3.5 Operation in cold weather
3.5.1 Precautions for operation in cold weather
At low temperatures, it may become difficult to start the engine,
and the coolant may freeze. Use the following precautions:
 Change to low-viscosity oil for all components.
 Use winter fuel.
For details see “Fuel, lubricants, and coolants; quantities
(5-16)”.
 Fill the windshield washer system with antifreeze.
 Check the coolant.
WARNING
 Antifreeze is toxic. Be careful to avoid contact with eyes or
skin. If antifreeze should contact your eyes or skin, wash it off
with a large amount of fresh water and see a doctor at once.
 When changing the coolant or when handling coolant con-
taining antifreeze that has been drained while repairing the
radiator, please contact your Komatsu distributor. Antifreeze
is toxic. Prevent it from leaking into drainage ditches or spill-
ing on the ground.
 Antifreeze is flammable. Keep away from open fire. Do not
smoke when handling antifreeze.
NOTICE
 Please use the original Komatsu antifreeze, Supercoolant
(AF-NAC). We recommend using Komatsu genuine Super-
coolant exclusively.
 Do not mix antifreeze agents of different brands.
For details see “Coolant (5-12)” and “Cooling system – clean-
ing internal area of the cooling system (5-32)”.
