G. Carburetor adjustment
8 9 10 11
Your machine can be equipped with a low emis- sion carburetor. We recommend that you have any adjustment of the carburetor made exclusive- ly by an authorized service center, which disposes of special equipment for ensuring the best per- formance with the lowest emissions. To adjust the speed to the minimum, turn the screw marked (T) as shown: With the engine running and well warmed up, turn the screw (T) gently clockwise, until the engine rotates at regular speed (stead noise), without the cutting devices in motion. If
the cutting devices are moving, turn the screw (T) gently counterclockwise until you obtain the prop- er adjustment. The correct minimum speed is shown in the instruction manual in the paragraph of technical data.
All the above adjustments should be made with the cutting devices correctly installed.
The warranty may be invalidated due to erro- neous adjustments made by personnel not belonging to authorized service centers.
