BChecking radiator hoses and clamp
bands
To avoid personal injury or death:
A Be sure to check radiator hoses and
clamp bands periodically. If radiator
hose is damaged or coolant leaks,
overheats or severe burns could
occur.
Check to see if radiator hoses are properly fixed every
200 hours of operation or 6 months, whichever comes
first.
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.
BPrecaution at overheating
The event that the coolant temperature is nearly or more
than the boiling point is called "OVERHEATING".
While running, make the following checks to see that all
parts are working correctly. If anything is unusual,
inspect it, referring to the relevant description in
"MAINTENANCE" and "PERIODIC SERVICE" section.
C Coolant
If the coolant temperature warning lamp lights up or if
steam or coolant does not stop squirting from the radiator
overflow pipe, turn off the load and keep the engine
idling (COOLING-DOWN) for at least 5 minutes to let it
cool down gradually. Then stop the engine and take the
following inspection and servicing.
1. Check to see if the coolant runs short or if there is any
coolant leak;
2. Check to see if there is any obstacle around the
cooling air inlet or outlet;
3. Check to see if there is any dirt or dust between
radiator fins and tube;
4. Check to see if the fan belt is too loose; and
5. Check to see if radiator water pipe is clogged.
BCleaning radiator core (outside)
If dust is between the fin and tube, wash it away with
running water.
A Do not clean radiator with firm tools such as spatulas
or screwdrivers. They may damage specified fin or
tube. It can cause coolant leaks or decrease cooling
performance.
PERIODIC SERVICE
BAnti-freeze
To avoid personal injury or death:
A When using anti-freeze, put on some
protection such as rubber gloves.
(Anti-freeze is poisonous.)
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
emergency
number
assistance.
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
conditions. Keep fire and children
away from anti-freeze.
A When
draining
engine,
place
underneath the engine body.
A Do not pour waste onto the grounds,
down a drain, or into any water
source.
A Also,
observe
environmental
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.
