Before starting a new machine, the
coolant level n the radiator should be
checked, after that, it should be checked
every day or every 10 hours.
Remove the radiator (water tank) cap
and check the level of the coolant. When
the engine is cold, the coolant level shall
be 20 mm below the water filler port.
Observe the level of the coolant level in
the balance tank. If the engine is cold, the
coolant level shall be between the
highest and lowest water levels.
Warning: When the radiator cap is unscrewed, hot coolant will spray out.
Cover unscrewing method:After the system cools down, slightly loosen the
cover and wait for the pressure to fully release. If the cover is unscrewed too
quickly, coolant may spray out, which may cause personal injury.
