To inspect or replace the engine air
cleaner/filter:
1. Remove the 6 screws that
secure the cover on.
2. Lift off the cover.
3. Inspect or replace the engine air
cleaner/filter.
4. Align the filter correctly.
5. Install the cover by lowering it
over the filter and secure with
the 6 screws.
Operating the engine with the air
cleaner/filter off can cause you
or others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
