4.3.4 - Checking radiator hoses and clamp
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.
4.3.5 - 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,
inspect it, referring to the relevant description in "MAINTENANCE" and "PERIODIC SERVICE" section.
4.3.6 - 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.
5. Check to see if radiator water pipe is clogged.
4.3.7 - Cleaning radiator core (outside)
If dust is between the fin and tube, wash it away with running water.
To avoid personal injury :
• Be sure to check radiator hoses and hose clamps periodically. If radiator hose is damaged or coolant leaks, overheats
or severe burns could occur.
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.
