When Should You Replace the Chain Tensioner Kit?

Replace the chain tensioner kit if the adjuster is stripped, seized, missing, worn, damaged, or no longer moves the guide bar properly. A failing chain tensioner can make it difficult to maintain proper chain tension and may cause poor cutting performance, chain derailment, uneven bar wear, or unsafe operation.

Using the correct OEM STIHL kit helps keep the bar and chain properly adjusted and supports reliable chainsaw operation.
