1. Replacing the fuel hoses and the
clamps
WARNING
To avoid personal injury or death:
• A broken fuel line will cause the fuel to leak. Be
sure to check the fuel line. Fire or injuries may
result if a fuel line is leaking.
• Make sure that the engine is cool before
disconnecting fuel lines.
Rubber parts like the fuel lines are likely to age even if
the engine is not used regularly. Therefore, it is
necessary to replace fuel lines with new ones once
every 2 years or sooner if they are damaged.
1. Regularly check that the fuel lines and clamps are
not loose or damaged.
2. When the fuel line has been replaced, be sure to
bleed air from the fuel line.

IMPORTANT :
• When replacing the fuel lines, take special
care to prevent dirt and other foreign matter
from entering the fuel system. Entry of
foreign matter in the fuel system will likely
cause serious damage.
2. Changing the coolant
WARNING
To avoid personal injury or death:
• Never open the plug immediately after the
engine has stopped, or hot coolant may rush
out, causing scalding.
1. Open the plug under the radiator to drain the
coolant.
