[3] CHECK POINTS OF EVERY 50 HOURS

Replacing Oil Filter Cartridge
CAUTION
• Be sure to stop the engine before replacing oil filter
cartridge.
• Allow engine to cool down sufficiently, oil can be hot and
cause burns.
1. Remove the oil filter cartridge (1) with the filter wrench.
2. Apply a slight coat 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 level
normally decreases a little. Thus, operate the engine for a while
and check for oil leaks through the seal before checking the
engine oil level. Add oil if necessary.
IMPORTANT
• To prevent serious damage to the engine, replacement
element must be highly efficient. Use only a KUBOTA
genuine filter or its equivalent.
NOTE
• Wipe off any oil sticking to the machine completely.

Cleaning Primary Air Cleaner Element
1. Open the evacuator valve once a week under ordinary
conditions - or daily when used in a dusty place. This will get rid
of large particles of dust and dirt.
2. Wipe the inside air cleaner clean with cloth if it is dirty or wet.
3. 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 (2.09 kgf/cm
30.5 psi).
Keep reasonable distance between the nozzle and the filter.
4. If the primary element (4) is stained heavily, replace it soon.
At this time, replace the secondary element (3) too.
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.
Overservicing may cause dirt to enter the engine causing
premature wear. Use the dust indicator as a guide on when
to service.
NOTE
• Avoid touching the element except when cleaning.
• Replace the element once a year or every 6th cleaning.
• The secondary element (3) should be removed only if it is
to be replaced.
• To protect the engine, do not remove the secondary
element (3) in servicing the primary element (4).
