How to Install a Husqvarna Chainsaw Bar Adjustment Bolt

The bar adjustment bolt on a Husqvarna chain saw is placed just beside the bar posts on the clutch side of the saw. This bolt aids in making an adjustment that moves the bar tighter or more loosely against the bar posts and sprockets. This will also either tighten or loosen the chain against the bar, so it’s a crucial part for safe operation. If the bar adjustment bolt no longer applies enough pressure to tighten the chain, it will need to be replaced and reinstalled.
