Before the installation, operation, and inspection for this product, read the “FOR SAFE USE” and the technical manuals carefully. Also read the other technical manuals, “Sewing Machine Head”, “Control Unit” and “Operation Panel” describing some instructions, which are not in this manual, and use the sewing machine properly.

CAUTION: Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage. Note that CAUTION level may lead to a serious consequence according to the circumstances. Always follow the instructions of both levels because they are important to personal safety.

Precaution for sewing machine operation:

• Please do not operate the sewing machine without protective equipment such as a needle guard, an eye guard, a belt cover or the others.

• Please turn off the power switch when threading, changing a needle and a bobbin, cleaning, and lubricating.

Always make sure that the power is OFF before starting setting work.

The pneumatic type clamp device can be added to the jig eject device that comes standard on the PLK-J6040/J6040R/J6040R3. By holding down the sewing material, it can prevent the material from shifting during sewing.

CAUTION: Trouble such as operation errors could occur if the secondary pressure is set too high. Use within the range of 0.4 MPa (4 kg/cm²).

CAUTION: Always make sure that the power is OFF before starting setting work.

1. Attach the clamp device to the clamp frame with eight screws (No.109).

2. After installing the clamp device, check that it operates lightly by raising and lowering the right and left clamp frames. If the installation height of the clamp device differs from left to right, loosen the screws (No.109) before adjusting the position.

3. Attach the air cylinder assembly (right) to the clamp device with two screws (No.106). After installation, check that the air cylinder operates smoothly by raising and lowering the clamp device.

MEMO: If the air cylinder is running heavy, the air cylinder may be tilted against the vertical direction. In this case, loosen screws (No.106) and (No.105) before adjusting the tilt of the air cylinder.

4. Attach the air cylinder assembly (left) to the clamp device with two screws (No.106) in the same manner as described in the previous section.

1. Insert the U-groove portions on both sides of the clamp assembly into the clamp stud (No.121).

2. To prevent the clamp stud (No.121) from coming off, attach the set plates (No.207) on both sides of the clamp assembly with SW-PW pan screws M4X16 (No.206).

1. Remove the eight M4 truss screws from the rear of the sewing machine and remove the print circuit board box cover.

2. Attach the solenoid valve complete (No.211) to the print circuit board box with four SW-PW pan screws M4X25 (No.212).

3. Attach the wire cables of the solenoid valve complete to the No. 7 and No. 8 ports of the optional output connector. Remove the connector on the wire side, check the color of the wire (red or black) and the location of the port, and then install the wire by inserting the terminals into the connector until the position where the wire terminals are fixed. The wire (red) goes to port 7 and the wire (black) goes to port 8 based on the connector pin assignments.

4. After completing the wiring, check that the wires are securely fastened to the connectors, then attach the optional output connector to the board-side connector.

1. Remove the ø8 air tube on the air regulator side that is connected to the air inlet fitting of the existing solenoid valve.

2. Connect both ends of the ø8 air tube connected to the included T-shape connector (No.218) to the air inlet fitting of the existing solenoid valve and the air inlet fitting of the new solenoid valve (No.211), respectively.

3. Connect the ø8 air tube on the air regulator side removed in step (1) to the T-shape connector (No.218).

4. Attach the air joint assembly to the clamp frame with the safety socket bolt M4x12 (No.216) and the large washer 4 (No.217).

1. Refer to the illustrations in the manual and pipe the air tube to the clamp device. Cut the supplied ø4 and ø6 air tubes to the required length.

2. Install the speed controllers (No.219) near the solenoid valves. At this time, orient the speed controllers in the direction of the symbols shown in the manual.

3. The solenoid valve has two ports:

• Port A (Descent of the clamp): Connects to the A port of the right and left air cylinders.

• Port B (Raise of the clamp): Connects to the B port of the right and left air cylinders.

4. Use the flexible tube to route the air lines from the solenoid valve assembly to the air cylinders on the clamp device.

1. After completing the installation, wiring, and piping of the clamp device, turn on the sewing machine and make the operational settings for the clamp device. Refer to the following examples for the operation settings.

MEMO: For details, refer to [16] “Input/output setting mode” and [17] “Program mode” in the technical manual “Operation Panel”.

2. After completing the settings, check that the clamp device operates properly.

Setting example 1: To lower the clamp in conjunction with the jig eject device. (After the jig eject device is activated, the clamp is lowered after a 0.3 second delay.)

Setting example 2: To operate the jig eject device and the clamp push down separately by pedal operation.

※mark: The setting value is arbitrary.

The positional relationship is defined by several key dimensions as shown in the appendix diagram:

• Sewing Area: 300 mm x 300 mm, centered at the needle center.

• Overall Width (at front side): 324.5 mm to the outer edge of the frame, 309.5 mm to the inner edge.

• Overall Length (side view): 410 mm from the front to the back of the clamp device, including the jig eject device.

• Clamp Stroke: 30 st (max) for the vertical movement of the clamp.
