(2) Adjustment of linking device for movable knife shaft and the trimmer driving part
When the previously explained adjustment of trimmer driving part is complete, it is in its normal position where the
trimmer shake linkage ① has returned to its up position after trimming action.
First, loosen the fixing screw ② of the movable knife shaft (right), hold the initial assembling angle of the crank
(right)③ to be about 35°to the left from the perpendicular line ⑤ drawn to its center ④. To make sure that this
position is maintained, adjust the length of the ball joint linking bar ⑥ which comes assembled to trimmer shake
linkage ①. Also, adjust the fixing screw ② tightly.
(※ For the adjustment of the ball joint linking bar ⑥, turn the linking bar ⑥ after loosening the nuts (left) ⑦ and
(right) ⑧. Then turn the linking bar ⑥.)
Then, loosen fixing screw ⑨ of the movable knife shaft crank (left), and in the same angle as the crank(right)’s ③
lower assembling angle ⑩, place the crank(left) ⑪. Loosen the fixing bolt ⑫ and the hinge screw ⑬ to adjust the
length of the linking rod ⑭. Then tighten the fixing bolt ⑫ and the hinge screw ⑬.
⑶ Adjusting movable and fixed knives
Adjusting the position of movable knife-edge and
hook
As in in the Figure, loosen the movable knife
fixing screw ③ and adjust the movable knife so
that the edge of the movable knife ① will be
positioned in the center of the V-shape groove of
the hook ②.
Then adjust the distance between the bottom of
the movable knife ① and the top of the hook ②
to be within 0.5mm. (※ After loosening the
movable knife shaft collar clamp screw ④ and
the movable knife shaft crank (right) clamp screw
⑤, adjust the movable knife shaft ⑥ vertically.
Then tighten the clamp screws ④ and ⑤.)
