Dear, My Panasonic ES4026 shaver lost a piece that makes Trimmer work, this piece is inside the trimmer, serves to activate the trimmer and fits into two brackets that vibrate to operate the trimmer. It is a square piece of plastic, and without it the trimmer can not be triggered. I'm in Brazil and the shaver is not sold here. How can I buy this little piece Tks Ricardo - rpeternella@uol.com.br
