    Hey guys, I started having a problem where the water form looks like it’s going on when you go set it to the plate on the operator side. It will not reach the plate. My thoughts are maybe a piston is going bad. Can anyone confirm? I would appreciate it

    Age of roller? Diameter? Too tight to oscillator? Physically removed it to verify dimension? If piston is snapping into position, it’s not likely it’s a pneumatic issue, but surely possible

    Like junker told you it can be dimensions of roller also pneumatique issue but i would add another cause it can be a bad adjustement between form roller and oscilator to tight that can not let the roller form adjust to the plate or the mechanical wear on the bearings.
    God luck
