32 PERIODIC SERVICE
C Checking radiator hoses and clamps
CAUTION
To avoid personal injury:
A Be sure to check radiator hoses and
hose clamps periodically. If radiator
hoses are damaged or coolant leaks
out, overheating can 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
clamps securely.
2. Replace hoses and hose clamps if radiator hoses
are swollen, hardened or cracked.
Replace hoses and hose clamps every 2 years, or ear-
lier as required, if hoses are found to be swollen, hard-
ened or cracked.

C Precaution 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, in-
spect it, referring to the relevant description in "SER-
VICE INTERVALS" and "PERIODIC SERVICE" section.
A Coolant
If the coolant temperature warning lamp lights up or if
steam or coolant does not stop squirting from the radia-
tor 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.
C Cleaning 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 the delicate fins
or tubes. It can cause coolant leaks or decrease
cooling performance.
A Be careful to keep water off of electrical parts.
C Cleaning the radiator
Clean the cooling system of the engine every 500 hours.
In addition, clean it before adding anti-freeze and before
stopping use of anti-freeze.
B Anti-freeze
CAUTION
To avoid personal injury:
A When using anti-freeze, put on
some protection such as rubber
gloves (Anti-freeze
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
conditions. Keep fire and children
away from anti-freeze.
A When draining fluids from the
engine, place
underneath the engine body.
A Do not pour
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.
