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.
