The HUSQVARNA 591106040 is a genuine OEM replacement chainsaw chain designed for 10-inch guide bars. Manufactured under the H3740 designation, this chain features a 3/8 inch mini pitch and a .050 inch gauge, delivering consistent cutting performance in light-duty and top-handle chainsaw applications. Constructed from steel, it is built to OEM specifications, ensuring proper fit and tension on compatible Husqvarna saws. Licensed HVAC and outdoor power equipment technicians as well as qualified service dealers are the typical installers of OEM drive components such as this chain.

This chain is intended for use on 10-inch bar-length chainsaws that require a 3/8 inch mini pitch, .050 inch gauge chain. The H3740 designation identifies the chain series within the Husqvarna OEM lineup. It is suited for residential trimming, pruning, and light cutting tasks where a compact top-handle or consumer-grade chainsaw is the primary tool. The 591106040 is stated as compatible with the Husqvarna 525P4S chainsaw and select models that share the same bar and drive specifications.

Installation Notes

Chain replacement is performed by qualified outdoor power equipment technicians or experienced operators following the manufacturer service manual. Always power down the unit completely, remove the spark plug wire, and allow the saw to cool before handling the chain or bar. Proper chain tension must be set according to the saw manufacturer specifications — a loose chain is a safety hazard. Always wear cut-resistant gloves when handling saw chain.
