Cleaning Air Cleaner Primary Element
1. Open the hood and remove the air cleaner cover and
the primary element.
2. Clean the primary element:
(1) When dry dust adheres to the element, blow
compressed air from the inside, turning the
element. Pressure of compressed air must be
under 205 kPa (2.1 kgf/cm , 30 psi).
(2) When carbon or oil adheres to the element, soak
the element in detergent for 15 minutes then wash
it several times in water, rinse with clean water
and dry it naturally. After element is fully dried,
inspect inside of the element with a light and
check if it is damaged or not.
3. Replace air cleaner primary element:
Once yearly or after every sixth cleaning, whichever
comes first.

Check to see if the evacuator valve is blocked with
dust.

The air cleaner uses a dry element, never apply oil.
A
Do not run the engine with filter element removed.
A
Be sure to refit the cover with the arrow
(on the rear
of cover) upright. If the cover is improperly fitted,
evacuator valve will not function and dust will adhere
to the element.
A
Do not touch the secondary element except in cases
where replacing is required.
(See "Replacing Air Cleaner Primary Element and
Secondary Element" in "EVERY 1 YEAR" in

Evacuator Valve
Open the evacuator valve once a week under ordinary
conditions - or daily when used in a dusty place - to get rid
of large particles of dust and dirt.
B
Cleaning Fuel Filter
This job should not be done in the field, but in a clean
place.
1. Loosen and remove the filter bowl, and rinse the inside
with kerosene.
2. Take out the element and dip it in the kerosene to
rinse.
3. After cleaning, reassemble the fuel filter, keeping out
dust and dirt.
4. Bleed the fuel system.
(See "SERVICE AS REQUIRED" in "PERIODIC
SERVICE OF THE TRACTOR" section.)
A
When the fuel filter bowl has been removed, fuel stops
flowing from the fuel tank. If the fuel tank is almost full,
however, the fuel will flow back from the fuel return
pipe to the fuel filter. Before checking, make sure the
fuel tank is less than half-full.
