GENERAL
Replacing Oil Filter Cartridge
CAUTION
• Be sure to stop the engine before changing filter cartridge.
1. Remove the oil filter cartridge (1) with the filter wrench.
2. Apply a slight coart of oil onto the new cartridge gasket.
3. To install the new cartridge, screw it in by hand. Over tightening
may cause deformation of rubber gasket.
4. After the new cartridge has been replaced, the engine oil
normally decrease a little. Thus see that the engine oil does not
leak through the seal and be sure to read the oil level on the
dipstick. Then, replenish the engine oil up to the specified level.
IMPORTANT
■
• To prevent serious damage to the engine, replacement
element must be highly efficient. Use only a KUBOTA
genuine filter or its equivalent.

[3] CHECK POINTS OF EVERY 50 HOURS
Checking Air Cleaner Element
1. To clean the element, use clean dry compressed air on the inside
of the element.
Air pressure at the nozzle must be under 205 kPa (2.1 kgf/cm
2
,
30 psi).
2. If the element is stained with carbon or oil, replace the element.
IMPORTANT
■
• Make sure the wing bolt for the element is tight enough. If it
is loose, dust and dirt may be sucked, wearing down the
cylinder liner and piston ring earlier and thereby resulting in
poor power output.
• Do not overservice the air cleaner element.
NOTE
■
• Replace the element once a year or every 6th cleaning.

CAUTION
• Stop the engine when attempting the check and replace 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.
Checking Fuel Hose (Gasoline Fuel Line)
Check the fuel hoses every 100 hours of operation.
1. Since the fuel hose (2) is made of rubber, it ages regardless of
the period of service.
Replace the fuel hose together with the clamp every two years.
2. However, if the fuel hose and clamp are found to be damaged or
deteriorate earlier than two years, then replace or remedy.
3. After the fuel hose and the clamp have been replaced, bleed the
fuel system.
