Remove the small gearing cover with a
small screwdriver.
Instruction for exchanging the Gearwheel 3
Here you see the opened gearing.
As you can see, the small edge from the
release knob is hampering you by removing
the damaged gearwheel.
Cut this small edge with a very sharp knife,
so that the damaged gearwheel becomes
free.
