Built with precision and reliability at its core, the NEWTOP Hus365 Chainsaw Parts Set ensures stable operation and consistent cutting results across all working conditions. The crankshaft and crankcase are made from 20CrMoTi alloy steel, processed through strict machining and heat-treatment procedures to guarantee strength and balance.
The high-performance cylinder and piston assembly maintain excellent compression and cooling, allowing smoother, more efficient operation even under continuous workload. The carburetor is designed for steady fuel intake and easy tuning, providing stable engine performance across temperature changes.
Complemented by a durable guide bar and German-alloy cutting chain, this parts set offers an ideal replacement solution for chainsaw manufacturers, garden machinery distributors, and outdoor power equipment dealers seeking reliable, high-quality components with proven compatibility and long-term value.
