C) Fixing the position of the trimmer solenoid (see figure 43)
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 (see figure 44)

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 27° to the left from the perpendicular line drawn to its center④. To make sure that this position is
maintained, adjust the length of the ball joint linking bar⑥, and tightly fasten the fixing screw② of the crank (right).
(For the adjustment of the ball joint linking bar⑥, turn the linking bar⑥ after loosening the nuts (left)⑦ and (right)⑧.
Nut (left) is left screw and nut (right) is right screw.)
C) Then, loosen the fixing screw ⑨ of the movable knife shaft crank (left), and in the same angle as the crank(right)'s③
lower assembling angle ⒔, place the crank(left) ⑩. Unfasten the fixing bolt ⑫ and hinge screw⑬ to adjust the length
of the connecting rod ⑭, and then fasten the fixing bolt ⑬ and hinge screw⑫ to make sure this position holds.
D) When the linking device is connected as such, the movement angles ⑮⒃⒔⒕ of crank (left)⑩ and (right)③ during
trimming movement results in an equal angle movements for left and right, against the perpendicular lines⑤ and ⒖
that are drawn from the center line ④ of both sides of the movable knife shafts. Hence, it can be said that the
trimming movement is very light.
E) For KM-857-7, refer only up to the assembling direction down to the movable knife shaft crank (right)③.
