5. Assembly procedures
5.1 Installing the nozzle
(1) Please remove the two screws that secure the face cover the eye guard.
(2) The tip of the Fig.No.201 nozzle is in the oblique outlet air. Is a beautiful circular mounting side of
the nozzle. Please insert 4mm or more Fig.No.109 tubes to the mounting side.
(3) Please set the nozzle where the tube is inserted into the nozzle as shown in Figure 1 to come to the
center of the Fig.No.102 holder.
(4) The equipment that will be mounted in the holder, the eye guard to face plate as shown in Figure 2,
please fix it with the Fig.No.103 screw. In this case, please adjust the air outlet of the nozzle is
facing to the needle tip.
5.2Installingthevalve
(1) Of the screw that holds the top cover
as shown in Figure 3, remove the
two front side.
(2) Throw it to the Fig.No.105 collar of
the screw hole is removed.
(3) Please fix with a Fig.No.108 screw
the valve assembly as shown in
Figure 2.
(4) Please to Fig.No.106 speed
controller Connect the air tube that
is inserted into the nozzle.
★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.

5.3Installingthepneumatic pressurecontrolrelatedparts andpiping(inthecaseof MP-G10-NC)
(1) Please fix with two wood screws provided the pneumatic pressure control unit of sewing machine
table underside as shown in Figure 4.
(2) 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.
(3) Connect to finger valve and the A port of the solenoid valve mounted in the air tube as shown in
Figure 5. Put the Fig.No.208 plug to the B port of the solenoid valve.
(4) Secure the sewing machine left as shown in Figure 6 with Fig.No.302 nylon clips air tube.
5.4Installingthepneumatic pressurecontrolrelated partsandpiping(inthe caseof MP-G20-NC)
(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 cover of the sewing machine body left side, remove the packing and C blanking plate D
from the solenoid valve as shown in Figure 7, install the solenoid valve attached. At this time,
attach the packing included with this in order to prevent air leakage.
(3) Connect to finger valve and the A port of the solenoid valve mounted in the air tube as shown in
Figure 5. Put the Fig.No.208 plug to the B port of the solenoid valve.
(4) Secure the sewing machine left as shown in Figure 8 with Fig.No.310 nylon clips air tube.

6. Operation
(1) Pull up on the handle of the filter regulator, adjust to 0.4MPa(4kgf/cm2) air pressure by turning in a
clockwise direction.
(2) Needle Cooler will work on the sewing machine rotation.
(3) Can adjust the flow rate by the speed controller of the finger valve.
(4) So that it is possible to effectively cool the needle, please adjust the direction of the nozzle.
Assembly of this device is completed, please check your work once again.
Because there is a case to unexpected behavior, please away from the sewing machine when
