5. Assembly procedures
5.1 Installing the upper thread holding mechanism
(1) Make a bracket for mounting the upper thread holding mechanism.
(Shows an example in Figure 2.)
★Please consult sewing machine shop for the fabrication of bracket.
The mounting of the upper thread holding mechanism, you can use the mounting holes of the wiper
mechanism, to or attached to the face cover. Attach a position that does not interfere with the holding jig
to position the sewing material, consider including the sewing pattern and workability.
(2) Remove the wiper mechanism from the machine arm. Is not only part of the wiper drive, please remove
the connection wires from the sewing machine.
★Can not be shared with the wiper mechanism and Upper Thread-Holding Device.
(3) Attach the upper thread holding mechanism to the machine arm. Please adjust the position of the upper
thread holding mechanism so that the thread distributor Fig.No.106 scoop a thread between the presser
foot and the needle, as shown in Figure 1.
5.2 Installing the pneumatic pressure control related parts and piping
Please connect the pipes so that the state of the air cylinder rod is returned when the power is turned off. If
the rod is advanced, please replace the pipe to the joint A and B of the solenoid valve after the removal of
the air pressure to stop the air.
(1) Please fix with two wood screws provided
the pneumatic pressure control unit of sewing
machine table underside as shown in Figure
3.
(2) Insert to match the symbols A and B of the
air tubes "Fig.No.207 and 208" into the ports
"Fig.No.107A and 107B" of the upper thread
holding mechanism.
(3) Pass the air tubes through the notched
section on the side of the sewing machine
unit's motor cover, and lead the tubes to the
bottom of the table from the square hole on
the table.
(4) Insert to match the symbols A and B of the
air tubes into the ports "A and B" of the
solenoid valve.
(5) Bind the air tubes appropriately with the
enclosed Fig.No.301 Cable ties.
★To work in the presence of residual pressure in the pneumatic circuit It is dangerous. Please
work after you remove the residual pressure always. The method of removing the residual
pressure, and pull up the handle of the pressure regulating filter regulator, can be done by turning
counter-clockwise until the pressure gauge shows 0.
★When installing removal of parts, please go to turn off the power before. In addition, qualified
personnel of electrical work, please be performed by wiring work.
