5.5.13 Change Coolant
[1,000 hours or every 2 years]
Be sure to stop the machine and allow time to cool. Then
loosen the radiator cap one notch. After the coolant water
is sufficiently cooled and the inner pressure is released,
take the cap off.
If this procedure is neglected, the inner pressure can blow
off the cap. Steam jetting out of the radiator could result in
causing scalding. Follow this procedure under all circum-
stances.
LLC (Antifreeze) is a toxic material.
When a person has drunk LLC (Antifreeze) by accident, make him vomit and see a doctor im-
mediately.
When a person gets LLC (Antifreeze) in his eyes, wash the eyes with clean running water and
make him see a doctor immediately.
When LLC (Antifreeze) is stored, put it in a container with an indication saying “LLC (Antifreeze)
inside” and seal it up, then keep it in a place away from children.
Beware of flames.
① To drain coolant, first unfasten and take off
the cap“1”of the radiator, open the drain
