Differences Between the D014/D015 & B132/B200
SM D-35 D014/D015/D078/D079
PTR Lift Mechanism
The PTR lift motor [A] rotates cam [B]. The rotation of the cam raises and lowers the lift plate
[C], which in turn raises and lowers the PTR [D].
This mechanism is necessary because the roller in the ITB unit that opposes the PTR is
made of a softer material than in the B132/B200. The PTR will deform this roller if it always
contacts it.
