3.5 Cold weather operation
3.5.1 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 fuel and oil with low viscosity for all components. For
details of the specified visicosity, see "Fuel, coolant and lubri-
cants (4-16)".
Coolant
WARNING
! 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 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 when repairing the
radiator, please contact your KOMATSU distributor. Anti-
freeze is toxic, so do not let it flow into drainage ditches or
spray it on to the ground surface.
! Antifreeze is flammable, so do not bring any flame close. Do
not smoke when handling antifreeze.
NOTE
!
Use KOMATSU Supercoolant (AF-NAC) wherever available,
or use permanent type antifreeze coolant.
!
Never use methanol, ethanol or propanol based antifreeze.
!
Avoid using any leak-preventing agent, regardless if it is sold
separately or in antifreeze.
!
Do not mix one antifreeze with a different brand.
!
When using KOMATSU Supercoolant (AF-NAC), there is no
need to use a corrosion resistor. For details, see "Clean
inside of cooling system (4-35)".
For details of the antifreeze mixture when changing the coolant,
see "Clean inside of cooling system (4-35)".
