  • Page 42: Engine Oil Level

    Engine oil level In 4-stroke engines, engine oil is used to lubricate the distribution elements, the bush- es and the thermal group. An insufficient quantity of oil can cause serious damage to the engine.In all four-stroke engines, a loss of efficiency in oil performance and certain consumption should be considered normal.
  • Page 43: Engine Oil Top-Up

    Engine oil top-up Any topping up with oil must be carried out after oil level check and by adding oil, but never exceeding the MAX level. The topping up of the level between MIN and MAX requires approx. 400 cm³ of oil. According to the instructions in the scheduled maintenance tables, engine oil level should be checked and topped up, if necessary, at an Authorised Piaggio Service Centre.
  • Page 44 WARNING RUNNING THE ENGINE WITH INSUFFICIENT LUBRICATION OR WITH INADE- QUATE LUBRICANTS ACCELERATES THE WEAR AND TEAR OF THE MOVING PARTS AND CAN CAUSE IRREVERSIBLE DAMAGE.

  • Page 55: Long Periods Of Inactivity

    Long periods of inactivity (03_19) Battery performance will decrease if the vehicle is not used for a long time. This is the result of the natural phenomenon of battery discharging, and may be due to residual absorption by vehicle components with constant power consumption. Poor battery performance may also be due to environmental conditions and the cleanness of the poles.
