Check Coolant Level - Hitachi ZW 550-6 Operator's Manual

Check Coolant Level

--- every 10 hours (daily)
Check the coolant level at reservoir tank (1). The normal
coolant level is between the FULL and LOW marks on side
surface of reservoir tank (1).
In case no coolant is present in reservoir tank (1), add the
coolant mixture via cap hole (2) on reservoir tank (1).
 When refilling a long life coolant (LLC), use the same
brand product and the same mixture ratio as already
used in the machine.
 If only water is refilled, the mixture ratio in the long life
coolant (LLC) is diluted so that anti-rust and antifreeze
effect in the coolant will become diluted and less
affective.
IMPORTANT: If the coolant level is low, EGR cooler is
heated up, and damaged.
