4.2 Installing the slide plate
(1) Refer to the part catalog P-246 for the PLK-G1010 sewing unit, and remove Fig No.B125 slide plate
(outside), Fig.No.B118, B119, B120, and B129.
(2) Temporary fix the enclosed Fig.No.142, 145, slide plate brackets L/R and Fig.No.143 mounting
plate with the bolts Fig.No.144, 146, and etc., onto the sewing machine bed. Place the Fig.No.139
slide plate and fix with the Fig.No.141 screws. Then, adjust the slide plates (inside) and (outside)
so that they are on the same plane, and fully tighten the slide plate brackets and mounting plate.
(3) Align the enclosed Fig.No.140 film sheet with the needle hole position, and attach to the slide plate
with double-faced adhesive tape, etc.
4.3 Installing the pneumatic pressure control related parts
(1) The regulator and solenoid valve assembly configured of Fig.No.301, etc., are fixed to the bottom of
the sewing machine table with the enclosed Fig.No.405 wood screws (two screws).
(2) Align the piping symbols on the branched side (φ4) of the Fig.No.307 and 308 air tubes with ports
A to D on the Fig.No.109 air cylinder, and insert the tubes.
(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) Align the air tubes (φ6) led out above with the ports A and B of the solenoid valve installed in step
(1), and insert the tubes.
(5) Bind the air tubes appropriately with the enclosed Fig.No.401 Cable ties.
4.4 Installing the pneumatic pressure control related parts
(1) Remove the cover for the connector panel on the back of the sewing machine.
(2) Disconnect the cable connected to CON13 (FU) on the solenoid PCB. This cable is not used after
this attachment is mounted. Fix it where it will not obstruct the other electric parts.
(3) Lead out the Fig.No.306 cable connected to the solenoid valve from the slot on the back of the
sewing machine table, pass through the cord bushing on the connector panel, and lead in to the
solenoid PCB side.
(4) Insert this Fig.No.306 cable connector to CON13 (FU) on the solenoid PCB from where the cable
was disconnected above.
(5) This complete the connection of the wiring. Check the connection with the following table, and then
securely install the cover removed from the connector panel.

4.5 Adjusting the home position
Due to the stitching area extension of the X axis direction, the X axis home position need to be
changed.
(1) The optimum range for moving the home position is shown as the shaded section.
(2) Move the X side detector from the standard installation position to the right side looking from the
front of the sewing machine. The positions A, B and C in the figure are the positons where the
detector is installed.
