I have two problems with the detacher... the front axle keeps popping off to the right. it just slides out as i am using it the second problem....the handle does not want to stay in the "Active" position. it keeps de-activating the tines every turn i make. it makes me look ridiculous by pushing the machine with one hand and holding the handle with the other, bent in half. is there anything i can do to fix both problems?? it's less than a year old. used maybe 4 times...total.
