When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/filter at the Maintenance II
intervals and replace it at the first oil change after
each 50,000 mile (80 000 km) interval. See Scheduled
Maintenance on page 6-4 for more information.
If you are driving in dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect or replace the engine air cleaner/filter,
do the following:
1. Unfasten the clips that hold the cover on and
remove the cover.
2. Lift out the engine air cleaner/filter.
3. Inspect or replace the air filter. See Normal
Maintenance Replacement Parts on page 6-14
to determine which filter to use.
4. Reinstall the engine air cleaner/filter cover.
Fasten the clips to hold the cover in place.
{ CAUTION:
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. If it
is not there and the engine backfires, you
could be burned. Do not drive with it off, and
be careful working on the engine with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire
can cause a damaging engine fire. And, dirt
can easily get into your engine, which will damage
it. Always have the air cleaner/filter in place
when you are driving.
