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) The 0 to the air pressure by turning the pressure adjustment
knob of the filter regulator, and remove any residual pressure.
(2) Remove the packing and C blanking plate D from the
solenoid valve as shown in Figure 4, and install a solenoid
valve attached. At this time, attach the packing included with
this in order to prevent air leakage.
(3) Insert to match the symbols A and B of the air tubes
"Fig.No.203 and 204" into the ports "Fig.No.107A and 107B" of
the upper thread holding mechanism.
(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.
