How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/filter remove the filter from
the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt,
a new filter is required.
To inspect or replace the engine air cleaner/filter,
do the following:
1. Remove the screws on the engine air cleaner/filter
and lift off the cover.
2. Remove the air cleaner/filter from the housing.
Care should be taken to dislodge as little dirt
as possible.
3. Inspect or replace the engine air cleaner/filter.
4. Reinstall the cover and tighten the screws.
{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.
