5.5.14 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.

When a person has drunk LLC (Antifreeze) by accident, make him vomit and see a doctor im-
