COLD WEATHER OPERATION INFORMATION 3
If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as fol-
lows.
Fuel and Lubricants 3
Change to fuel and oil with low viscosity for all components. For details of the specified visicosity, see “RECOM-
MENDED FUEL, COOLANT, AND LUBRICANT (4-11)“.
Cooling System Coolant 3
q Coolant 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.
q When changing the coolant or when handling the coolant containing coolant that has been drained
during repair of the radiator, please contact your Komatsu distributor or request a specialist company
to carry out the operation. Coolant is toxic. Do not let it flow into drainage ditches or spray it onto the
ground surface.
Please use Komatsu genuine supercoolant (AF-NAC) for the coolant. As a basic rule, we do not recom-
mend the use of any coolant other than Komatsu genuine supercoolant (AF-NAC).
The coolant is already diluted with distilled water, so it is not flammable.
For details of the density of the coolant and the interval for changing the coolant, see “CLEAN INSIDE OF COOL-
ING SYSTEM (4-27)“.
