I. Carburetor adjustment
Your machine can be equipped with a low emission carburetor. We recommend that you have any adjustment of the carburetor made exclusively by an authorized service center, which disposes of special equipment for ensuring the best performance 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 proper adjustment. The correct minimum speed is shown in the instruction manual in the paragraph of technical data. CAUTION! All the above adjustments should be made with the cutting devices correctly installed. CAUTION! Start the brush cutter in a flat place. During startup stand in a stable position. Make sure the blade or nylon string head do not touch the ground or any obstacles. The warranty may be invalidated due to erroneous adjustments made by personnel not belonging to authorized service centers.

L. Routine maintenance
Check periodically to see that all the screws in the machine are securely fastened in place. Replace damaged, worn, cracked or bent blades. Always make sure the blade or nylon string head is correctly installed and the nut holding the blade is tight. L1. Cleaning the air filter (At least every 25 hours of work). A clogged filter causes alteration of the carburetor adjustment, reducing power and increasing fuel consumption, as well as causing difficulties in startup. Open the cover on the filter as shown in 8 - ENGLISH the figure by pressing in the point indicated by the arrow for release. Clean the inside of the filter housing thoroughly (fig. L2). The filter can be cleaned using gentle jets of compressed air. For more thorough cleaning it can be washed in soapy water. L3.
