⑦ Assembling the condensation solenoid
1） Temporarily secure solenoid mounting plate ❷ to the arm with M5 pan head screw, short ❸ .
2) Temporarily secure sub-assembled condensation solenoid to the arm with M6 pan head screw ⓴ and
washer, large . Then, temporarily secure the condensation solenoid to solenoid mounting plate ❷
which has been temporarily fixed in the aforementioned step 1) with M5 pan head screw, long ❹ and
washer ❺ .
3) Fix screw ⓴ so that it is brought to the top end of the slot. Then, tighten screw ❸ while pressing mounting
plate ❷ against the condensation solenoid. Then, tighten screw ❹ .
At this time, check first to make sure that the solenoid plunger is allowed to rotate in the axial direction, to
smoothly rotate and to return to its initial position by the spring. Then, securely tighten the screws.
[Tightening torque: 1.9 - 2.9 N·m (20 - 30 kgf·cm)]
4) After tightening the screws, check to make sure that relevant parts normally operate and the screws are
securely tightened.

(Caution) If the solenoid plunger fails to rotate
in the axial direction or fails to operate
smoothly, the solenoid plunger has
been assembled off-center. In this
state, operation failure and abnormal
wear can occur. Re-install the solenoid
plunger correctly.
1) Set the stitch dial to "0.5". (For the H type model,
set it to "0.75".)
2) Pull the plunger in the direction of the arrow (or
move condensation arm ❽ in the direction of the
arrow) until condensation arm ❽ comes in light
contact with the feed adjusting rod.
(Caution) Take care not to allow the feed adjustment
rod to move. If the feed adjustment rod
moves, the condensation pitch cannot be
adjusted as desired, resulting in thread
trimming failure or in longer remaining
length of thread after thread trimming.
