A
When the anti-freeze is mixed with water, the anti-
freeze mixing ratio must be less than 50%.
*At 1.013x10 Pa (760mmHg) 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 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.
*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 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.
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.
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.
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 205kPa
(2.1kgf/cm , 30psi).
5. When carbon or oil adheres to the element, soak the
element in detergent for 30 minutes, then wash it
several times in water, rinse with clean water and dry
it naturally.
6. After the element is fully dried, inspect the inside of the
element with a light, and check if it is damaged or not.
(referring to the instructions on the label attached to
the element.)
7. Replace the element every year or every 6 cleanings.
A
Make sure the wing bolt for the element is tight
enough. If it is loose, dust and dirt may be sucked in,
wearing down the cylinder liner and piston ring earlier
and thereby resulting in poor power output.
A
Do not overservice the air cleaner element.
Overservicing may cause dirt to enter the engine
causing premature wear. Use the dust indicator as a
guide on when to service.
