After every use
In order to avoid overheating the motor, remove any dust and dirt from the slots on the cylinder cover and finds of the cylinder using a wooden scraper. Clean the backpack (if you wish, you can wash the padding after removing it from the frame). Store the machine in a dry place.
After 25 hours of use
Remove the filter as shown in the figure and clean it using a gentle jet of compressed air. For more thorough cleansing, you can wash it with soapy water.
After 50 hours of use
Add some high speed gear grease in the gearbox through hole (C). Remove and clean the spark plug (set the space between the electrode at 0.5/0.6 mm). Replace if excessively encrusted. In case of excessive encrustation check the carburetor adjustment, the percentage of oil in the fuel mixture and make sure the oil is of excellent quality and suitable for
After 100 hours of use
Replace the spark plug.
Every three months
Contact your Service Center for a complete overhaul, replacement of the fuel filter and
cleaning of the parts inside the machine. This will reduce the possibility of unexpected problems and will ensure the good performance and long life of your machine.
Periods of prolonged disuse
See “Ecology”.
If you use the machine in an exceptionally dirty or dusty environment these operations should be carried out more often.
H.Replacement of nylon string
To replace the reel of string, press both the release pawls indicated by the arrows, remove the empty reel (fig. H2), unroll any string left and rewind the new string. Open the original package of string and insert the ends of the two strings in the eyelets on the reel, then wind the strings completely on the reel in the same direction and fasten the end of each string in the 2 opposite grooves. Replace the reel in its housing and thread the ends of the strings in their bushings. Pull each string so that about 15 cm comes out on each side. Reassemble the nylon string head as shown (fig. H5). If the reel becomes excessively worn, replace it with a whole new reel.

Backpack adjustment
During adjustment remember that the weight of the machine should be distributed mainly on your hips, while your shoulders serve to balance the load. Respect of these precautions will ensure a better balance and be less tiring for your back. Adjust the shoulder straps so that the belt is at hip height. Fasten the belt and adjust the straps so as to distribute the load and balance the weight of the machine accurately. Fasten the shaft to the backpack. Adjust the fastening belt so that the shaft is in the best position for starting the machine ( 12).
Cutting techniques
During the cutting operations, keep the engine running at high speed. After every cutting stage, decelerate the engine to minimum speed as running it at top speed without a load can damage the engine severely.
Wait until the engine is running at minimum speed before moving the machine from one section to another.
The machine is ideal to complete the work of the lawnmover. In fact, it can reach places where a normal lawnmower is unable to go.
Cutting and trimming grass borders with the nylon string head
Cutting with the nylon string head is suitable for light jobs like trimming borders and cutting the grass around trees.
Mowing
To prevent damage to your lawn or the cutting mechanism, keep the string parallel to the ground but avoid contact with the terrain.
Trimming borders
Angle the nylon string head keeping it a short distance from the ground. Cut using the end of the string. Do not press the string against the material to be cut.
