Changing Engine Oil Filter Cartridge
CAUTION
• Be sure to stop the engine before changing the oil filter
cartridge.
1. Remove the engine oil filter cartridge (1) with the filter wrench.
2. Apply engine oil slightly to the rubber gasket of new cartridge.
3. Install the new cartridge, screwing it in by hand.
Over-tightening may cause deformation of the rubber gasket.
4. After the cartridge has been changed, the engine oil level
normally lowers a little. Add engine oil to proper level.
IMPORTANT

• To prevent serious damage to the engine, replacement oil
filter cartridge must be highly efficient. Use only a genuine
KUBOTA filter cartridge or its equivalent.

Checking Fuel Line
CAUTION
• Stop the engine when attempting the check and change
prescribed below.
• Remember to check the fuel line periodically. The fuel line
is subject to wear and aging, fuel may leak out onto the
running engine, causing a fire.
1. Check to see that all fuel lines (2) and hose clamps (1) are tight
and not damaged.
2. If lines and clamps are found worn or damaged, replace or repair
them at once.
3. The fuel line (2) is made of rubber and ages regardless of period
of service. Replace the fuel line (2) together with the hose clamp
(1) every two years and securely tighten.
4. However if the fuel lines (2) and hose clamps (1) are found
damaged or deteriorated earlier than two years, then change or
remedy.
IMPORTANT

• When the fuel line is disconnected for change, close both
ends of the fuel line with a piece of clean cloth or paper to
prevent dust and dirt from entering. Entrance of dust and
dirt causes malfunction of the fuel injection pump.
addition, particular care must be taken not to admit dust and
dirt into the fuel pump.
