BASIC OPERATION
AUTOMATIC TRANSMISSION
For easy and comfortable riding, your new vehicle has an automatic transmission with a
centrifugal clutch. This system is designed to provide optimal fuel consumption and acceleration
by adjusting the transmission ratio in relation to torque demands and engine speed. If you need
to stop on a hill gradient (traffic lights, tailbacks etc.) restrain the vehicle with the brakes alone
(engine should be idling). Using the engine to hold the vehicle can Cause the clutch to overheat.
Prolonged slipping of the centrifugal clutch causes overheating. Apart from the example above,
the clutch will tend to slip when tackling very steep gradients with a heavily laden vehicle or
when starting up on gradients greater than 25%.
1. Limit the duration of extreme conditions such as the above.
2. Allow the engine to idle for a few minutes to give the clutch time to cool.
WARNING
The life of your motor scooter's CVT transmission will be greatly extended if you avoid
situations in which the motor scooter will be overloaded, or started on very steep hills.
DEEP WATER
Do not drive on flooded roads or standing water such as puddles.
Water entering the engine and being ingested by the air intake can cause damage to electrical
components, wiring, engine or transmission and is not covered by the Lambretta Limited
Warranty.
