ENGLISH
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
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 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 minimum glycol content in the
concentrated anti-freeze.
BATTERY
To avoid personal injury:
A Be careful not to let the battery
electrolyte contact your body or
clothing.
A Wear eye protection and rubber
gloves, since the diluted sulfuric acid
solution burns skin and eyes, and
eats holes in clothing. Should this
occur, immediately wash it off with
running water and get medical
attention.
Mishandling of the battery shortens the service life and
adds to maintenance costs. Obtain the maximum
performance and the longest life of the battery by
handling properly and with care.
Engine starting will be difficult, if the battery charge is low.
Be sure to keep the battery in a fully charged state for best
performance and battery life.
BBattery Charging
To avoid the possibility of battery
explosion:
The batteries come in two types:
refillable and non-refillable. For using
the refillable type battery, follow the
instructions below.
A DO NOT use or charge the battery if
the fluid level is below the LOWER
(lower limit level) mark.
Otherwise, the battery component
parts may deteriorate prematurely,
which will shorten the battery’s
service life or may cause an
explosion.
Immediately, add distilled water until
the battery’s fluid level comes
somewhere between the UPPER and
LOWER levels.
A When the battery is being activated,
hydrogen and oxygen gases in the
battery are extremely explosive.
Keep open sparks and flames away
from the battery at all times,
especially when charging the
battery.
A When charging the battery, ensure
the vent caps are securely in place (if
equipped).
A When disconnecting the cable from
the battery, start with the negative
terminal, and when connecting them,
start with the positive terminal first.
A DO NOT check the battery charge by
placing a metal object across the
terminals. Use a voltmeter or
hydrometer.
