To inspect or replace the air cleaner/
filter:
1. Remove the four screws and lift
the cover out of the assembly.

cleaner/filter.
3. Lower the cover and secure with
the four screws.

Warning
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.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
