This information will allow the user to understand the principles of operation of the device, eliminate the problems that have arisen and operate it correctly. The acceleration of the air flow contributes to the transfer of fuel (gasoline) and its atomization. In it, like any carburetors, there is a process of mixing air and fuel (gasoline) for further supply to the engine cylinders. After proper adjustment, the engine must confidently gain revolutions, slightly quadruple at maximum revolutions, and when idling, the cutting tool should not rotate. The general adjustment of the highest revolutions, engine power, temperature and gas mileage depends on the left screw (H).The contact surface is erased due to the presence in gasoline abrasive particles or due to strong vibration of the motor during operation. At this time, fuel from the chamber (16) is sucked through the jets (11,12), after which it is mixed with the flowing air. Choosing an easy to manoeuvre strimmer, yet simple to operate is now a quick choice with the highly-rated FS55-R. It’s easy to operate with one hand, with the simple trigger switch on the handle, your hand will never have to leave the strimmer’s controls.

This mechanism requires special attention, because if configured incorrectly, it will either refuse to work or will work intermittently and loss of power. If dirt accumulates in the adjustment cavity, the inlet needle cannot close the hole tightly and a lot of fuel is poured into the chamber. The membrane can undergo deformation during prolonged operation of the unit and when using aggressive fuel. The fuel pump itself, the jets and the system used to control the flow of the fuel-air mixture can be built-in or installed externally. Stihl has designed the FS 55R brushcutter with the traditional grip combination; one hand at the motor, the other at the loop hold further down.The position of the throttle (9) determines the amount of air entering the carburetor chamber, as well as engine power and the number of revolutions. The lightweight frame and engine of grass trimmer will reduce the stress on your lower back whilst operating. That is, they have only 2 adjusting screws: the idle speed regulator and the fuel mixture quality regulator at high speeds.
