Cutters Edge MULTI-Cut Fire Rescue Chainsaw features XTORQ technology; resulting in more power, less emissions and better fuel economy when compared to conventional 2-stroke engines. The large external air filter integrated with a uniquely calibrated velocity stack creates a turbo charging effect that further increases power, torque and chain speed, extending the durability of the carbide-tipped BULLET Chain and allowing the engine to run in higher ambient temperatures. A Tool-less Guard/Depth Gauge allows the operator to set and control the depth of the ventilation cut so the structural supports remain untouched, and the Tool-Less design allows the Guard/Depth Gauge to quickly be removed or re-installed. The top ported muffler in combination with a uniquely shaped deflector plate and Hand Guard deflect smoke away from the operator when making ventilation cuts, and a Full-Wrap handle allows the operator to safely cut in any position.
