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. Lift the filter cover tabs on top of the engine air
cleaner/filter housing.
2. Push the filter cover housing toward the engine.
3. Pull out the filter.
4. Inspect or replace the engine air cleaner/filter.
See Normal Maintenance Replacement Parts
on page 6-13.
5. To reinstall the cover, position the tabs through the
slots on the housing. A notch on the sides of the
filter cover will indicate the correct engagement.
6. Push the cover tabs on top of the housing to lock
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 flame 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.
