Description
Overview:
This Anti Vibration Spring is a genuine Stihl component designed for the AV system on cut-off saws such as the TS410 and TS420. Built from high-grade spring steel with a durable finish, it helps isolate engine oscillation from the handle assembly, reducing hand and arm vibration during cutting. By stabilising the machine under load, the spring supports smoother operation, better control and consistent cutting accuracy. Regular replacement of worn AV springs helps protect surrounding parts and maintains the balance and feel of the saw. As an exact OEM match (4238 790 8301), it fits precisely into the designated mounting points and restores the designed performance of Stihl's anti-vibration system on compatible models.
Key Features:
- Genuine Stihl OEM part for assured fit and performance (4238 790 8301)
- Spring-steel construction engineered for repeated compression and long service life
- Helps reduce transmitted vibration to the operator for improved comfort
- Maintains saw stability and cutting accuracy under typical site conditions
- Direct replacement for the original spring; no modifications required
- Consistent dimensions for reliable alignment with existing mounts and hardware
- Suitable for high-duty applications and frequent start-stop cycles
- Corrosion-resistant finish to cope with dust, slurry and moisture
- Supports the integrity of the complete anti-vibration system
- Compatible across multiple Stihl cut-off saw models for simplified spares stocking
Typical Applications:
Used during scheduled maintenance or repair of Stihl cut-off saws working on construction sites, roadworks and landscaping projects. Ideal when operators notice increased handle vibration, reduced comfort or poor machine feel. Helps restore isolation performance for prolonged cutting of concrete, masonry, brick and asphalt in demanding, all-weather conditions.
