Every 50 working hours add grease for high
speed gears in the gearbox, through the hole
(C).
L4. Spark plug
Periodically (at least every 50 hours) remove
and clean the spark plug and set the space
between the electrodes (0.5/0.6 mm). Replace it
if excessively encrusted or, in any case, after
100 working hours. 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.
CAUTION! Use only the
recommended type of nylon string.
Do not use steel wires for any
reason, in order to prevent serious

replace the reel of string, press both the release
pawls indicated by the arrows, remove the empty
reel (fig. M2), unroll any string left and rewind the
new string.
M3. Rewinding 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.
