Inspect the air cleaner/filter at the
scheduled maintenance intervals.
See
. If you are driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
To inspect the engine air cleaner/
filter, remove the filter from the
vehicle and lightly shake the filter to
release loose dust and dirt. If the
filter remains covered with dirt, a
new filter is required.
To inspect or replace the air cleaner/
filter:
1. Remove the two screws, tilt the
cover, and slide it out of the
assembly.
2. Inspect or replace the engine air
cleaner/filter.
3. Lower the cover, slide it into the
assembly, then secure with the
two screws.
See
for replacement intervals.
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.
The cooling system allows the
engine to maintain the correct
working temperature.
