NOTE:
✱
Before leaving the Hitachi factory, the cooling system is filled with a mixture of water and Genuine
Hitachi Long-Life Coolant. As long as Genuine Hitachi Long-Life Coolant is used, the service inter-
vals between changing the coolant is once every two years, or every 4000 hours, whichever comes
first.
Coolant
Fill the radiator with soft, pure tap or bottled water.
Anti-rust agent
Add approximately 3.9 L (4.1 US qt) of anti-rust agent to
the new coolant when the coolant is changed.
It is not necessary to add anti-rust agent when antifreeze
is used.
Antifreeze
If the air temperature is expected to fall below 0
°
C (32
°
F),
fill the cooling system with an antifreeze and soft water
mix. As a general rule, the ratio of antifreeze should
range between 30% and 50% as shown in the table be-
low. If the ratio is below 30%, the system may develop
rust, and if it is above 50%, the engine may overheat.
