Cleaning Air Cleaner Element [Double Type Element] (If
Equipped)
1. Remove the air cleaner cover (2) and primary element (4).
2. Clean the primary element if :
– 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).
– 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. When replacing the air cleaner primary element (4), replace the
secondary element (1) as well : Once a year or after every six
times of cleaning, whichever comes first.
NOTE
• Check to see if the evacuator valve is blocking with dust.
IMPORTANT
• The air cleaner uses a dry element, never apply oil.
• Do not run the engine with filter element removed.
• Be sure to refit the dust cup with the arrow ↑ (on the rear of
cup) upright. If the dust cup is improperly fitted, evacuator
valve will not function and dust will adhere to the element.
• Do not touch the secondary element except in cases where
replacing is required.
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.

Cleaning Fuel Filter
This job should not be done in the field, but in a clean place.
1. Loosen and remove the fuel 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 page G-36.)
IMPORTANT
• 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, mark sure the fuel tank is
less than half-full.
