• H3.
Pump by pressing several times on the
bulb (C) until you see the fuel flow back into the
tank through the tube (D). Pull the starter cord.
Stopping the engine
• H5.
Turn the stop switch (A) to O (STOP).
CAUTION!
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.
CAUTION!
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 emis-
sion carburetor. We recommend that you have
any adjustment of the carburetor made exclusive-
ly by an authorized service center, which disposes
of special equipment for ensuring the best per-
formance 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 prop-
er adjustment. The correct minimum speed is
shown in the instruction manual in the paragraph
of technical data.
CAUTION!
All the above adjustments
should be made with the cutting devices
correctly installed.
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.
The warranty may be invalidated due to erro-
neous adjustments made by personnel not
belonging toauthorized service centers.
I. Carburetor adjustment
Check periodically to see that all the screws in the
machine are securely fastened in place. Replace
damaged, worn, cracked or bent blades. Always
make sure the blade or nylon string head is correct-
ly installed and the nut holding the blade is tight.
L1. Cleaning the air filter
(At least every 25 hours of work). A clogged filter
causes alteration of the carburetor adjustment,
reducing power and increasing fuel consumption,
as well as causing difficulties in startup. Open the
cover on the filter as shown in the figure by press-
ing in the point indicated by the arrow for release.
Clean the inside of the filter housing thoroughly
(fig. L2). The filter can be cleaned using gentle
jets of compressed air. For more thorough clean-
ing it can be washed in soapy water.
L3. Gearbox
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 exces-
sively 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 excel-
lent quality and suitable for two-stroke engines.
L5. Fuel filter
To clean or replace the filter, remove the cap on the
tank and take the filter out using a hook or long-
nose pliers. Periodically, every season, contact your
service center for general maintenance and clean-
ing of the inside. This will reduce the possibility of
unexpected problems and will ensure the good
performance and long life of your machine.
CAUTION!
Regularly it is important, in order
to prevent the engine from overheating, to
remove the dust and dirt from the vents, the cylin-
der cover and fins on the cylinder, using a wood-
en scraper.
CAUTION!
In case of prolonged disuse,
empty the fuel tank and run the engine until
it is out of gas. Store the brush cutter in a dry
place.
L6. Attachments maintenance (for split shaft
models only)
Follow maintenance instructions on the attach-
ment manual.
L. Routine maintenance
CAUTION!
Use only the recommended type
of nylon string. Do not use steel wires for any
reason, in order to prevent serious injury.
String replacement
If, when you bump the nylon string head on the
ground, no more string comes out, it means there is
none left and you have to replace it. To replace the
