a) Turn the handwheel until the control spring
engages into the detent of the shifter arm.
b) Continue turning the handwheel. The main cam
assembly starts turning and moving the
rod .
c) Check the minimal clearance by hand on the
rod when the control spring is not
engaged with shifter arm.
d) Check the rod tension when the control
spring leaves the indent of the right shifter.
The clearance must approximately be the
same. If incorrect:
e) Slightly loosen M4 screw and turn the
eccentric (clockwise - clearance decreases,
anti-clockwise - clearance increases).
f) Tighten M4 screw after adjustment and check the clearance in both positions.
