BEFORE STARTING THE ENGINE

1. Checking and Refilling Engine Oil

1)Perform the following procedure, with the engine cooled down. Otherwise skin burn may result.

●Inspection: Put the blower on a flat surface and remove the oil cap.

Check the oil gauge (1). Make sure that the oil level is within the upper (2) and lower (3) limit marks. If the oil is not up to the 100 ml level (4), fill up with new oil.

●Filling oil: Put the blower on a flat surface and remove the oil cap.

Fill the oil up to the upper limit of the oil level gauge.

2)On average, engine oil needs to be added after every 20 hours of operation (every 10 – 15 refuellings).

3)Change the oil whenever it becomes dirty or significantly changes color. (Refer to “Replacement of engine oil” for the oil change procedure and frequency.)

(1)

(2)

(4)

(3)

Recommended oil: Dolmar genuine oil or SAE10W-30 oil of API type SF grade or better (4 stroke motor oil for automobiles) Oil capacity: Approximately 0.22 L (220 ml)

NOTE:

●If the blower is not stored in an upright position, the oil may flow from the level gauge into the engine and give a false reading when checking the oil level. This may result in inadvertently overfilling whenever adding engine oil. Always store the blower in an upright position.

●If the engine oil is exceeded, the oil may spill from the breather of the air cleaner and make surrounding parts dirty, or white smoke may appear due to burning excessive oil.

Replacement of Oil “Oil cap”

●Remove dust or dirt near the oil refill port, and detach the oil cap.

●Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or wear on the engine parts, which will result in troubles.

After refilling oil

● Wipe with a rag any spilled oil.

10

2. Fuel supply

WARNING:

●When refuelling the unit, be sure to observe the following instructions to prevent ignition or fire or personal injury:

–Fuel supply must be made in a place free of fire. Never bring the fire (smoking, etc.) near the place of fuel supply.

–Stop the engine and allow the engine to cool down before refuelling.

–Refuel on flat surface. Do not refuel on unstable or bad ventilated place.

–Refuel in good light and visibility.

–Refuel at open clear place.

–Open the fuel tank cap slowly. The fuel may be spilled out by internal pressure.

–Take care not to spill the fuel. Any spilled fuel must be wiped clean.

–Carry out fuel supply in a well-ventilated place.

●Handle the fuel with care.

–Fuel sticking to the skin or entering an eye may cause allergies or irritation. When any physical abnormality is detected, consult the medical specialist immediately.

●DO NOT put oil in the fuel tank.

STORAGE PERIOD OF FUEL

Fuel should be used within a period of 4 weeks, even if it is kept in a special container in a well-ventilated and shaded area. Otherwise, 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 a car.

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 start-up.

When refuelling, stop the engine and wait for the engine to cool down.

REFUELLING METHOD

●Loosen the tank cap a little to release the tank pressure.

●Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. DO NOT fill fuel up to the top of the tank.

●After refuelling, securely tighten the tank cap.

●If there is any flaw or damage on the tank cap, replace it.

●The tank cap wears out in course of time. Replace it every two to three years.

●DO NOT put fuel in the oil fill port.

INSPECTION AND MAINTENANCE

CAUTION:

●Before inspection and maintenance, stop the engine and allow it to cool down. Remove the spark plug and plug cap.

– Otherwise the operator may suffer burn or serious injury due to an accidental start-up.

●After inspection and maintenance, make sure that all parts are assembled. Then, proceed to operation.

1. Replacement of engine oil

Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replacement.

CAUTION:

●The engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, make sure that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald. Allow sufficient time after stopping engine for the engine oil to return to the oil tank to ensure accurate reading of the oil level indicator.

●If the oil filled above the limit, it may become dirty or may catch fire with white smoke.

