Key benefits Restores full front hand guard and chain brake function for compatible chainsaws, helping the tool to its intended operating condition. Precise fit for specified models, minimizing adjustment and ensuring smooth operation after installation. Durable construction resists normal wear from repeated use and exposure to jobsite conditions. Simple swapin replacement that saves time compared with rebuilding or sourcing used parts. What it does Serves as the front hand guard and actuating lever for the chain brake assembly. When pushed forward or pulled back as intended, it activates the chain brake mechanism to stop chain rotation. Matches original mounting points and lever geometry for reliable linkage movement and consistent brake engagement. Compatibility and size Compatible with chainsaw models 029, 039, MS290, MS390, and MS310. Designed to match the original equipment dimensions for those models to provide correct clearance and lever travel. Constructed from material engineered for repetitive mechanical action and exposure to outdoor work environments. Performance and maintenance Smooth lever action for predictable brake engagement and release. Corrosionresistant finish where applicable; wipe clean after use and inspect mounting hardware during routine maintenance. the part if cracks, excessive wear, or deformation are present to maintain reliable operation. Installation Intended as a direct replacement part for the listed models. Basic tools and common mechanical skills are sufficient for removal of the old guard and installation of the replacement.

Use scenarios Household yard work: a worn or damaged front hand guard on a homeowner chainsaw used for pruning and firewood cutting. Property maintenance: Quick replacement on a chainsaw used by landscapers or caretakers to restore reliable brake lever operation between jobs. Field service by equipment technicians: Fast swapin part during routine maintenance or service calls to a chainsaw to serviceable condition. Note Verify model compatibility before by matching engine model numbers or existing part appearance. If unsure, compare the old guard to this replacement for mounting hole locations and lever shape.
