2) Adjusting movable knife and fixed knife
a) As shown in Figure 59, move the movable knife ① and restore the position slowly. When doing so, fix the position of the
fixed knife ③ so that edge ④ of the fixed knife ③ touches the 3mm before the fixed knife trimming point ②.
b) After aligning the fixed knife ③ and the top of the movable knife ①, be sure to stick the upper side Ⓐ and bottom side Ⓑ
of the knife edge to the external side of the movable knife edge.
c) Under the above conditions, tighten the fixed knife clamp screw ⑤. Be sure that the fixed knife does not move.
d) After adjustment, move the trimmer manually once again to check the cross section of the fixed knife and the movable
knife as in the figure.
3) Final fixing of the movable knife' s initial position
※ The standard initial assembling position of the movable knife ① is where the movable knife-edge protrudes about 0.5~1mm ③
from the fixed knife edge ② when the trimming action is finished, that is, when the movable knife is in its initial stop position.
When fixing the position of the movable knife, the following directions must be followed so that the power generated in the cam ④
is delivered without any loss to the trimming action.
[Adjustment Order]
ⓐ Manually turn the pulley to finish trimming of the trimming cam ④. Place the cam so that the roller ⑥ can enter the
complementary straight line ⑤.
ⓑ Slightly loosen the fixing screws ⑦ ⑧ of movable knife shaft crank of both the left and the right.
ⓒ Press the roller ⑥ inside the cam by operating the trimmer solenoid. Push the linking bar ⑨ to the right or the left crank
linking rod ⑩ to the left so that there is no excess room in each linking device. When this is done, the roller ⑥ gets to adhere
to the right side of the cam' s complementary straight line ⑤, as can be seen in the picture ⑪. While maintaining this position,
adjust to make the movable knives on the right and the left protrude about 0.5~1mm from the fixed knife-edge. Now, tightly
fasten the crank fixing screws ⑦ ⑧ on both sides.
ⓓ If the initial position of the movable knives of both sides are to be adjusted slightly, use the ball joint linking bar ⑨. If only the
movable knives are to be adjusted, use the linking rod ⑩.
