Inching mode: turn the switch to non-continuous. Press the two-hand button and the press will start. Press once, the button will incline. Keep pressing the button and the button will complete a full stroke.

Single mode: Make sure the press rod stops at the top dead center (the crankshaft clock or light clock is at 12 o'clock). The operator can operate the press with the two-hand button or the foot pedal. There is a switch on the panel to select foot control or hand control.

Continuous: First turn the switch to continuous. Keep pressing the two-hand button until the crankshaft clock light passes 135 degrees (2-3 seconds). The press starts to run automatically and continuously. Press the emergency stop button or the continuous stop button to stop the press. Slider adjustment: Inch the press rod 360 degrees or 180 degrees (the connecting rod is vertical). Turn the slider adjustment switch to up or down, press the slider adjustment button, the ball screw works, and the slider rises or falls step by step. The above method can also be used for C-type power presses, connecting rod transmission power presses, industrial power presses, etc.
