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 two-stroke
engines.
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.

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 (
).
Cutting techniques
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.
H. Routine maintenance
1 2 3 4 7 9 10
If you use the machine in an
exceptionally dirty or dusty environment
these operations should be carried out
more often.
I. Techniques for use
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.
