Replacement wooden pusher.
Completely depress food into the feeding chute with the wooden pusher (but do not apply excessive force).
Don’t worry about the wooden pusher touching the twin gears; it will not harm the gears or the pusher. The pusher is made from the same high-quality wood used to make fine chopping blocks. Any accidental particles of cellulose scraped off from contact with the twin gears are non-toxic and will harmlessly pass through with the pulp.
