PROLONGED INACTIVITY
A few simple operations should be performed to keep the vehicle in good condition
whenever it is to remain inactive for a long period (e.g. during the winter):
Thoroughly clean the vehicle.
Reduce the tyre pressures by approximately 30 percent, and if possible raise the
tyres off the ground.
Remove the spark plug and pour a few drops of engine oil into the spark plug hole.
Make the engine turn a few times by operating the kick-start (where available) and
then replace the spark plug.
Cover the unpainted parts, excepting the brakes and the rubber parts, with a film
of oil or spray silicone.
Remove the battery and keep it in a dry place. Charge the battery every 15 days.
AFTER PROLONGED INACTIVITY
Reinstall the battery.
Restore the tyre inflating pressures.
Check the tightening of all the screws having an important mechanical function.
Note:
Periodically check the tightening of the screws.
Start the vehicle for the first time by means of the kick-start.
Protect the vehicle with a dust cover.
Drain the carburetor float chamber by
loosening screw A. The fuel drained from
the chamber through a suitable pipe must
be collected in a container and poured
into the fuel tank. Do not dispose of the
fuel in the environment.
Retighten the screw.
