Applicator 209 is used when a full percussive effect from the entire surface of an applicator is desired. This full percussive effect is obtained because the face plate of the head assembly describes a circular motion imparted to it by an eccentric cam inside the head.
By screwing one leg of the percussion adaptor into the face plate, and affixing an applicator to the other, the oscillatory effect produced by the face plate is changed into a Directional-Stroking/Directional Percussion effect.
*Never use this Directional-Stroking® adaptor at speeds in excess of 35 CPS.
