Adjusting movable and fixed knife
①
As in Figure 55, adjust the position of the fixed
knife
③
so that the fixed knife right side edge
②
matches the movable knife inner side edge
①
.
②
The initial assembling position of the movable
knife
④
is where the movable knife-edge
protrudes about 3 mm from the edge of the fixed
blade. Make sure to check the
“

movable knife initial position

on page 29.
③
The surface adhesion conditions
⑤
of fixed blade
edge and movable knife upper side have huge
impact on its trimming capacity. Please note the
various cases of movable/fixed knife surface
adhesion conditions on the picture.
(Correcting the adhesive conditions of movable
and fixed knives)
※
As in Figure 55, operate manual trimming
movement with color ink on the movable knife-
edge. By checking the ink trace remaining on the
movable knife, the surface adhesion condition of
the movable/fixed knives can be tested.
※
If the surface adhesion is not very good (same method is used to adjust the tension of movable/fixed knives),
please use the following methods: adjusting the amount and position of the washer
⑦
in the lower side of the
movable knife base
⑥
, horizontally adjusting the assembling position of movable knife shaft collar
⑧
, and
correcting the shape of fixed blade
⑨
setting position.
