Cleaning Air Cleaner Primary Element
1. Remove the air cleaner cover and primary element.
2. Clean the primary element :
• 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
2
,
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. Replace air cleaner primary element :
Once yearly or after every six times of cleaning, whichever
comes first.
NOTE
• Check to see if the evacuator valve is blocked 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 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.
• Do not touch the secondary element except in cases where
replacing is required.

Evacuator Valve
Open the evacuator valve (4) once a week under ordinary
conditions or daily when used in a dusty place to get rid of large
particles of dust and dirt.

1. Close the fuel filter shutoff-valve (1).
2. Unscrew the screw ring and remove the fuel filter bowl (2), and
rinse the inside with kerosene.
3. Remove the filter element (4) and dip it in the kerosene to rinse.

dirt.
5. Bleed the fuel system. (See page G-43.)
