Description
Overview:
This genuine Husqvarna Chain Brake is a safety-critical assembly for the Husqvarna 346XP chainsaw. Supplied under OEM part number 537 10 78-04 (537107804), it is built for dependable stopping performance under kickback or manual activation. The hand guard is made from tough, impact‐resistant composite in Husqvarna orange, while the internal working parts use robust steel for the brake band and spring mechanism. Together they act to halt chain rotation rapidly, helping to protect the user and the saw. Designed to match the original mounting points and operating geometry on the 346XP, it restores factory function and feel after damage or wear. Suitable for professional users and DIY owners who need a reliable, authentic replacement to keep their saw safe and ready for work.
