I have a 2 year old Mclane edger and the spring washer for the cutterhead shaft keeps breaking off. They have sent me spares and I have used them already. What could be the problem. Am I putting them on wrong side out? Does it really matter which side is in or out? See attached for spring I am talking about. Mclane tech support says that should not be happening.
