Anti-freeze
CAUTION
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
chemical reaction causing harmful
substances.
A Anti-freeze is extremely flammable
and 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.
Always use a 50/50 mix of long-life coolant and clean
soft water in KUBOTA engines.
Contact KUBOTA 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, flush
the radiator with fresh water. Repeat this procedure
2 or 3 times to clean up the radiator and engine block
from 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 anti-
freeze differs according to the make of the anti-
freeze. Refer to SAE J1034 standard, more
specifically also to SAE J814c.
*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.
5. Adding the LLC
(1) Add only water if the coolant level reduces in the
cooling system by evaporation.
(2) If there is a coolant leak, add the LLC of the same
manufacturer and type in the same coolant percent-
age.
*Never add any long-life coolant of different manufactur-
er. (Different brands may have different additive compo-
nents, 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 anti-corrosive
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 anti-freeze.
AIR CLEANER
Since the air cleaner employed on this engine is a dry
type, never apply oil to it.
1. Open the evacuator valve once a week under
ordinary conditions - or daily when used in a dusty
place. This will get rid of large particles of dust and
dirt.
2. Wipe the inside air cleaner clean with cloth if it is dirty
or wet.
3. Avoid touching the element except when cleaning.
4.
When dry dust adheres to the element, blow
compressed air from the inside turning the
element. Pressure of compressed air must be
under 205 kPa (2.1 kgf/cm , 30 psi).
