C. Fixing the position of the trimmer solenoid (ass
’
y) (See figure 44)
a) When the whole trimmer shake linkage
①
is in up position, that is, when it has come back to its original position
after finishing trimming, the distance
④
between the lower part of the roller
②
and the equal point of the trimming
cam
③
is about 0.8~1mm. Assuming that this distance
④
never changes, adjust the position of solenoid bracket
⑦
horizontally, where the solenoid housing
⑥
is attached, to make the solenoid stroke
⑤
4 mm. Then, tightly fasten
with fixing screw
⑧
.
b) After adjusting the solenoid stroke
⑤
, 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 bracket
⑦
.
(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 linkage
①
has returned to its up position after trimming action.
B. 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 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 bar
⑤
which comes assembled to trimmer shake
linkage
①
. Also, adjust the fixing screw
②
tightly.
(For the adjustment of the ball joint linking bar
⑤
, turn the linking bar
⑤
after loosening the nuts (left)
⑥
and (right)
⑦
.
⑥
is left nut and
⑦
is the right nut.)
C. Then, loosen fixing screw
⑧
of the movable knife shaft crank (left)
⑩
, and in the same angle as the crank(right)
’
s
③
lower assembling angle
⑨
, place the crank(left)
⑩
. Tightly fasten the fixing bolt
⑪
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 line
⒔
of the two movable knife shafts. Hence, it can be said that the trimming
movement is very light.
