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.
Unnecessary removal of the filter increases the risk of
injecting dust and other impurities into the engine.
When service is required, first clean the outside of the filter
housing, then 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
element and never use an incorrect element.
3. Assemble the new element and make sure it seats
properly. Reset the indicator by depressing button (A).