Interval of replacement: After first 20 operating hours, followed by every 50 operating hours

Recommended oil: SAE10W-30 oil, API Classification SF Class or higher (4-stroke engine oil for automobile)

Oil Change Procedure

Please follow these steps when changing the oil:

(1)	Set the blower down on a level surface.		(4)
(2)	Put a waste oil container under the drainage hole (1) to catch
	the oil as it drains out. The container should have a capacity of
	at least 220 ml to be able to catch all of the oil.		(3)
(3)	Loosen the oil drain bolt (2) to let the oil drain out. Be careful not
	to allow oil to get on the fuel tank or other parts.	(2)
	CAUTION:		(1)
	● Be careful not to lose the gasket (aluminum washer) (3). Put
	the oil drain bolt (2) in a location where it will not accumulate
	dirt.
(4)	Remove the oil cap (4). (Removing the oil cap (4) allows the oil
	to drain easily.)
	CAUTION:
	● Be sure to set the oil cap (4) down in a location where it will
	not accumulate dirt.
(5)	As the level of the oil being drained decreases, tilt the blower
	over on to the side with the drain so that the oil will completely
	drain out.
(6)	After the oil has completely drained out, tighten the oil drain bolt
	(2) securely. If the bolt is not tightly fastened, this may result in
	an oil leak.
	CAUTION:
	● Do not forget to put the gasket (aluminum washer) (3) back
	on when reattaching the drain plug.
(7)	Adding oil during the oil change procedure is performed in the
	same manner as the separately explained procedure for adding
	oil whenever the level is insufficient. Always add oil by filling
	from the opening under the oil cap.
	(Specified oil level: Approximately 220 ml)
(8)	After filling with oil, tighten the oil cap (4) securely to prevent oil
	leaks.

Points in replacement of engine oil

●Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the relevant laws and regulations. For any points remaining unknown, contact Authorized Service Agent.

●Oil will deteriorate even when it is kept unused. Perform inspection and replacement at regular intervals (replace with new oil every 6 months).

AVANT DE DÉMARRER LE MOTEUR

1. Vérification du niveau d’huile moteur et ajout d’huile

1)Suivez la procédure ci-dessous. Le moteur doit être froid. Le nonrespect de cette consigne peut entraîner des brûlures cutanées.

●Vérification : Placez le souffleur par terre sur une surface plane et retirez le bouchon du réservoir d’huile.

Vérifiez le niveau d’huile (1). Assurez-vous que le niveau d’huile se trouve entre les repères supérieur

(2) et inférieur de (3) l’indicateur de niveau d’huile. Si le niveau est inférieur à 100 ml (4), ajoutez de l’huile neuve.

●Ajout d’huile : Placez le souffleur par terre sur une surface plane et retirez le bouchon du réservoir d’huile.

Remplissez avec de l’huile jusqu’au repère supérieur de l’indicateur de niveau d’huile.

2) En moyenne, le niveau d’huile moteur doit être ajusté toutes les 20 heures d’utilisation, ce qui correspond à 10 – 15 pleins de carburant.

3)Changez l’huile lorsqu’elle est sale ou lorsque sa couleur change de manière significative (Voir « Replacement de l’huile moteur » pour la procédure et la fréquence de l’opération.)

(1)

(2)

(4)

(3)

Huile recommandée : huile Dolmar ou huile SAE10W-30 de classe SF ou supérieure, selon la norme API (huile pour moteur 4 temps)

Capacité du réservoir d’huile : environ 0,22 l (220 ml)

NOTE :

●Si le souffleur n’est pas rangé verticalement, l’huile risque de passer de l’indicateur de niveau dans le moteur et donner une fausse indication de niveau lors de la vérification. Ceci peut entraîner un remplissage excessif lors de l’ajout d’huile. Rangez toujours le souffleur verticalement.

●En cas de remplissage excessif, l’huile peut jaillir du reniflard du filtre à air et encrasser les pièces voisines, ou bien la combustion du surplus d’huile risque de brûler en dégageant une fumée blanche.

Démontage/remise en place du bouchon du réservoir d’huile

●Nettoyez autour de l’orifice de remplissage avant de retirer le bouchon.

●Le bouchon démonté doit rester exempt de terre et de sable. Sinon, la terre et le sable collés au bouchon du réservoir d’huile peuvent entraîner une circulation d’huile irrégulière et une usure du moteur, et provoquer des dysfonctionnements.

Après l’ajout d’huile

● Nettoyez avec un chiffon tout déversement d’huile.
