Husqvarna 584 27 54-01  Chain Tensioner

Adjusted using the Chain Tensioner or Screw, your chainsaw chain tension should be evaluated before and throughout use. Maintaining proper chainsaw chain tension is critical for the long-term performance of your chainsaw. A loose chain increases the risk of kickback or the saw chain being thrown off. An overly tight chain can prevent the chain from moving freely and the added friction can cause a potential fire hazard. Remember, the saw chain should only be tensioned while it is cool.
