Check Coolant Level - Hitachi ZW 310-6 Operator's Manual

Check Coolant Level

--- every 10 hours (daily)
d
CAUTION: If the engine is kept running with
insufficient coolant, the EGR cooler maybe
damaged due to overheat.
IMPORTANT:
 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.
 Refer to page 7-71 for the coolant specifications.
Check the coolant level at reservoir tank (1).
Sight gauge (3) of expansion tank (1) should be filled with
coolant at normal level.
If not, add the coolant mixture via cap hole (2) on the
expansion tank (1).
f
NOTE: Do not fill up expansion 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 deteriorated.
