Reliable replacement for worn bump knobs

Meet the Stens 385-825 Trimmer Bump Knob in a convenient 2-pack. This durable replacement part is designed to work with select Stihl trimmers, including the 4006-710-4000 model and common FS and FSE60 configurations. Rather than relying on worn components, you can refresh the control you depend on during yard work, with a part that feels sturdy in hand and simple to install.

Two knobs are included to support fast maintenance and a ready spare for busy seasons. The rugged construction resists weather, sun, and routine outdoor use, while the textured surface provides a confident grip even when you have gloves or damp hands.

Key benefits at a glance

  • Durable replacement part built to stand up to regular trimming tasks
  • Precise fit for Stihl FS models and FSE60, reducing play and wobble
  • Easy installation with no tools required for most setups
  • Two-pack design offers value and peace of mind for maintenance

Compatibility and real-world use

This knob set is built to fit the models named in the product title. In everyday yard work, you may notice smoother bump feed, more consistent line advancement, and less downtime looking for worn parts. While results depend on maintenance of the entire trimmer and other components, a fresh knob can help restore baseline performance in a busy outdoor routine.

Install with ease

  • Power off the trimmer and remove the existing knob
  • Align the new knob with the control shaft
  • Push until it seats and rotates freely
  • Test the bump feed outdoors to confirm proper operation
