I got a 2 or 3 old Shindy EB 630, it's the model with the throttle on on the bendable wand type thing on the left side.. Inside th wand there is this metal conduit stuff that allows the wand to bend, the metal on mine has broke.. I can't be the only one this has ever happened to? I need to know what is the easiest way to fix this? Will I have to order a whole new wand or just the metal part? Any help would be appreciated... Thanks alot.
