4.4.2 Coolant

Use soft water of good quality such as tap water for coolant.

When water with dirt, sand, and/or dust contained, or hard water such as well water (ground water) is
used, this will cause deposits inside radiator or on cylinder head, and will cause engine overheat 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 with water according to the temperature.

Use LLC within the range of its mixing ratio between 35 and 60%.

If LLC in the water exceeds more than 60%, it may decrease its antifreezing effect.
(Upon delivery from the works, LLC density is 55%)

Follow the designated regulations to dispose of LLC (Antifreeze).
