GENERAL INFORMATION
COOLANT
DANGER
Coolant is toxic when ingested, contact with eyes or skin may cause irritation.
In the event of contact with skin or eyes, rinse repeatedly with abundant water and seek medical
advice. In the event of ingestion, induce vomiting, rinse mouth and throat with abundant water and
seek medical advice immediately.
DO NOT RELEASE COOLANT INTO THE ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
DANGER
Take care not to spill coolant onto hot engine parts. It may ignite and produce invisible flames. Wear
latex
Do not ride when coolant is below the minimum level.
Coolant mixture is a 50% solution of water and antifreeze. This is the ideal solution for most operating temperatures and
provides good corrosion protection.
This solution is also suited to warm weather, as it is less prone to evaporative loss and will reduce the need for top-ups.
In addition, less water evaporation means fewer minerals salts depositing in the radiator, which helps preserve the
efficiency of the cooling system.
When the temperature drops below 32°F (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 water with the quantity of antifreeze to obtain a solution with the desired freezing
point:
Freezing point °F (°C)
-4°F (-20°C).
-22°F (-30°C).
-40°F (-40°C).
NOTE Coolants have different specifications. The protection degree is written on the label.
WARNING
Use only nitrite-free antifreeze and corrosion inhibitors with a freezing point of -35°C
(-31°F) as a minimum.
DRIVE CHAIN
Check drive chain operation, wear, slack and lubrication at regular intervals.
The vehicle is equipped with an endless chain with a joint link.
WARNING
If too slack, the chain can come off the front or rear sprockets and lead to serious accident 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, take it with your hand where it turns on the rear sprocket and pull it as to separate
it from the sprocket itself.
If you can move the chain apart of the front sprocket for more than 3 mm (0.125 in), change chain,
front and rear sprocket.
DANGER
If not properly maintained, the chain can wear out prematurely and lead to damage of both front and
rear sprockets.
Perform chain maintenance operations more frequently if the vehicle is used on rainy or dusty areas.
