This unit offers a practical combination of professional-grade features and user-friendly operation, making it suitable for felling medium-to-large trees or clearing storm damage. For landowners who require a machine that can handle substantial cutting diameters while remaining easy to service, this model provides the necessary strength to get through the workday with fewer interruptions.

Side-access chain tensioner allows for convenient adjustments using a bar wrench without touching the sharp chain

Tool-free fuel and oil caps feature a patented design for quick and secure sealing in outdoor environments

To maintain the longevity of the engine, the air filter should be inspected frequently and cleared of fine debris using a soft brush or compressed air. The guide bar should be flipped over every time the chain is sharpened to ensure the rails wear down at the same rate and the saw continues to cut straight. Using fresh fuel with a minimum octane rating of 89 and a high-quality synthetic oil mix will prevent carbon deposits from forming on the internal components of this high-displacement engine.
