Checking Intake Air Line; Every 250 Hours Or 6 Months; Checking Radiator Hoses And Clamp Bands; Precaution At Overheating - Kubota V2403-CR-TIE4-BG Operator's Manual

24 REGULAR CHECKS AND MAINTENANCE WORK
BChecking intake air line
Visually check for cracks, gas leak and anything else
unusual.
Check to see if the lock bolts and nuts are tight enough.
In particular, the hose between the turbo charger and the
intake manifold must be checked for cracks and come-off.
This is because this line will be under high pressure.
See if this hose is deep enough into the pipe. If not,
reinsert the hose deeper. Put the clamp on the hose free
of the bulge of the pipe, and tighten the clamp bolt to the
specified torque.

EVERY 250 HOURS OR 6 MONTHS

BChecking radiator hoses and clamp
bands
To avoid personal injury or death:
A Be sure to check the radiator hoses
and clamp bands periodically. If any
one of the radiator hoses is damaged
or coolant leaks, overheats or severe
burns could occur.
Check to see if radiator hoses are properly fixed every
250 hours of operation or 6 months, whichever comes
first.
1. If any one of the hose clamps is loose or coolant leaks,
tighten the 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 the hoses are swollen,
hardened or cracked.
BPrecaution at overheating
[V3800-TIE4]
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 "REGULAR CHECKS AND
MAINTENANCE WORK" 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 the
radiator fins and tubes;
4. Check to see if the fan belt is too loose; and check to
see if the radiator water pipes are clogged.
