    Sometimes this lever gets stuck in the middle of the 2 sensors and it interrupts the cutting. we have to pull lever and trigger the bottom sensor to continue cutting.

    Hi sir;

    Please review this steps;

    1) Please check the sensors switch(proximity swtich) , must be in 0.8mms(distance switch cylinder vs sensor switch proximity)

    2)Test if there are +24Vdc exactly in the terminal plug 44, CU9.4+CU9.5, and tigh very well the wires, or dirty sensors, or faulty.

    3) Test connection flat wire hardness IAR-AR, and exchange if necessary.

    4)Adjust the limit switch in the gear box, look for loose wires, dirty contacts, or faulty, replace, and adjust as exactly you can . Turn OFF the machine.

    Turn knife carrier down manually, until the mark 1 of the positive cam switch cam correspond with the mark 2 on the gear box, carefully thear Snap action switch!

    Hi, my experience of these arms is lack of lubrication means arm is tight. Or bracket holding solonoid has cracked causing solonoid to drop so arm doesn't pull properly. Please check
