5. Assembly procedures
5.1 Installing the Pneumatic 2-Step Tensioner
Please assembled as shown in Figure 1 is the Pneumatic 2-Step Tensioner. Remove the existing
thread guide.
5.2Installingthe pneumatic pressure control related parts and piping ( in the case of MP-G10-AT )
(1) Please fix with two wood screws provided the pneumatic pressure control unit of sewing machine
table underside as shown in Figure 2.
(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) Insert to match the symbols A and B of the air tubes described above to the solenoid valve and the
Pneumatic 2-Step Tensioner ,as shown in Figure 2 and 3.
(4) Secure the sewing machine right air tube using the nylon clips of accessory ,as shown in Figure 3.
★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.

5.3Installingthe pneumatic pressure control related parts and piping ( in the case of MP-G20-AT )
(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 4, install the 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 to the solenoid valve and the Pneumatic 2-Step
Tensioner ,as shown in Figure 4 and 5.
(4) Secure the sewing machine left air tube using the cable ties of accessory.
5.4Installingthe pneumatic pressure control related parts and piping ( in the case of MP-G40-AT )
(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, install
the 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 to the solenoid valve and the Pneumatic 2-Step
Tensioner ,as shown in Figure 4 and 6.
(4) Secure the sewing machine right air tube using the nylon clips of accessory ,as shown in Figure 6.

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) Pneumatic 2-Step Tensioner will work with to input code "FUN1" in the pattern.
For details, refer to the clause of the technical manual “Operation Panel”.
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
the power is turned on and the air pressure.
