New heavy-duty walk-behind saw combines 18HP engine power, 260mm max cutting depth, and semi-automatic operation for superior productivity on demanding job sites.

Engineered to address the rigorous demands of modern road construction, repair, and utility trenching, this robust walk-behind saw sets a new standard for performance, stability, and operator convenience in high-capacity concrete and asphalt pavement cutting.

Designed for professionals who require reliability and power, the QS Large-Diameter Cutter is built around a mobile rigid box-type frame, finished in high-visibility yellow. This construction is fundamental to its core advantage: superior stability that resists warping and vibration, ensuring consistently straight and precise cuts even under heavy loads.

Power and Performance Redefined

At the heart of the machine lies a powerful LONCIN 2V78-2 gasoline engine, delivering 13.4kW (approximately 18 HP) of reliable power. This robust engine provides the necessary torque to drive large-diameter blades (600mm or 700mm) efficiently through abrasive materials. Operators can achieve a maximum cutting depth of 260mm with the 700mm blade, facilitated by a precise mechanical hand-crank drive system for accurate depth adjustment.

Engineered for Productivity and Operator Ease

The QS cutter significantly reduces manual effort and enhances job site efficiency through its semi-automatic propulsion system. This feature allows the machine to move forward and backward automatically, enabling operators to focus on guidance and control rather than brute-force pushing. Combined with a guidance wheel for straight tracking and high-grip, multi-layer rubber walking wheels, the machine offers exceptional handling and reduced operator fatigue.

Advanced Features for Durability and a Cleaner Worksite

Understanding the challenges of dry cutting, Quansun integrates a comprehensive 50L steel water tank for dust suppression and blade cooling. More durable than plastic alternatives, this large-capacity system effectively controls dust, extends diamond blade life, and maintains a cleaner, safer work environment. Operator safety is further prioritized with a robust, integrated blade guard.
