ENGLISH
1. If hose clamps are loose or water leaks, tighten hose
clamp securely.
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.

Precaution at overheating
Take the following actions in the event the coolant
temperature be 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. Never 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.
B
Anti-freeze
To avoid personal injury:
A
When using anti-freeze, put on some protection
such as rubber gloves.
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.
A
Keep fire and children away from anti-freeze.
A
Be mindful of the environment and ecology.
Before draining any fluids, find out the correct
way of disposing by checking with local codes.
A
Also, observe the relevant environmental
protection regulations when disposing of oil,
fuel, coolant, brake fluid, filters and batteries.
If it freezes, coolant can damage the cylinders and
radiator. It is necessary, if the ambient temperature falls
below 0 C (32 F), to remove coolant after operating or to
add anti-freeze to it.
1. There are 2 types of anti-freeze available; use the
permanent type (PT) for this engine.
2. Before adding anti-freeze for the first time, clean the
radiator interior by pouring fresh water and draining it
a few times.
3. The procedure for 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.
4. Mix the anti-freeze with water, and then fill in to the
radiator.
A
When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
*At 1.013 x 10 Pa (760 mmHg) pressure
(atmospheric). A higher boiling point is obtained by
using a radiator pressure cap which permits the
development of pressure within the cooling system.
A
The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated anti-freeze.
A
When the coolant level drops due to evaporation, add
water only to keep the anti-freeze mixing ratio less
than 50%. In case of leakage, add anti-freeze and
water in the specified mixing ratio before filling into the
radiator.
A
Anti-freeze absorbs moisture. Keep unused anti-
freeze in a tightly sealed container.
A
Do not use radiator cleaning agents when anti-freeze
has been added to the coolant. (Anti-freeze contains
an anti-corrosive agent, which will react with the
radiator cleaning agent forming sludge which will
affect the engine parts.)
B
Radiator cement
As the radiator is solidly constructed, there is little
possibility of water leakage. Should this happen, however,
radiator cement can easily fix it. If leakage is serious,
contact your local KUBOTA dealer.
