14. COLD WEATHER OPERATION 14.1 PRECAUTIONS FOR LOW TEMPERATURE If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as follows. 14.1.1 FUEL AND LUBRICANTS Change to fuel and oil with low viscosity for all components. For details of the specified viscosity, see “20. RECOMMENDED FUEL, COOLANT, AND LUBRICANT”. 14.1.2 COOLANT WARNING Antifreeze is toxic. Be careful not to get it into your eyes or on your skin. If it should get into your eyes or on your skin, wash it off with large amounts of fresh water and see a doctor at once.
When changing the coolant or when handling coolant con- taining antifreeze that has been drained when repairing the radiator, please contact your Komatsu distributor or request a specialist company to carry out the operation. Antifreeze is toxic. Do not let it flow into drainage ditches or spray it onto the ground surface. Antifreeze is flammable. Do not bring any flame close. Do not smoke when handling antifreeze. NOTICE Use Komatsu Supercoolant wherever available, or use perma- nent type antifreeze coolant. Never use methanol, ethanol, or propanol-based antifreeze. Do not use any water leakage prevention agent, either alone, or in combination with antifreeze.
Do not mix one brand of antifreeze with a different brand. For details of the antifreeze mixture when changing the coolant, see “24.2 WHEN REQUIRED”. 2-82
