Kickback
– When operating the Petrol Brushcutter, uncontrolled kickback may occur. – This is particularly the case when attempting to cut within a blade segment
between 12 and 2 o’clock. – Never apply the Petrol Brushcutter within a segment between 12 and 2
o’clock. – Never apply this segment of the Petrol Brushcutter blade to solids, such as
bushes and trees, etc., having a diameter in excess of 3 cm or the Petrol
Brushcutter will be deected at great force with the risk of injuries.
Kickback prevention
To avoid kickbacks, observe the following:
– Operation within a blade segment between 12 and 2 o’clock presents positive
hazards, especially when using metal cutting tools. – Cutting operations within a blade segment between 11 and 12 o’clock, and
between 2 and 5 o’clock, must only be performed by trained and experienced
operators, and then only at their own risk.
Easy cutting with almost no kickback is possible within a blade segment
between 8 and 11 o’clock.
Cutting Tools
Employ only the correct cutting tool for the job in hand.

BEFORE START OF OPERATION
Inspection and rell of engine oil
– Perform the following procedure, with the engine cooled down. – Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit
marks of the oil pipe (Fig. 2).
– Top up with oil to upper limit mark if oil is insufcient (oil level is close to lower limit mark) (Fig. 3).
– The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap.
However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of
oil pipe.
– For reference, the oil rell time is about 10h (10 times or 10 tanks of oil rell).
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 20)
Recommended oil: SAE 10W-30 oil of API Classication, Class SF or higher (4-stroke engine for automobile) Oil volume: Approx. 0.08L
Note: If the engine is not kept upright, oil may go into around the engine, and may be relled excessively.
If the oil is lled above the limit, the oil may be contaminated or may catch re with white smoke.
Point 1 in Replacement of oil: “Oil gauge”
– Remove dust or dirt near the oil rell port, and detach the oil gauge.
– Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil gauge may cause irregular oil
circulation or wear on the engine parts, which will result in troubles.

The area between the external upper and lower limits is transparent, so oil level can be checked externally against these marks.
(2) Fill with oil to upper limit mark. (see Fig. 3)
Use oil bottle when lling.
(3) Securely tighten the oil cap. Insufcient tightening may cause oil leakage.
14
Note
● Do not replace oil with the engine in a tilted position.
● Filling with oil while engine is tilted leads to overlling which causes oil contamination and/or white smoke.
Point 2 in Replacement of oil: “If oil spills out”
– If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will
contaminate the engine. Be sure to wipe out spilt oil before start of operation.
REFUELING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufciently
ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still irritated, consult your doctor.
Storage period of fuel
Fuel should be used up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade. If a special container is not used or if the container is not covered, fuel may deteriorate in one day.
STORAGE OF MACHINE AND REFILL TANK
– Keep the machine and tank at a cool place free from direct sunshine. – Never keep the fuel in the cabin or trunk.
Fuel
The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).
Points for fuel
– Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles. – Use of deteriorated oil will cause irregular startup.
Refueling WARNING: INFLAMMABLES STRICTLY PROHIBITED
Gasoline used: Automobile gasoline (unleaded gasoline)
– Loosen the tank cap a little so that there will be no difference in atmospheric
pressure. – Detach the tank cap, and refuel, discharging air by tilting the fuel tank so
that the refuel port will be oriented upward. (Never rell fuel full to the oil rell
port.) – Wipe well the periphery of the tank cap to prevent foreign matter from
entering into the fuel tank. – After refueling, securely tighten the tank cap.
● If there is any aw or damage on the tank cap, replace it.
● The tank cap is consumable, and therefore should be renewed every two to
three years.

NOTE: To increase the service life of the cutter blade it may be turned over
once, until both cutting edges have become blunt.
NYLON CUTTING HEAD
The nylon cutting head is a dual string trimmer head capable of both automatic and bump & feed mechanisms. The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing or decreasing
rpms. However, to cut soft grass more efciently, bump the nylon cutting head
against the ground to feed out extra cord as indicated under operation section.
Operation
– Increase the nylon cutting head speed to approx. 6,000 min-1.
Low speed (under 4,800 min-1) is not suitable, the nylon cord will not feed out
properly at low speed. – The most effective cutting area is shown by the shaded area.
If the nylon cord does not feed out automatically proceed as follows:
1. Release the throttle lever to run the engine idle and then squeeze the
throttle lever fully. Repeat this procedure until the nylon cord feeds out to the proper length.
2. If the nylon cord is too short to feed out automatically with the above
procedure, bump the knob of the nylon cutting head against the ground to feed out the nylon cord.
3. If the nylon cord does not feed out with procedure 2, rewind/replace the
nylon cord by following the procedures described under “Replacing the nylon cord.”

