When using the sawtooth blade, remove the guard for the line cutter head and grass cutting blade and replace the flange guard (A) with the sawtooth blade guard (H).
Saw tooth blades (24 - 80 tooth) have a central base diametre of 20mm and therefore require the use of the appropriate size top flange to ensure a correct fit. The part number is detailed in the cutting attachment summary chart.
For assembly see figures (E7, E8, E9).

During startup, stand in a stable position. (Be careful not to twist the starter cord around your hands). Fasten the shaft to the backpack before undertaking the starting procedure, and release it afterwards. Do not pull the starter cord all the way and do not release it abruptly against the machine as this could damage it.
Startup of cold engine
F1. Stop switch (A) turned to “I” opposite the “STOP” mark.
F2. Turn the fuel enrichment lever (B) to the closed position.
F3. Pump by pressing several times on the bulb (C) until you see the fuel flow back into the tank through the tube (D). Put on the backpack. Pull the starter cord evenly, without jerks, and release it in the same way until the motor
catches. Let the motor run for a few seconds and accelerate. This will automatically return the fuel enrichment lever to its original position.
The cutting devices are now rotating.
Startup of warm engine
F1. STOP switch turned to “I” (START). Throttle trigger lever in minimum position (released).
F4. Enrichment lever (B) in original position.
F3. Repeat item F3 in the previous paragraph.
Stopping the engine
F5. Turn the stop switch (A) to “O” (STOP).
After stopping the engine the rotating parts, blade or nylon string head, keep spinning by inertia for a few seconds.
Grip the machine firmly until they stop. In case of emergency the above delay can be abbreviated by scraping the blade supporting cup parallel on the ground.

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.
All the above adjustments should be made with the cutting devices correctly installed.
When you start the machine for carburetion, non do not wear the backpack, but set it down and hold it firmly in place with one hand while you use the other to pull the starter cord. Make sure the cutting tool is in a stable, safe position.
The warranty may be invalidated due to erroneous adjustments made by personnel not belonging to authorized service centers.
