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
necessary 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
fluid. 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
Komatsu Dealer, who will supply you with exhaustive and precise information.
