Working Techniques; End Of Operations - Okay BF 43 Pro Mode D'emploi

machines weighing less than 7.5 kg fitted with the
cutting line head or 3 or 4-point blades;
- the double belt model must be used for machines
weighingmore than 7.5 kg fitted with the saw blade
(if permitted).
• Single belt "MONO" models
The belt (1) must go over the right shoulder towards the
right hip.
• Double belt models
The belt (2) must be worn with:
- the machine's support and snap-hook coupling on the
right side (2.1);
- the release in front (2.2);
- the belts cross-over on the operator's back (2.3);
- the buckle properly fastened on the left side (2.4).
The belts must be tensioned so that the load is evenly
distributed on the shoulders.
USING THE MACHINE
WARNING! When working, the machine must
always be firmly held in both hands, keeping the
power unit on the right of the body and the cutting
group below the line of the belt.
WARNING! Stop the engine immediately if the
blade stops during sawing. Always beware of a kick-
back, which could occur if a blade encounters a solid
object (logs, roots, branches, stones, etc.). Do not
touch the ground with the blade. Kickbacks cause
blade recoils that are difficult to control, so as to cau-
se loss of control of the machine, compromise ope-
rator safety and cause damage to the machine itself.
Before tackling a mowing job for the first time it is advisa-
ble to gain the necessary familiarity with the machine and
themost suitable cutting techniques, finding out how to
wear the webbing correctly, firmly gripping the machine
and making the movements required by the job.
• Choosing the cutting device
Choose the most suitable cutting device for the job to be
done, according to these general indications:
- the 3-point blade is suitable for cutting brushwood
and small shrubs up to 2 cm in diameter;
- the cutting line head can eliminate tall grass and
non-woody vegetation near fences, walls, foundations,
pavements, around trees, etc. or to completely clean a
particular area of the garden;

WORKING TECHNIQUES

a) 3-point blade (Fig. 11)
Start cutting above the undergrowth and thenmove down
with the scything blade so as to cut the brush into small
pieces.
b) Cutting line head
WARNING! Use ONLY nylon lines. The use of
metal lines, plasticised metal lines and/or lines not
suitable for the head can cause serious injuries and
wounds.
During use it is advisable to stop the engine periodically
and remove the weeds wound round the machine, so
as to prevent the drive tube fromoverheating due to the
grass caught under the guard. Remove the caught-up
grass with a screwdriver to allow the rod to be properly
cooled.
WARNING! Do not use the machine for sweeping,
tilting the cutting line head. The power of the engine
could throw objects and small stones 15metres or-
more, causing damage and injuries to people.
• Cutting in motion (Scything) (Fig. 12)
Proceed at a regular pace, with a circular motion similar
to a traditional scythe, without tilting the cutting line head
during the operation.
First try cutting at the right height in a small area, so as to
then achieve a uniformcutting height keeping the cutting
line head at a constant distance fromthe ground.
For heavier cutting it can be useful to tilt the cutting line
head by about 30°.
WARNING! Do not work in this way if there is the
possibility of causing objects to be thrown, which
could harmpeople and animals and cause damage.
• Precision cutting (Trimming)
Keep the machine slightly tilted so that the lower part of
the cutting line head does not touch the ground and the
cutting line is at the required point, always keeping the
cutting device at a distance from the operator.
• Cutting near fences/foundations (Fig. 13)
Slowly approach the cutting line head to fences, posts,
rocks, walls, etc. without hitting them hard. If the line
strikes a solid object it could break or become worn; if it
gets tangled in a fence it could break abruptly.
In any case, cutting around pavements, foundations,
walls, etc. can cause greater wear than normal in the line.
• Cutting round trees (Fig. 14)
Walk round the tree from left to right, approaching the
trunks slowly so as not to strike the tree with the line and
keeping the cutting line head tilted forward slightly.
Remember that the nylon line could lop or damage small
shrubs and that the impact of the nylon line against the
trunk of bushes or trees with soft bark could seriously
damage the plant.
• Adjusting line length when working (Fig. 15)
This machine is fitted with a "Tap & Go" head.
To release more line, tap the cutting line head against the
round with the engine at top speed: the line will be relea-
sed automatically and the knife cut off the excess length.

END OF OPERATIONS

When you have finished your work:
- Switch off the engine as indicated above (Chap. 6).
- Wait for the cutting device to stop and fit the blade
guard.
