Allows the activation of chuck rotation, performing a forced “double movement” manoeuvre.
Suitable for installation on machines with one or two levers.
Provided in a single piece, to replace only one of the two original machine levers, normally identified as the most frequently used one, while the original remaining lever remains operational only for disconnection.
Equipped with universal levelling plate where a hole must be made that corresponds to the central “neutral” position - In this way, the safety bolt on the joint enters into the hole which in turn, in case of involuntary activation, sets the lever locking.
Activation of the chuck rotation occurs by performing in sequence: movement 1° and subsequently movement 2° - Disconnection occurs by directly performing movement 2° until the introduction of the safety bolt into the locking hole.
