Safety guard extension (exclusively for use with nylon string head)
The string cutting blade housed in the plas- tic shield will cut the nylon string to opti-
mum length; a string that is too long reduces the rotation speed of the engine and interferes with cutting efficiency, as well as increasing the risk of injury.
The extension (B) should be installed only for use with the nylon string head, with the aid of the string cutter blade (L), that regulates the length of the string and thus the cutting diameter. For cor- rect assembly see the illustration on the cover and perform the following sequence of steps: Insert the extension (B) on the safety guard (A) at the reference notches (C), and fasten with the screws (D), then apply the string cutter blade (L) and fasten it with the screw (E) (Make sure the screws are tightened all the way (E) and are not loosened by the vibrations. If necessary, tighten them again).

b)Upper cap with blade centering - c) Blade with text and directional arrow facing upwards - d) Lower washer - e) Fixed mower gauge - f) Blade locking screw (length mm 16).
If you want to assemble the rotating mower gauge,proceed as illustrated: a) Flange guard - b) Upper cap with blade centering - c) Blade with text and directional arrow facing upwards - d) Lower washer - e) Spacer - f) Rotating mower gauge - g) Blade locking screw (length mm 34,5).
Assembly of sawtooth blade and blade guard

When using the sawtooth blade, remove the guard for the line cutter head and grass cut-
ting 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 there-
fore 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).
F. Starting and stopping the engine

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.
CAUTION! Grip the knob of the starter with 
one hand and hold the machine in a stable position with the other. (Take care not to wind the
starter string around your hand) and pull slowly until you encounter some resistance, then pull the cord sharply and forcefully (to start the engine when 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. Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm (C). The diaphragm need not be completely filled. Push the decompression valve (D) down if your models is fitted with one. Pull the cord until the engine starts. 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).
Enrichment lever (B) in original position.
F3. Repeat item F3 in the previous paragraph. Stopping the engine
F5. Turn the stop switch to "O" (STOP).
