[When to Change] The cyclone baffle bin runner helps support the dust bucket components. If you experience difficulty opening the dust bin lid via the slide rail during garbage removal, causing the bin to fall off, inspect the triangular part on the support plate of the cyclone separator. If it is missing or broken, replace it with a new bin runner for proper operation. [Easy to Replace] The bin runner comes with disassembly tools, making it easier to disassemble and replace with the help of an installation video. The entire process takes only a few minutes. Please keep your screws secure to prevent loss, as they are a special size. Replacement screws may be available in our store if needed. Upgraded and Stronger Design Features an exclusive widened stress point and an enlarged release bin switch handle design, allowing easier dustbin release and effortless emptying. The handle fits perfectly with the opening mechanism. Updated Opening Handle This version is compatible with the switch lever. Unlike older short and narrow versions, this has been upgraded for better ergonomics, improved force application, and reduced finger discomfort from repeated use. Perfect Compatibility This dustbox red lever repair accessory is a direct replacement for the trigger opening switch button on V10, SV12, V11, SV14, V12, V15, and Gen5 models.
