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).