A moins d’une urgence, ne laissez jamais tomber ou couler la
débroussailleuse thermique sur le sol ce qui pourrait l’endommager
gravement. – Veillez à toujours soulevez l’ensemble de l’équipement du sol lorsque vous
le déplacez. Il est très dangereux de faire trainer le réservoir d’essence : cela
risque de créer des fuites d’essence, voir un incendie.
Faire le plein d’essence
– Eteignez le moteur lors du plein d’essence, éloignez-le des ammes nues et
ne fumez pas. – Évitez tout contact entre la peau et l’essence. N’inhalez pas les vapeurs de
carburant. Portez toujours des gants de protection durant le plein d’essence.
Changez et nettoyez les vêtements de protection à intervalles réguliers.
– Veillez à ne pas renverser d’essence ou d’huile, an d’éviter toute
contamination du sol (protection environnementale). Nettoyez la
débroussailleuse thermique immédiatement si vous renversez de l’essence. – Évitez tout contact entre vos vêtements et l’essence. Si vous renversez de
l’essence sur vos vêtements, changez-en immédiatement (pour éviter que vos
vêtements ne prennent feu).
– Vériez le bouchon du réservoir à intervalles réguliers pour vous assurer qu’il
est installé en toute sécurité et ne fuit pas. – Serrez soigneusement le bouchon du réservoir d’essence. Déplacez-vous
pour démarrer le moteur (à au moins 3 mètres de l’endroit où vous avez fait le
plein).
– Ne faites jamais le plein dans une pièce connée. Les vapeurs d’essence
s’accumulent au niveau du sol (risques d’explosions). – Transportez et stockez votre essence uniquement dans des conteneurs
agréés. Assurez-vous que les enfants ne puissent pas accéder à l’essence.

Mode d’emploi
– N’utilisez la débroussailleuse thermique qu’avec une bonne visibilité et
un bon éclairage. Pendant l’hiver, soyez attentifs aux zones glissantes ou
mouillées, au verglas et à la neige (risques de glissade). Assurez-vous
toujours d’avoir une bonne stabilité. – Ne coupez jamais à une hauteur supérieure aux épaules. – Ne montez jamais sur une échelle pour utiliser la débroussailleuse thermique. – Ne grimpez jamais dans les arbres pour utiliser la débroussailleuse
thermique. – Ne travaillez jamais sur des surfaces instables. – Enlevez le sable, les pierres, les clous etc. trouvés à l’intérieur du périmètre
de travail.
Des corps étrangers peuvent endommager l’outil de coupe et causer des
chocs en retour dangereux. – Avant de commencer à couper, l’outil de coupe doit avoir atteint sa vitesse de
travail maximale.
Rebond
– Quand vous utilisez la débroussailleuse thermique, des chocs en retour
incontrôlés peuvent se produire. – Cela risque particulièrement de se produire lorsque vous tentez de couper
avec le segment de la lame compris entre 12h et 2h. – N’utilisez jamais le segment entre 12h et 2h de la débroussailleuse thermique
thermique. – N’utilisez pas de segment de la débroussailleuse thermique thermique sur
des objets solides, comme des buissons ou arbres, dont le diamètre dépasse
3 cm. Sinon, la débroussailleuse thermique thermique risque d’être déviée
avec une grande force et de causer des blessures.
Attention : Rebond

Prévention des chocs en retour
Pour éviter les chocs en retour, souvenez-vous ce qui suit :
– L’utilisation du segment de la lame situé entre 12h et 2h présente des
dangers, surtout lorsque vous utilisez des outils de coupe en métal. – Les opérations de coupe avec les segments de la lame compris entre 11h et
12h, ainsi qu’entre 2h et 5h, ne doivent être effectués que par des opérateurs
formés et expérimentés, et à leur propre risque.
Pour une coupe avec des chocs en retour très limités, utilisez le segment de
la lame compris entre 8h et 11h.
Outils de coupe
Utilisez uniquement l’outil de coupe adapté au travail.
MS-246.4 U, MS-246.4 UE, MS-246.4 C, MS-246.4 CE avec couteau, tête à l
en nylon Pour couper des matériels épais tels que de mauvaises herbes, de l’herbe haute, des taillis, des petits arbustes, du sous-bois, du fourré etc. (épaisseur max. diamètre de 2 cm). Le fauchage doit être effectué avec des mouvements de droite à gauche de la débroussailleuse thermique en demi-cercles égaux. (de la même façon que vous utilisez une faux).
Instructions d’entretien
– Avant de commencer à utiliser l’outil, vériez son état, et notamment l’outil de
coupe, les dispositifs de protection et le harnais. Examinez également avec
