PRECAUTIONS TO BE TAKEN IN THE COLD SEASON

3.11 PRECAUTIONS TO BE TAKEN IN THE COLD SEASON
During the cold season or in areas where the temperature is particularly low, especially during the night, it is nec-
essary to take some countermeasures meant to limit the damage deriving from low temperatures.

3.11.1 FUEL AND LUBRICANTS

1 - Change the fuel and use the winter fuel ASTM D975 N. 1.
2 - Change the engine oil with an oil with suitable viscosity.
For the relevant specifications, see "4.3 FUEL, COOLANT AND LUBRICANTS".

3.11.2 COOLANT

DANGER
The coolant containing antifreeze is flammable; do not smoke and do not use naked flames during the
checks and when preparing the mixture.
Do not use methanol-, ethanol- or propanol-based antifreezes.
1 - If no permanent antifreeze is available, use an antifreeze mixture made of ethylene glycol added to anticorro-
sion and antifoam products.
Use this mixture only during the winter and when changing the coolant (in autumn or spring) wash the cooling
circuit (see "4.7.1 WHEN REQUIRED").
2 - When it is necessary to calculate the antifreeze-water ratio, refer to the lowest temperature measured in the
past and consider a temperature 10° C lower than that. (See "4.2.1.2 COOLANT").
3 - Do not use plugging additives, either alone or added to the antifreeze, to eliminate leakages.
4 - Do not mix antifreezes of different brands.
5 - If a permanent antifreeze is used during the year, it is not necessary to change it and to wash the circuit.
6 - The required standards for the permanent antifreeze are SAE-J1034 and FEDERAL STANDARD O-A-548D.
In case of doubt regarding the compliance of the antifreeze used with the standards, contact the manufacturer
and ask for precise information.

3.11.3 BATTERY

DANGER
To avoid explosions due to the presence of gas, do not provoke sparks and do not use naked flames
near the battery.
The battery electrolyte is dangerous. If it comes in contact with the eyes or the skin, immediately rinse
with plenty of water and consult a doctor without delay.
