will longer than on a dry road. Therefore, slow down and
prepare to apply the brake earlier.
 The throttle valve handle should be released, and the brakes should be properly applied as it is needed
while reducing the speed when going down a slope.
