Cleaning Air Cleaner Element
1. Remove the air cleaner cover (3) and primary element (2).
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 the air cleaner primary element (2) :
Once a year or after every sixth cleaning, whichever comes first.
NOTE
■
• Check to see if the evacuator valve (3) 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 dust cup with the arrow

valve will not function and dust will adhere to the element.

or daily when used in a dusty place to get rid of large particles of dust
and dirt.
