BChecking Radiator Hoses and Clamps
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 earlier
as required, if hoses are found to be swollen, hardened or
cracked.

which is called "Precaution overheating". Take these
actions if the engine's the alarm lamp lights up.
