    Hi sir
    Hope you are well
    i recommend you Reset the CPU board,normally they have small Switch, in the same board.
    If does Not have , in the CPU Processor diagrams has small Pin called Reset, use small wired connected to ground and touch the Reset pin and the other side and ground.Attached is there some example.
    However you must see if there are ANY leakage in the Pneumatic system for Full RPC , test the Valve bar system if there are Voltage in terminal, and loose any Wires, Hoses, or clamp, or Spring defective..
    Test if there are some part(s) with lack of Lube
    Let me know.

    Hello Mr.

    Thank you for taking the time for us. I am very glad your answer.
    But we can't find "Reset" switch in the CPU Board. I will send you boards photo. Please mark the where "Reset" switch.

    With best regards.

    Dear Sir
    I do not see any Small switch, and battery backup.
    As i did explain I do not see the CPU(central processor Unit) Ic too, Are you sure this
    this the only Electronic boards?
    Attached example how you will see the CPU board coming in RYOBI, battery, CPU, RAM, ROM small POT for adjust or reset the CPU
    Did you do the steps in search for Leakage in the system RPC ??
    Let me know or send me to my email.
    Let me know.
