Stepping on the retreat pedal, if there is an improper operation or abnormal equipment during the operation. Bringing the device back to its original state often has a big impact due to a little deviation. Therefore, when I test the front machine, I will pay attention to the details. The steps to adjust the front machine include:
1. When the front machine is adjusted. The shoe upper is put on the shoe last, and the upper surface of the toe portion is placed in the opening of the first claw, and the start switch (left foot switch) is stepped to clamp the first claw to the upper.
2. Press the start switch again and place the remaining upper faces into the openings of the second, third and fourth claws.
3. Then loosen the front machine to clamp the upper, second and fourth claws, and then support the upper to support the upper.
4. If it is not ideal, use the knee to touch the semi-retract switch to check the condition of the upper.
5. Adjust the position of the shoe last under the upper face to achieve the best condition of the upper. Or both hands move the two control handles and press the start switch again.
The 60-seat drop (or the position before the sweep to the pre-knot) will automatically complete the gang action. Or both hands move the two control handles and press the start switch again. The large seat is lowered (or the knife is swept to the pre-knot) and the device will automatically complete the gang action.
