4.4 - AIR CLEANER
Since the air cleaner employed on this engine is a dry type, never apply oil
to it :
1. Open the evacuator valve once a week under ordinary condi-
tions - or daily when used in a dusty place. This will get rid of
large particles of dust and dirt.
2. Wipe the inside air cleaner clean with cloth if it is dirty or wet.
3. Avoid touching the primary element except when cleaning.
4. When dry dust adheres to the primary element, blow com-
pressed air from the inside turning the element. Pressure of
compressed air must be under 205 kPa (2.1 kgf/cm2, 30 psi).
5. When carbon or oil adheres to the primary element, soak the
element in detergent for 30 minutes, then wash it several ti-
mes in water, rinse with clean water and dry it naturally.
6. After the primary element is fully dried, inspect inside of the
element with a light and check if it is damaged or not.
7. Replace the primary element every year or every 6 cleanings.
If the primary element is stained heavily, replace it soon. At
this time, replace the secondary element too.
8. The secondary element should be removed only if it is to be
replaced.
9. To protect the engine, do not remove the secondary element
in servicing the primary element.

• Make sure hooking clip for cover for the element is tight enough. If it is loose, dust and dirt may be sucked in, wearing
down the cylinder liner and piston ring earlier, and thereby resulting in poor power output.
• Do not overservice the air cleaner element. Overservicing may cause dirt to enter the engine causing premature wear.
Use the dust indicator as a guide on when to service.
• Be sure to refit the cover with the arrow (on the rear of the cover) upright. If the cover is improperly fitted, the evacuator
valve will not function and dust will adhere to the element.
