2. Replace hoses and tighten hose clamps securely, if
radiator hoses are swollen, hardened or cracked.
Replace hoses and hose clamps every 2 years, or earlier,
if checked and found that hoses are swollen, hardened or
cracked.
BPrecaution at overheating
Take the following actions in the event the coolant
temperature is nearly or more than the boiling point, what
is called "Overheating". Take these actions if the engine's
alarm buzzer sounds or the alarm lamp lights up.
1. Stop the engine operation in a safe place and keep
the engine unloaded idling.
2. Do not stop the engine suddenly. Stop it after about 5
minutes of unloaded idling.
3. If the engine stalls within about 5 minutes of running
under no load, immediately leave and keep yourself
away from the machine. Do not open the hood and any
other part.
4. Keep yourself and others well away from the engine
for further 10 minutes or while the steam blown out.
5. Checking that there gets no danger such as burn, get
rid of the causes of overheating according to the
manual, see "Troubleshooting" section. And then, start
again the engine.
BCleaning radiator core(outside)
If dust is between the fin and tube, wash it away with
running water.
A Do not clean radiator with firm tools such as spatulas
or screwdrivers. They may damage specified fin or
tube. It can cause coolant leaks or decrease coolings
performance.
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.
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 C
(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 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.
