Check Coolant Level - Hitachi ZW180 Operator's Manual

1
Check Coolant Level --- every 10 hours (daily)
ZW310
WARNING: Do not remove cap (4) until the coolant
temperature in the radiator is cool. Hot steam may
spout out, possibly causing severe burns. After the
coolant temperature cools, slowly loosen cap (4) to
release the inside air pressure before removing cap
(4).
Check the coolant level at expansion tank (1) on ZW310. The
normal coolant level on ZW310 is between FULL (2) and LOW (3)
marks in the level gauge.
In case no coolant is present in expansion tank (1) on
ZW310, supply the coolant via the cap hole on 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 ef-
fect in the coolant will become deteriorated.
