Antifreeze:
If the air temperature is below 0℃(32℉), add antifreeze and soft water to the cooling system.
In general, the ratio of antifreeze should be between 30% and 60%.
If the ratio is less than 30%, the cooling system will be rusted; if the ratio is more than 60%,
the engine will be overheated. Use 50% water and 50% glycol antifreeze, the engine can
operate at the -37℃ perennially.
⚫ Only maintain in the first inspection.
⚫ When the machine is delivered, 30% of antifreezing fluid has been filled in the
cooling system.
⚫ Operate the machine at dusty areas, maintenance interval should be shortened.
