Check Coolant Level --- every 10 hours (daily)
ZW180, ZW220, ZW250
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 reservoir tank (1) on ZW180, ZW220
and ZW250. The normal coolant level on ZW180, ZW220 and
ZW250 is between FULL (2) and LOW (3) marks on side surface
of reservoir tank (1).
In case no coolant is present in reservoir tank (1) on ZW180,
ZW220 and ZW250, supply the coolant via the cap hole 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 ef-
fect in the coolant will become deteriorated.
