AIR FILTER_______________________________________________________________

Check the service indicator daily. If red band appears in the
window (B) replace the element.
Do not remove the element for inspection or cleaning.

injecting dust and other impurities into the engine.
When service is required, first clean the outside of the filter
housing, remove the old element as gently as possible, and
discard.
1. Carefully clean the inside of the filter housing without
allowing dust into the air intake.
2. Inspect the new element. Do not use a damaged

properly. Reset the indicator by depressing button (A).
