Punch start to disassemble from the top node. To begin, remove the rubber tip, then lock washer, then the head and the spring. Following this pull out the bulb.
3
All removed parts will be folded neatly (nothing should be lost, because then it will be impossible to collect the punch). After that, take the casing tool from the gearbox between the body punch and gearbox you should see a crack (3-5 cm).
4
Remove the switch by switching it to strike by drilling. Then remove the housing from the gearbox.
