COLD WEATHER OPERATION

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.
FUEL AND LUBRICANTS
Change to oil with low viscosity for all components. For details of the specified visicosity, see "RECOMMENDED
FUEL, COOLANT, AND LUBRICANT (PAGE 4-12)".
COOLANT
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.
When changing the coolant or when handling the cooling water containing coolant that has been drained during repair of
radiator, contact your Komatsu distributor or request a specialist company to perform the operation. Coolant is toxic. Do not
let it flow into drainage ditches or spray it onto the ground surface.
NOTICE
Use Komatsu genuine SUPERCOOLANT (AF-NAC) for the coolant. As a basic rule, we do not recommend the use of any coolant
other than SUPERCOOLANT (AF-NAC).
Coolant is already diluted with distilled water, so it is not flammable.
For details of the density of coolant and the interval for changing the coolant, see "CLEAN INSIDE OF COOLING
SYSTEM (PAGE 4-22)".
