The RURIS 2744e stands out for the combination of the dual 2 x 20V power supply and the brushless electric motor, which offers a cutting force comparable to that of a gasoline model, but in a cleaner and easier to maintain system. For the user, this means high working power, no twine starting, no fumes, and no additional costs generated by the classic maintenance of a combustion engine.
Another important advantage is the very high chain speed of 25 m/s, supported by the speed of 13,500 rpm. Thus, the user benefits from faster and cleaner cuts, which reduces working time and engine stress during use.
The 400 mm rail and maximum cutting length of 395 mm allow for more serious work, including cutting larger logs in one pass. For the customer, this benefit means greater versatility and the possibility of using the machine both for maintenance work and for the preparation of firewood.
The 2 speed levels and variable control via the button allow the power to be adapted according to the load. Thus, the user can save energy when cutting thin branches or using maximum power when working in harder wood material, while maintaining better control over the machine.
The SDS system for quick tensioning of the chain without tools brings real added comfort and time savings. Adjustment is quick and easy, right directly in the work area, without the need for additional accessories.
The double safety brake, low vibration, and optimized weight of 5 kg contribute to a high level of safety and comfort in operation. For the user, this means better control, increased protection, and the ability to work longer without increased discomfort.
