The Jonsered CS 2166 has a new, clean-running, fuel-efficient engine, optimized to output more torque over a wider rpm range. It is engineered to provide additional cutting power at lower rpm when the saw is under load. The CS 2166 also has a new, larger-diameter top handle for greater operating comfort and control. Other features include a top-mounted decompression valve, side-access chain-tension adjustment, and an easy-access snap-lock air-filter cover.
