“ LOW”
IMPORTANT:

Do not start engine without coolant.

Use clean, fresh water and anti-freeze
to fill the radiator and recovery tank.

When the anti-freeze is mixed with
water, the antifreeze mixing ratio must
be less than 50%.

Securely tighten radiator cap. If the cap
is loose or improperly fitted, water may
leak out and the engine could overheat.
■
Anti-Freeze
CAUTION
To avoid personal injury:

When using antifreeze, put on some
protection such as rubber
gloves.(Antifreeze contains poison.)

If you should drink antifreeze, throw up
at once and take medical attention.

When antifreeze comes in contact with
the skin or clothing, wash it off
immediately.
。

Do not mix different types of Antifreeze.
The mixture can produce chemical
reaction causing harmful substances.

Antifreeze is extremely flammable and
explosive under certain conditions.
Keep fire and children away from
antifreeze.
When draining fluids from the engine, place
some container underneath the engine body.

Do not pour waste onto the grounds, down a
drain, or into any water source.

Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
If it freezes, coolant can damage the cylinders
and radiator. If the ambient temperature falls
below 0 (32
℃
°
F) or before a long-term storage,
let out cooling water completely, or mix fresh
water with long-life coolant and fill the radiator
and recovery 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
4. The procedure for the mixing of water and
antifreeze differs according to the make of
the antifreeze and the ambient temperature.
Refer to SEA J1034 standard, more
specifically also to SAE J814c.
IMPORTANT:

When the antifreeze is mixed with water, the
antifreeze mixing ratio must be less than 50%.
