wing nut to take the cover off the air cleaner. After changing the filter,\
put
the cover back on and be sure the wing nut is properly tight\
ened. Be sure air cleaner lid is correctly positioned to seal out dust and contaminants that

can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove the top. After changing the filter,
snap both clips to secure the air cleaner. Be sure air cleaner lid
is correctly
positioned to seal out dust and contaminants that are harmful to your engine.
