Electronic Management System
EMS automatically monitors engine speed and fluctuation. When working conditions change, the micro processor in the ignition coil sends an electric signal to the carburetor to optimise the engine speed. In order to ensure optimum cutting performance, EMS automatically controls fuel supply by repeating full throttle and idle operation when needed.
Ergonomic
Small, lightweight design alongside a powerful engine for a superb power to weight ratio.
