(2) Pull two φ4 tubes <4> to the left through the bottom of the sewing machine arm.

(3) Remove the left screw of the wiper bracket <5> on the left side of the sewing machine.

(4) Pass two φ4 tubes <4> through the nylon clip. Fix the nylon clip (Fig.No.125) to the wiper bracket

<5> by using the screw removed in (3).

Note At this time, manually move the clamp adapter <6> to the front of the sewing machine.

Make sure that the clamp adapter and φ4 tubes <4> don’t touch each other and fix with the nylon clip.

(5) Pass two φ4 tubes from the right side of the motor <7>. Bundle it with the existing tubes using a

cable tie (Fig.No.127), and pipe it to the back of the sewing machine.

Note If the existing nylon clip is small, change the nylon clip (Fig.No.126).

(6) Insert the end of φ4 tube (One without a fiber unit)

completely into the right side of

the solenoid valve (Fig.No.123) installed earlier.

Note If φ4 tube is long, cut and insert

(7) In the reverse order of [2-4] [Installation of solenoid

valve] (1), turn the Filter regulator <1> handle

clockwise to adjust the air pressure to

0.4 MPa (4kgf/cm2) and push down the handle.
