First, have you tried to pull the string alittle harder to get it to possibly recoil back? You are probably beyond this test.
What you need to understand about this marvelous system is that the cord must be wrapped when the tension is the most on the recoil mechanism.
There should be some metal dogs or clips that can be carefully bent back to reveal the works of this thing. Be careful not to break off these dogs as you will be in more trouble than your already in.
Once you get this off, first, do you have alot of patience? If not, you might just want to drop what you have and have it done fast and by a professional.
If you are patient, then procede on.
You have to hold this mechanism tightly in you hand so if it explodes on you, you will have control of the thing.
You are counter turning the mechanism to cause the rope to re wind, but in the opposite direction, which will cause the rope to coil back upon release.
You must wrap the coil all the way to the rubber holder, if not, the rope will not fully re wrap and you will have a foot or so just hanging out, while the motor is running.
Once you have it tightly wrapped, you must then insert the mechanism back on the set of gears without allowing it to explode. When set, then put everything back together and give it a try.
usually, it takes four or five times to understand what you need to do.
Now, after all of this, take it in and have it done by a professional.
