[Handling of Anti-Freeze]
Anti-freeze has an effect of lowering the freezing point of water. This tractor is filled with international genuine anti-freeze
when delivered from the factory. As the freezing point may differ depending on the mixture ratio, refer to the following table
in very cold weather to ensure safety.
Anti-Freeze Mixture Ratio
Outdoor Temp (‘F) 23 14 5 -4 -13 -22
Ratio (%) 82 73 66 61 55 49
Anti-Freeze (%) 18 27 34 39 45 51
[Precaution]
• When replacing the coolant, add anti-corrosive solution and run the engine for about five minutes to mix it with the water.
• For correct mixture ratio, refer to the manufacturer’s instructions.
• When refilling the coolant, add only tap water.
• As anti-freeze expires in one year, replace the coolant every year.
