Abstract

L'invention porte sur une scie à chaîne et à tige qui comporte une tige (1) et une scie à chaîne (2). Un commutateur à deux fils (4), un commutateur principal de scie à chaîne (5), un moteur (6), et une fiche d'alimentation électrique de scie à chaîne (7) sont agencés dans une coque de scie à chaîne (3). La tige (1) est pourvue d'un micro-commutateur (8), d'un commutateur principal de tige (9) et d'une fiche d'alimentation électrique de tige (10). La fiche d'alimentation de scie à chaîne (7) et la fiche d'alimentation de tige (10) sont en connexion électrique avec le moteur (6) par l'intermédiaire du commutateur à deux fils (4). La connexion électrique de la fiche d'alimentation de la scie à chaîne (7) et du moteur (6) ou la connexion électrique de la fiche d'alimentation de la tige (10) et du moteur (6) peut être choisie par l'intermédiaire du commutateur à deux fils (4). La liaison de la scie à chaîne et de la tige est assurée sans tension en cas d'utilisation de la scie à chaîne. Lorsque la tige et la scie à chaîne sont combinées pour l'utilisation, la fiche d'alimentation de la scie à chaîne est assurée sans tension de façon à protéger l'opérateur de toute blessure.
