3.10 PRECAUTIONS TO BE TAKEN IN THE COLD SEASON AND IN
COLD PLACES
During the cold season or in areas where temperatures are particularly low, especially during the night, it is neces-
sary to take some countermeasures meant to limit any damage deriving from low temperatures.
3.10.1 FUEL AND LUBRICANTS
1 - Change the fuel and use winter fuel type 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».
3.10.2 ENGINE COOLANT
• Use only permanent, ethylene glycol-based coolant, with corrosion inhibitor for protection up to -36°C.
The coolant density must be checked every year before the cold season and the coolant must be changed every
2 years.
3.10.3 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.
• To prevent the fluid from freezing, add distilled water in the morning, before starting work.
1 - When the ambient temperature decreases, the battery capacity decreases accordingly and, if the battery
charge is low, the electrolyte may freeze.
Keep the battery completely charged and insulate it to protect it from low temperatures, so that the machine
can be started without problems in the morning.
2 - Measure the specific weight of the electrolyte and check the battery charge percentage, using the following ta-
ble:
CHARGE
PERCENTAGE
ELECTROLYTE DENSITY
20°C 0°C -10°C -20°C
100% 1.28 1.29 1.30 1.31
90% 1.26 1.27 1.28 1.29
80% 1.24 1.25 1.26 1.27
75% 1.23 1.24 1.25 1.26
