PRECAUTIONS TO BE TAKEN IN THE COLD SEASON
3.10 PRECAUTIONS TO BE TAKEN IN THE COLD SEASON
3.10.1 FUEL AND LUBRICANTS
3.10.2 COOLANT
3.10.3 BATTERY
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.
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”.
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 - Use only permanent, ethylene glycol-based antifreeze, with corrosion inhibitors and antifoam products.
2 - The antifreeze-water ratio must be 1:1 (50% antifreeze and 50% water).
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 - The use of permanent antifreeze requires only the check of the level and the periodical change of the fluid. It
is not necessary to wash the cooling 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.
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.
•
To prevent the fluid from freezing, add distilled water in the morning, before starting work.
