6.9.1 Change Coolant
Be sure to stop the machine and allow time to cool.
Loosen the radiator cap one notch. After the coolant
water is sufficiently cooled and the inner pressure is
released, remove the cap.
If this procedure is neglected, the inner pressure can
blow off the cap. Steam jetting out of the radiator could
result in serious injury. Follow this procedure under all
circumstances.
LLC (Antifreeze) is a toxic material.
If a person has ingested LLC (Antifreeze) by accident, call poison control and or emergency
services immediately.
If a person gets LLC (Antifreeze) in his eyes, wash eyes with clean running water and call a
doctor immediately.
When LLC (Antifreeze) is stored, put it in a container with an indication saying "LLC
(Antifreeze) inside" and seal it up. Keep it in a place away from children.
Beware of flames around antifreeze.
Follow the designated regulations to dispose of LLC (Antifreeze) properly.
Use soft water of good quality such as distilled water for coolant.
When dirt, or hard water is used, this will cause deposits inside radiator or on cylinder head,
and may cause engine overheating due to poor flow of coolant.
When the unit is used in a cold region and possible freezing is expected, it is recommended
to use LLC (Antifreeze) for the coolant.
Adjust mixing ratio of LLC (Antifreeze) with water according to the temperature.
Use LLC (Antifreeze) within the range of its mixing ratio between 35 and 60%.
If LLC (Antifreeze) in the water exceeds more than 60%, it may decrease its antifreezing
effect and could cause overheating.
