Powerful 58cc / 2400W 2-Stroke Engine: Generates high torque and rapid chain speeds to power through dense hardwoods, thick tree trunks, and large logs without stalling.
Extended 22-Inch Guide Bar & Chain: Wide cutting radius allows deep bucking, felling, and efficient sectioning of wide-diameter timber in fewer passes.
Inertia Safety Chain Brake: Rapid-acting front hand guard stops the rotating saw chain within milliseconds in the event of unexpected kickback.
Ergonomic Anti-Vibration System: Multi-point dampening mounts isolate engine vibration from the front and rear handles to minimize user fatigue during extended cutting sessions.
Automatic Bar & Chain Lubrication: Delivers a constant supply of oil to the bar groove and drive links, reducing friction wear and extending chain life across projects in Nepal.
