3.10 PRECAUTIONS TO BE TAKEN IN THE COLD SEASON
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 COOLANT
WARNING
q
The coolant containing antifreeze is flammable; do not smoke and do not use naked flames during the
checks and when preparing the mixture.
1 - Use only red permanent antifreeze suitable for aluminium radiators.
Pure red antifreeze must be diluted with water (50%) to ensure protection down to -36°C.
2 - Do not mix different brands of antifreeze.
3 - The use of red permanent antifreeze requires only the check of the level and the periodical change of the flu-
id. It is not necessary to wash the cooling circuit.
4 - In case of doubt regarding the applicable standards for the use of permanent antifreeze, contact your Komat-
su Dealer, who will supply you with exhaustive and precise information.
