N.B.
FAILURE TO OBSERVE THESE INSTRUCTIONS MAY RESULT IN WRONG VACUUM INSIDE THE
FILTER HOUSING, WHICH IN TURN MAY PRODUCE VARIATIONS IN CARBURETION.
CAUTION
IF THE VEHICLE IS USED ON DUSTY ROADS IT IS NECESSARY TO CARRY OUT MAINTENANCE
CHECKS OF THE AIR FILTER MORE OFTEN TO AVOID DAMAGING THE ENGINE.
Engine oil
In four stroke engines, the engine oil is used to lubricate the timing elements, the bench bearings and
the thermal group. An insufficient quantity of oil can cause serious damage to the engine.
In all four stroke engines, the deterioration of the oil characteristics, or a certain consumption should
be considered normal, especially if during the run-in period. Consumption levels in particular can be
influenced by the conditions of use (e.g.: oil consumption increases when driving at "full throttle".
Replacement
Change oil and replace filter as indicated in the
scheduled maintenance table. The engine must be
emptied by draining off the oil through the drainage
plug of the mesh pre-filter, flywheel side; further-
more to facilitate oil drainage, loosen or remove
the cap/dipstick. Once all the oil has drained
through the drainage hole, unscrew the oil car-
tridge filter and remove it.
