COLD WEATHER OPERATION INFORMATION

If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as follows.
Fuel and Lubricants
Change to fuel and oil with low viscosity for all components. For details of the specified visicosity, see
"RECOMMENDED FUEL, COOLANT, AND LUBRICANT (PAGE 4-10)".
Cooling System Coolant
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 containing 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.
NOTICE
Please use Komatsu genuine supercoolant (AF-NAC) for the coolant. As a basic rule, we do not recommend the use of any coolant
other than Komatsu genuine supercoolant.
The Supercoolant is already diluted with distilled water, so it is not flammable.
For details of the density of the Supercoolant and the interval for changing the coolant, see "CLEAN INSIDE OF
COOLING SYSTEM (PAGE 4-27)".
