Product Introduction: QS-400 Industrial-Grade Handheld Power Cutter

The QS-400 is an industrial-grade handheld power cutter engineered for the most demanding applications in construction, roadwork, and heavy demolition. It is distinguished by its exceptional power output, derived from a high-performance 118.8cc, two-stroke, single-cylinder enginethat delivers a robust 5.8 kWof rated power. This substantial engine capacity ensures superior torque and cutting speed for challenging materials like reinforced concrete, stone, and asphalt.

A critical design feature is the Enhanced High-Efficiency Cooling and Ventilation System. The engine housing is equipped with strategically widened heat dissipation holes that facilitate optimal airflow, effectively managing thermal load. This advanced system prevents overheating, enabling continuous, long-duration operation without power loss or engine shutdown, which is essential for high-productivity work sites.

Operator safety and cutting precision are paramount. The QS-400 incorporates a rotating, fully sealed protective coverwith integrated mudguards, effectively containing debris and slurry for a safer work environment. The machine is equipped with a large 400mm (16-inch) diamond saw blade, allowing for a deep 145mm maximum cutting depth. This combination of raw power and a large-diameter blade makes the QS-400 the ideal tool for deep-cut tasks requiring maximum efficiency and performance.
