fragiles, burinage, centrage, etc.

 

La graduation ”1” de la bague représente la vitesse minimum, avec 180 rotations par minute et 1400 percussions par minute. La graduation ”5” de la bague représente la vitesse maximum, avec 360 rotations par minute et 2800 percussions par minute.

PRECAUTION:

Ne pas régler la bague pendant le fonctionnement. Cela pourrait provoquer des blessures du fait que la perceuse n’est plus tenue que d’une seule main, ce qui empêche un contrôle solide de la perceuse.
