Use suitable water to dilute the antifreeze. (For
more information see
“
Coolant
”
on page 5-11
.)
Density meter is recommended to control the
mixture ratio.
Prepare a container to hold the drained cool-
ant. The container's capacity should be larger
than the speci
fi
c volume of coolant.
Prepare a hose to transfer anti-freezing cool-
ant and water.
●
Antifreeze is flammable. Naked fire
should be kept away from antifreeze.
Antifreeze is poisonous. Be careful
when opening the drain valve in order
to prevent skin contract of the water
containing antifreeze. In case of con-
tact with your eyes, flush with large
amount of clean water and refer to
medical care immediately.
●
To change the coolant or drain the ra-
diator coolant when repairing your ma-
chine, consult professional company
or your Sany distributor to dispose the
coolant containing antifreeze. Never
drain the coolant to sewage or onto
ground since the antifreeze is poison-
ous.
WARNING
1. Park your machine on a level ground and
then shut off the engine. Lock out and tag
out your machine before proceeding. See
“Lock-out and tag-out” on page 2-60.
2. Remove slowly the radiator cap (1) to
relieve pressure only when the coolant is
cool enough for you to touch the radiator
cap with your bare hand.
