COLD WEATHER OPERATION
COLD WEATHER OPERATION INFORMATION
If the ambient temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze.
Follow the instructions described as follows.
FUEL AND LUBRICANTS
Change fuel and oil with ones of low viscosity for all components.
For the details of specified viscosity, see “METHOD FOR USING FUEL, COOLANT AND LUBRICANTS AC-
CORDING TO AMBIENT TEMPERATURE”.
COOLANT
k k
WARNING
• 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 amount of fresh water and see a doctor immediately.
• When handling the cooling water containing coolant that has been drained during changing the
coolant or repair of radiator, contact your Komatsu distributor or request a qualified company to
perform the operation. Coolant is toxic, so never pour it into drainage ditches or drain it onto the
ground surface.
NOTICE
Komatsu recommends using Non-Amine Engine Coolant (AF-NAC) for the coolant.
Non-Amine Engine Coolant (AF-NAC) is already diluted with distilled water, so it is not flammable.
For details on the coolant change interval and the density of Non-Amine Engine Coolant (AF-NAC), see “METH-
OD FOR USING FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”.
DEF
NOTICE
• DEF freezes at –11 °C.
If DEF in DEF tank freezes, it may expand to break the devices in the tank. The parts inside the tank
may be affected. Add DEF to the specified amount for cold weather (below the level of when DEF
may freeze).
For the specified amount of DEF, see “METHOD FOR CHECKING DEF LEVEL AND ADDING DEF
(3-164)”.
• In cold weather, keep the DEF or the machine installed with the DEF in the indoors where the tem-
perature is at -11 °C or higher to prevent the DEF in the tank from freezing.
If DEF or the machine equipped with DEF system is stored at the outside temperature lower than
-11 °C, DEF in the tank may freeze. Ask your Komatsu distributor for discharging of DEF, and keep it
in the condition free from freezing.
• When the ambient temperature is low, the tank shrinks and clearance may occur between the fixing
plate and tank.
Since this clearance disappears as the tank temperature is increased by the machine operation, no
retightening is necessary.
