C. Fixing the position of the trimmer solenoid (ass’y) (See figure 44)
a) When the whole trimmer shake linkage① is in up position, that is, when it has come back to its original position
after finishing trimming, the distance④ between the lower part of the roller② and the equal point of the trimming
cam ③ is about 0.8~1mm. Assuming that this distance④ never changes, adjust the position of solenoid bracket⑦
horizontally, where the solenoid housing⑥ is attached, to make the solenoid stroke⑤ 4 mm. Then, tightly fasten
with fixing screw⑧.
b) After adjusting the solenoid stroke⑤, manually operate the solenoid shaft ⑨ towards the arrow direction. See
whether it returns to its original position fast and smooth when released. If not, proceed with horizontal
adjustment of the bracket⑦.
(2) Adjustment of linking device for movable knife shaft and the trimmer driving part
A. When the previously explained adjustment of trimmer driving part is complete, it is in its normal position where the
trimmer shake linkage① has returned to its up position after trimming action.
B. First, loosen the fixing screw② of the movable knife shaft (right), hold the initial assembling angle of the crank (right)
③ to be about 15°, 30’to the left from the perpendicular line ⒕ drawn to its center ⒔. To make sure that this
position is maintained, adjust the length of the ball joint linking bar⑤ which comes assembled to trimmer shake
linkage①. Also, adjust the fixing screw ② tightly.
(For the adjustment of the ball joint linking bar⑤, turn the linking bar⑤ after loosening the nuts (left)⑥ and (right)
⑦. ⑥ is left nut and ⑦ is the right nut.)
C. Then, loosen fixing screw⑧ of the movable knife shaft crank (left) ⑩, and in the same angle as the crank(right)’s ③
lower assembling angle⑨, place the crank(left)⑩. Tightly fasten the fixing bolt⑪ to make sure this position holds.
D. When the linking device is connected as such, the movement angles ⒃, ⑮, ⑭, ⑨ of crank (left)⑩ and (right)③
during trimming movement results in an equal angle movements for left and right, against the perpendicular lines ⒕
and ⒖ that are drawn from the center line⒔ of the two movable knife shafts. Hence, it can be said that the trimming
movement is very light.
