The housing that supports the controls and operating elements has a structural height sufficient to position the cutting element correctly for cutting tangentially to the ground surface, without any effort on the part of the user while mowing or freeing shoots. It is well known that spinal pathologies result from a prolonged working posture regardless of age, but with greater exposure for people over 40 who continuously use equipment suited to the complexity of the job. Therefore, the factor that significantly modulates occupational pathology is improved with the help of the Ruris Comfort System, which is focused on the posture and the mowing angle. It is well known that a working posture, whether for a short or a long time, can lead to serious spinal disorders. The RURIS RR400C premium trimmer is equipped with a 5-point Anti-Vibration System for efficient and safe use. Steel springs act as anti-vibration elements to reduce the transmission of vibrations caused by the engine and the rotating cutting element. As a result, the handle has extremely low vibration and the trimmer is easy to guide/steer. The vibration break points are correctly distributed longitudinally along the shaft tube, where the fifth point highlights the Five Breakpoint Engine Technology. The longitudinal distribution consists of: 2 vibration break points on the front part of the plastic housing located on the tube; 2 vibration break points in the middle of the plastic housing located on the tube; 1 vibration break point at the junction between the housing support and the engine, which is the critical point of vibration propagation. The reduction of vibrations transmitted by the engine at high speeds is absorbed individually and progressively, depending on the mechanical moment at which they are released at the 5 points. Vibration breaking is achieved by rubber dampers fitted longitudinally on the tube. In this way, on contact with the user's hands, vibrations are significantly reduced in the tube steering system (handles) and the control handles. In addition, the control handles of the tube are covered with rubber that absorbs the residual vibrations occasionally transmitted by the whole trimmer assembly during operation. The handle is easy to mount without tools, and the angle is easily adjusted by unscrewing the knob. It is also easy to carry and store. It is well known that vibrations and noise transmitted from one or more dependent or independent bodies have a cumulative vibration effect on the same axis or path. For this reason, the control element (handles) is built much more robustly than on a classic trimmer, so as not to allow the propagation of shock waves inside the trimmer handles and on to the user's hands.
