Open the left and right cowling doors.
Pull down on the blade at the top, between the wheels, pulling the idler wheel toward the center.
Note:
If the blade was broken, manually push the idler wheel back toward the center of the cowling.
When the blade is loose enough to be removed, pull it off the wheels and out of the guides.
Put the new blade over the wheels and through the guides with the teeth facing forward and
pointing toward the pull wheel, or in the direction of the dust chute.
Align blade to the wheels.
