High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase.
High altitude performance can be improved by specific modifications to the carburetor. If you always
operate the engine at altitudes higher than 1.500 m above sea level, have your authorized dealer
perform these carburetor modifications.
Even with suitable carburetor jetting, engine horse power will decrease approximately 3.5% for each
300 m increase in altitude. The effect of altitude on the horse power will be greater than this if no
carburetor modification is made.
CAUTION: Operation of the engine at an altitude lower than the carburetor is jetted for may
result in reduced performance, overheating, and serious engine damage caused by an
excessively lean air / fuel mixture.
Breaking-in the Engine
The engine reaches maximum power after the first 5-8 hours of activity.
During this period of breaking-in do not make the machine function idly at full throttle, to avoid
excessive functioning stress.
Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can
be cleared of excess fuel by following the warm engine starting procedure listed above. Ensure the
ON/STOP switch is in the ON position.
Starting could require pulling the starter rope handle many times depending on how badly the unit is
flooded.
Engine is Flooded
- Set the on/off switch to "OFF" (STOP).
- Engage a suitable tool in the spark plug boot.
- Pry off the spark plug boot.
- Unscrew and dry off the spark plug.
- Open the throttle wide.
- Pull the starter rope several times to clear the combustion chamber.
- Refit the spark plug and connect the spark plug boot, press it down firmly
–
reassemble the other
parts.
- Set the on/off switch to ON, the starting position.
- Set the choke lever to OPEN position
–
even if engine is cold.
- Now start the engine.
GB OPERATION AND SAFETY
WARNING: Do not use the machine unless you are able to call for help in the event of an
accident.
WARNING: Neither the operator of the machine nor anyone else may attempt to remove the
cut material while the engine is running or the cutting equipment is rotating, as this can result in
serious injury.
WARNING: Sometimes branches or grass get caught between the guard and cutting
attachment. Always stop the engine before cleaning.
WORKING WITH THE MACHINE
- After starting your machine as indicated in the preceding paragraph, accelerate and activate the
blades by pressing gently on the handlebars and by slowly swinging the machine from left to right, and
from right to left.
- For better control as you move forwards, apply more or less pressure to the handlebars.
- If the machine has a tendency to advance too quickly, press down on the handlebars for better control
and dig the jackleg into the ground so it works as a brake. - If the blades dig into the ground and the
machine does not move forwards, lift the right and left side of the handlebars alternatively.
- The height of the jackleg and the propulsion can be adjusted to determine how deep the machine
works.
- We recommend you work the land with several passes. This will produce finely ploughed land without
overloading the machine.
