Air Cleaner Element Inspection

Inspect air cleaner element
Every 6 000 km (4 000 miles, 12 months)

Replace air cleaner element

Remove the air duct (1) and inspect air cleaner element (2) for clogging. If it is clogged with dirt, replace it with a new one.

! CAUTION Do not blow the air cleaner element with compressed air.

! CAUTION If driving under dusty condition, replace the air cleaner element more frequently. The surest way to accelerate engine wear is to use the engine without the element or to use a ruptured element. Make sure that the air cleaner is in good condition at all times. Life of the engine depends largely on this component.
