PERIODIC SERVICE
BAnti-freeze
To avoid personal injury:
A When using anti-freeze, put on some protection
such as rubber gloves (Anti-freeze contains
poison.).
A If should drink anti-freeze, throw up at once
and take medical attention.
A When anti-freeze comes in contact with the
skin or clothing, wash it off immediately.
A Do not mix different types of Anti-freeze. The
mixture can produce
causing harmful substances.
A Anti-freeze
is extremely
explosive under certain conditions. Keep fire
and children away from anti-freeze.
A When draining fluids from the engine, place
some container underneath the engine body. If
swallowed anti-freeze is harmful.
A Do not pour waste onto the grounds, down a
drain, or into any water source.
A Also, observe the relevant environmental
protection regulations when disposing of anti-
freeze.
If it freezes, coolant can damage the cylinders and
radiator. If the ambient temperature falls below 0
or before a long-term storage, let out cooling water
completely, or mix fresh water with long-life coolant and fill
the radiator and reserve tank with the mixture.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again. Repeat
this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in cooling water in the percentage (%) for
a target temperature. When mixing, stir it up well, and
then fill into the radiator.
4. The procedure for the mixing of water and anti-freeze
differs according to the make of the anti-freeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.
A When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
