4.1 - ENGINE START (FIG. J)
1. Turn off the air. Move the air lever
(35) until it touches the top;
If the engine is warm or the air
temperature is too high, do not shut
off the air.
2. Press the carburetor pump (36)
several times until the pump is filled
with gasoline. Check if the fuel tube
is full. At this moment, the carburettor
has gasoline;
3. Set the ON / OFF switch (8) in the
position (I);
4. Press the safety lever (9) and the
throttle trigger (7) simultaneously.
Press the throttle trigger lockout (10)
to lock the accelerator;
5. Hold the unit with one hand and pull
the starter handle (37) with the other,
until the motor starts audibly;
6. After starting, the engine operates
at an intermediate speed, between idle
and maximum speed. If you want the
engine run at idle speed, press and
release the throttle trigger;
7. A few seconds after starting, open
the air. Move the air lever down;
When the starter handle returns
to its original position, the
user's hand and arm can be quickly
moved towards the combustion
engine.
Let the engine heat at idle speed for a
few seconds before using the tool.
4.2 - ENGINE STOP (FIG. K)
1. Release the throttle trigger (7) and
set the "ON/OFF" switch (8) to the
position "0";
2. If the throttle is locked with the
throttle trigger lockout (10), press and
release the throttle trigger. Set the "ON
/OFF" switch to the "0" position;
44
In case of imminent danger or
emergency,
stop
the
immediately. Set the "ON/OFF" switch
to the "0" position;
4.3 - ENGINE ROTATION
SPEED ADJUSTMENT (FIG. L)
After starting, the engine operates
at a middle speed between idle and
maximum speed.
Every time the device is used in the
continuous mode, with the throttle
trigger lockout (10) pressed, the engine
runs at a constant middle speed.
The adjustment of the rotational speed
of the engine is carried out through the
throttle trigger (7).
1. If the throttle trigger is not pressed,
the engine runs at idle speed;
2. With the throttle trigger fully pressed,
the engine reaches its maximum speed;
Adjust the rotating speed according to
the work to be performed. Remember
that higher the speed, the bigger
the noise and the greater the fuel
consumption.
4.4 - CUTTING DISCS (FIG. M)
To perform cutting works with this
machine it is possible to use two types
of discs: grass cutting discs and bush
cutting discs. Grass discs shall not be
used in bush cutting.
Grass cutting discs (38):
. This type of discs is used to cut all
types of tall and rough grass;
. The grass is cut in a pendular
movement (as using a scythe), where
the movement right to left is to cut, and
left to right is the returning movement.
Avoid the previous cut material during
the returning movement;
. If the disc is leaned to the left when
cutting, the grass will accumulate in a
line, which makes it easier to catch;
. Let the support base slightly touch the
engine
ground. It is used to protect the disc
from touching the ground;
Bush cutting disc (39):
. A bush cutting disc is used to cut/
shred bush, shrubs or wild vegetation
with a maximum diameter of 12mm;
. When cutting bush or shrubs, bring
the disc closer to the ground (as cutting
with a sickle) and cut throughout the
base;
. To cut wild vegetation, the thinning/
shredding must be performed from up
to bottom in layers, keeping the disc
at a level lower than the user's waist.
However, when bigger the distance
between the disc and the ground,
bigger the risk of particles projection.
For this reason, the user shall have
extra attention when performing this
way;
. Always operate in full speed to prevent
the accumulation of cut material on the
disc head;
. Avoid contact of the disc with
stationary objects (rocks, stones, tree
trunks). Otherwise, the device may
be thrown abruptly in the opposite
direction to the rotation of the disc. This
is the impulse of the disc. An impulse of
the disc can be violent and cause the
loss of control;
The impulse of the disc may occur
without notice. The probability of
occurrence is greater in work areas
where it is difficult to see the material
to be cut.
The impulse of the disc can also
occur if you try to cut small
trees, shrubs or bush with a diameter
greater than the size recommended by
the manufacturer.
Whenever the disc is not in use or
during transport, install the disc's
protection.
