BAnti-Freeze
To avoid personal injury:
A When using antifreeze, put on some protection
such as rubber gloves (Antifreeze contains
poison.).
A If it is swallowed, seek immediate medical help.
Do NOT make a person throw up unless told to
do so by poison control or a health care
professional. Use standard first aid and CPR
for signs of shock or cardiac arrest. Call your
local Poison Control Center or your local
emergency number for further assistance.
A When antifreeze comes in contact with the skin
or clothing, wash it off immediately.
A Do not mix different types of Antifreeze.
The mixture can produce chemical reaction
causing harmful substances.
A Antifreeze
is
explosive under certain conditions. Keep fire
and children away from antifreeze.
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
antifreeze.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Consult your local KUBOTA Dealer concerning coolant for
extreme conditions.
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
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then fill into the radiator.
4. The procedure for the mixing of water and antifreeze
differs according to the make of the antifreeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.

5. Adding the LLC
(1) Add only water if the mixture reduces in amount
by evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacturer and type in the same mixture
percentage.
D Never add any long-life coolant of different
manufacturer. (Different brands may have
different additive components, and the engine
may fail to perform as specified.)
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anticorrosive agent.
If mixed with the cleaning agent, sludge may build up,
adversely affecting the engine parts.
7. Kubota's genuine long-life coolant has a service life of
2 years. Be sure to change the coolant every 2 years.
A The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated antifreeze.
