Hold the replacement front cover by its outside edges and align the screw holes in
the front cover with the holes on the air filter door.

Caution

Align and seat the door carefully to avoid damaging the EMI-preventive gaskets
on the door. The air filter door must be closed and secured at all times to maintain
correct EMI performance.
