Faster than Standard: Powered by a 58cc 2-stroke air-cooled engine, it delivers 2.2Kw of high-performance power with a wide speed range of 2800-11000rpm. Paired with an 18-inch hardened chain and an 18-inch one-piece molded guide, it achieves a rapid chain speed of 12.5 ft/s, enabling quick and effortless tree cutting. Security Assured: Its dual protection switch that requires simultaneous pressing to activate can prevent accidental startup, thereby enhancing operational safety. Additionally, the thicker and wider baffle enables emergency braking, blocks wood chip splashing, and avoids accidental chain contact, further boosting use safety. Good Heat Dissipation: Dense cooling holes and three-hole exhaust vent ensure good heat dissipation, which effectively prevents the body temperature and the internal oil temperature from getting too high, ensures that the machine won't go out even after a long period, and also prolongs the service life of the machine. Professional-grade Durability and Thoughtful Design: Constructed with high-grade plastic, nylon, and 65 Mn steel, it resists wear, deformation, and ensures long-term reliability, making it a durable choice for rigorous cutting tasks.The muffler, vibration-absorbing design and engine pressure reducing valve can effectively reduce noise and vibration, providing you with a comfortable user experience. Cost-effective Solution: With a diaphragm carburetor and automatic filtration systems, it can block dust and debris from entering the engine, reducing fuel waste. Its advanced automatic lubrication system further works to minimize friction between the guide bar and chain, thereby extending the chain lifespan., Weight: 15.101664947 Pounds, Manufacturer: Candygou
