(3) Empty space
(4) Maximum fuel level
([F] mark)
Check the fuel level. Take care that the fuel tank does
not become empty.
Fuel tank capacity
IMPORTANT :
• Do not mix oil with gasoline.
• Tighten the fuel cap until it clicks.
• Do not use a fuel cap other than one approved
by KUBOTA.
• Do not permit dirt, trash or water to get into the
fuel system.
• Be careful not to spill fuel while refueling. If a
spill should occur, wipe it off at once, or it may
cause a fire.
• Do not use old fuel.
Use only unleaded gasoline with an octane rating index
of 87 or higher.
NOTE :
• Use fuel within approximately 30 days after
purchase to avoid deterioration in fuel quality,
or add fuel stabilizer to keep fuel fresh and
stabilized.
• Fuel blend differs from season to season for the
best seasonal engine performance. To prevent
engine performance troubles such as vapor
lock or hard starting, use fuel within the season
in which the fuel is purchased.
• Infrequent use of the engine during a season
can make fuel stale in the fuel tank of the
machine. Stale fuel condition can cause engine
performance troubles due to varnished and
plugged carburetor components.
• Seal the fuel storage container tightly and store
it out of sunlight and heat to prevent fuel
degradation.
• Condensation in the fuel tank may occur
because of various operating or environmental

conditions. To reduce condensation and to
avoid affecting the machine operation, fill the
fuel tank at the end of daily operations.
Use of alcohol mixed gasoline
Only use gasoline containing ethanol when the ethanol
is 10% or less of the fuel. When using gasoline
containing MTBE, the MTBE is 15% or less of the fuel
mixture. The use of methanol additive is not
recommended. For best results, use unleaded fuel with
a minimum of 87 octane.
3. Checking and cleaning the air
intake screen
WARNING
To avoid serious injury or death:
• Be sure to stop the engine and remove the key
before cleaning.
• Make sure that the engine is cool to the touch
before cleaning.
IMPORTANT :
• The air intake screen and air intake area must
be clear of debris to prevent the engine from
overheating.
Daily or after every 5 hours of operation, make sure the
air intake screen and the air intake area are clean.
Dirt or chaff around the air intake screen, air intake
area, or the engine cooling area decrease cooling
performance.
1. Check that the air intake screen is clear of grass
clippings and debris.
2. If the screen is dirty, clean it with a brush or cloth.
3. Remove the dust and all foreign material from the
engine plate.
