GENERAL INFORMATION
This solution is also suitable during the warm season, as it is less likely to evaporate and will reduce the need for
frequent top-ups.
In addition, less water evaporation means fewer mineral salt deposits in the radiator, which helps preserve the efficiency
of the cooling system.
When the temperature drops below 0"C check the cooling system frequently and add more antifreeze (up to 60%
maximum) to the solution, if needed.
Use distilled water in the coolant mixture. Tap water will damage the engine.
Refer to the chart given below and add the indicated quantity of antifreeze to the water to obtain a solution with the
desired freezing point:
Freezing point °C (°F)
-20° (-4 °F)
-30° (-22 °F)
-40° (-40 °F)
NOTE Coolants have different specifications. The protection degree is written on the label.
WARNING
Use nitrite-free and anticorrosion coolant only to ensure protection at least at -35°C (-31 °F).
DRIVE CHAIN
Check drive chain operation, wear, slack and lubrication at regular intervals.
The vehicle is equipped with an endless chain with master link.
WARNING
If too slack, the chain can come off the front or rear sprocket thus resulting in serious accidents and
damage to the vehicle, with consequent serious personal injury or death.
Do not use the vehicle if the chain slack has not been correctly adjusted.
To check the chain, hold it where it turns on the rear sprocket and pull it as if to separate it from the
sprocket itself.
If you can move it more than 3 mm (0.125 in) from the front sprocket, it is worn; replace the chain, and
the front and rear sprocket.
DANGER
Improper maintenance can cause premature wear of the chain and result in damage to both the front
and rear sprocket.
Perform chain maintenance operations more frequently if the vehicle is used on dusty roads or in
muddy areas.
TYRES
WARNING
An over-inflated tyre results in a hard, uncomfortable and less secure ride.
Over inflation also affects grip, especially on curves and wet surfaces.
An under-inflated tyre (insufficient pressure) can slip on the wheel rim, resulting in loss of control.
Under inflation also affects grip and handling, as well as braking efficiency.
Tyre changing and repair, and wheel servicing and balancing are delicate operations. They should be
carried out using adequate tools and are best left to experienced mechanics.
When new, tyres can have a thin slippery protective coating. Drive carefully for the first few kilometres
(miles).
Never use rubber treatment products on the tyres.
In particular, do not allow the tyre to come in contact with liquid fuel, which rapidly deteriorates the
tyre rubber.
In case of contact with oil or fuel, do not clean but change the tyres.
DANGER
Some of the factory-assembled tyres of this vehicle are provided with wear indicators.
There are various types of wear indicators.
For more information on how to check the wear, contact your Dealer.
Check wear visually and have the tyres replaced when they are worn.
If a tyre deflates during a ride, do not attempt to continue the trip.
Avoid sudden braking or steering manoeuvres, and do not decelerate abruptly.
Slowly decelerate and move to the edge of the road braking with the engine until you come to a
standstill.
Failure to observe these instructions can result in accidents, with the risk of serious personal injury or
death.
Never use tube tyres on tubeless tyre rims, or vice versa.
