Remove the links too is very facile.N'achetez no hunting pin is unnecessary Small very fine screwdriver and a hammer used very carefully enough, leaning on a wooden board (board bread) and of course in disassembling a pump at the clasp to not be embarrassed. You risk nothing unless it really awkward. we can also put a fat to facilitate exit and entry pins Attention !!! follow the direction of the small arrows at dismantling and reassembly reverse observing the direction of outlet-and introduction pins. That's all !!!
