Coolant
The coolant specication must meet requirements of:
• ASTM D6210
• ASTM D4985
• JIS K-2234
• SAE J814C,J1941,J1034 nebo J2036
To ll the cooling circuit, use the coolant in the mixing ratio of 50%/50% with high-quality water (thermal protection up to -37 °C).
Change the coolant every 2,000 hours, after 2 years at the latest.
NOTE
The machines are lled with a cooling solution with the Bantleon Avia Antifreeze NG coolant, specication SAE J 1034 at the man-
ufacturer's during the production.
It is a coolant based on monoethyleneglycol containing silicates. It does not contain phosphates, nitrates, amines and borates.
There is an Avia NG label placed at the point to ll the coolant into the machine.
Refill the ooling circuit with the same or a completely miscible coolant of the required specifi ation.
If the use of a dierent, immiscible coolant is necessary, the cooling circuit must be completely drained
and cleaned with clean water repeatedly, at least 3 times. However, it is not allowed to use a coolant of a
dierent specifi ation than stated by the engine manufacturer.
The coolant protects the cooling system from freezing, corrosion, cavitation, overheating, etc.
It is forbidden to operate the machine without coolant even for a short time.
It is forbidden to use a coolant of a dierent than prescribed specifi ation and base. The engine and the
cooling system can get damaged and the warranty lost.
Always check the ratio of antifreeze cooling agent in the coolant with a refractometer before the winter
season starts.
Water quality
Do not use hard water with a higher content of calcium and magnesium, which brings calculus formation, and with a higher content
of chlorides and sulphates, which causes corrosion.
• The maximum content of compounds of calcium and magnesium is 170 milligrams – hardness of water.
• The maximum content of compounds of chlorine is 40 milligrams.
• The maximum content of compounds of sulphur is 100 milligrams.
Safety instructions:
1) Protect your hands with protective gloves.
2) In case of ingestion immediately seek medical treatment.
3) In case of contact with skin or clothing immediately wash the aected area with clean water.
4) Do not mix dierent types of coolants. The mixture can cause a chemical reaction with formation of harmful substances.

Coolant
A coolant antifreeze mixture for up to -25° is provided upon delivery from the factory.
For temperatures colder than -25°
, the fluid must be replaced by a suitable coolant
antifreeze mixture.
