Superior Performance: The Chainsaw with 56cc 2-cycle gasoline engine that reaches a rated speed of 8500 rpm, delivers 2.5 Nm of max torque, and offers 3.1 HP, this gas chainsaw makes light work of various intricate and demanding cutting tasks. Use a 40:1 ratio of fuel to oil mix for the engine. Long-Lasting & Consistent: The chain saw features an air cleaning system that actively expels large dust and debris particles before they reach the air filter. An automatic oiler ensures the chain receives a consistent flow of lubricating oil during operation, enabling the saw to maintain peak performance for years to come. Smooth Cutting: The chainsaw is equipped with a recoil starter for easy pull start, a 22-inch bar and chain that cut through limbs fast, and a high-quality carburetor that makes it work more efficiently and save fuel.
