the top cover into the bottom hinges and turn the
cover down to close it.

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 the engine, which will damage it.
Always have the air cleaner/filter in place when
you are driving.
