Abstract

Per spostare la barra di guida su una motosega al fine di regolarne la tensione della catena, si applica la seguente procedura. Attraverso la barra di guida scorre un albero (19) avente un intaglio per la presa di un cacciavite nonché la forma di una ruota dentata (18) all'interno di detta barra di guida. Il foro nella barra di guida è il normale foro per un tirante. Il coperchio (11) sopra la frizione serve anch'esso per tenere la barra di guida in posizione e presenta un'apertura ovale (23) garantente l'accesso a detto albero in tutte le sue posizioni. All'interno della barra di guida, nel corpo della motopompa, vi è un'apposita cavità oblunga (16) per accogliere la porzione a ruota dentata dell'albero. Detta cavità presenta sul suo bordo inferiore la forma di una sezione dentata diritta (17) adattata a detta porzione a ruota dentata dell'albero.
