If the mechanism encounters excessive strain or a physical obstruction, the fork head is engineered to break first. This intentional design protects the more expensive motor and the structural frame of your chair from catastrophic damage. If your original fork head broke, and a replacement breaks shortly after installation, this strongly indicates an underlying issue causing extreme motor strain. For example, if your chair is positioned too close to a wall, the motor will strain against that immovable force and snap the fork head. Please check your chair's clearance before operating.\u003c\/p\u003e\n\u003col\u003e\n\u003cli style=\"margin-bottom: 0.5em;\"\u003e\n\u003cstrong\u003eClear Debris:\u003c\/strong\u003e Use needle-nose pliers to carefully spin out and remove any broken plastic pieces remaining down inside the stroke tube.
