Products Application
System Restoration
Direct replacement when the original rubber buffers become hardened, cracked, or lose elasticity from age and exposure to oil/fuel. Worn buffers result in excessive vibration felt through the handles, rattling, and increased operator fatigue during extended cutting tasks. This set restores the saw's factory vibration-damping performance and helps maintain alignment of assemblies for consistent cutting control .
Preventative Maintenance
For high-hour professional saws used in demanding forestry and arborist applications, replacing AV buffers is recommended when excessive vibration is noticed or as preventative maintenance . A complete set ensures all vibration-damping points are renewed simultaneously for balanced performance.
Professional Chainsaw Restoration
For professionals and collectors restoring STIHL 044, 046, and MS440 series saws, this buffer set provides all necessary AV components. The set is also available as part of comprehensive rubber kits that include fuel lines, impulse lines, carburetor boots, and other essential rubber components .
