3.5 USING THE MACHINE IN THE COLD SEASON
3.5.1 PRECAUTIONS TO BE TAKEN WHEN USING THE MACHINE 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.
3.5.1.1 FUEL AND LUBRICANTS
Change fuel and oil with low viscosity products for all components. For details on the required viscosity, see "4.2
MAINTENANCE NOTES".
3.5.1.2 COOLANT
WARNING
q
Antifreeze is toxic. Avoid any contact with the eyes or the skin. In case of contact with the eyes or the
skin, wash with plenty of running water and consult a doctor without delay.
q
To replace the coolant or carry out operations with coolant containing antifreeze fluid drained during ra-
diator repair, please contact your Komatsu Distributor or a company specialised in this kind of opera-
tion.
Antifreeze fluid is toxic. Do not let it drain for the drainage channels or spray it on the ground.
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 Komatsu original coolant antifreeze (AF-NAC) to dilute according to the minimum atmospheric tem-
perature indicated in the table in section "4.4.1 COOLANT".
2 - Do not mix different brands of antifreeze.
3 - The use of permanent antifreeze coolant only requires the level check and scheduled replacement. 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 Distributor, who will supply you with exhaustive and precise information.
