Replacing Engine Oil Filter
To avoid personal injury:
A
Be sure to stop the engine and remove the key
before changing the oil and the oil filter.
A Allow engine to cool down sufficiently; oil can
be hot and may cause burns.
1. The oil filter must be changed every 200 service hours.
2. Apply a slight coat of oil onto the rubber gasket of new
filter.
3. Tighten the filter quickly until it contacts the mounting
surface. Tighten filter by hand an additional 1/2 turn
only.
4. After the new filter has been replaced, the engine oil
level normally lowers a little. Add engine oil to proper
level. Check for oil leaks around filter gasket.
A To prevent serious damage to the engine,
replacement element of the recommended type must
be used. Use only a genuine KUBOTA filter or its
equivalent.
B Checking Spark Plug Condition & Gap
Remove the spark plugs, check condition, and reset the
gap or replace with new plugs as necessary.
1. Open the hood.
2. Before removing spark plugs, clean the area around
the base of the plug to keep dirt and debris out of the
engine.
3. Disconnect the spark plug cap from spark plugs.
4. Use a spark plug wrench to remove the spark plugs.
5. Remove plugs and check its condition.
Replace the plug if worn or reuse is questionable.
6. Inspect spark plugs for cracked porcelain, pitted
electrodes, or other wear and damage. Replace the
spark plug if necessary.
A

abrasive grit. Some grit could remain in the spark plug
and enter the engine, which may cause extensive
wear and damage.
