STARTING AND STOPPING THE ENGINE

 

5.Once the engine has warmed up (The engine runs evenly when the accelerator lever is moved away from the “CHOKE” position [A]), set the throttle lever to “FAST” position [B].

NOTE: To adjust the engine speed when the mower is running, the throttle lever can be set any- where between the “FAST” [B] and “SLOW” [C] positions. However, the best results are obtained in the “FAST” position [B].

The engine may stall if the lever is in the “SLOW” position [C] when the blade clutch is engaged. To facilitate starting, place the mower on a flat surface where the grass is not long.

USING THE MOWER AT HIGH ALTITUDES

At high altitudes, the standard fuel/air mixture in the carburetor is much too rich: this will reduce performance and increase fuel consumption.

It is possible to improve the high altitude performance by fitting the carburetor with a smaller diameter jet and by adjusting the pilot screw. If you use your mower at an altitude of more than 1800 meters above sea level, we recommend that you have these modifications made by your approved Honda dealer.

Even with the appropriate modifications made to the carburetor, engine power will be reduced by about 3.5% for every 300 meters of altitude. However, the altitude will have a much greater effect on power if these modifications are not carried out.

CAUTION:

Running the mower at an altitude less than that for which the carburetor is adjusted may cause overheating and seriously damage the engine, due to the gas/air mixture being far too weak.

MISE EN MARCHE ET ARRÊT DU MOTEUR

 

5.Une fois que le moteur est chaud (Son fonctionnement est régulier lorsque l’on retire le starter [A]), mettre le levier de commande des gaz sur la position “RAPIDE” [B].

NOTE: Pour régler la vitesse du moteur au cours du fonctionnement de la tondeuse, le levier de commande des gaz peut être positionné n’importe où entre les positions “RAPIDE” [B] et “LENT” [C]. On obtient cependant de meilleurs résultats sur la position “RAPIDE” [B].

Le moteur peut caler si le levier est sur la position “LENT” [C], lorsque l’embrayage de lame est enclenché.

Pour faciliter le démarrage, placer la tondeuse sur une surface plane, sans herbe haute.

FONCTIONNEMENT EN HAUTE ALTITUDE

En haute altitude, le mélange standard essence/air du carburateur sera beaucoup trop riche : les performances diminueront et la consommation d’essence augmentera.

On peut améliorer les performances en haute altitude, en installant dans le carburateur un gicleur d’un plus petit diamètre et en réglant la vis de richesse. Si vous faites fonctionner votre tondeuse à une altitude supérieure à 1 800 mètres au-dessus du niveau de la mer, il est recommandé de faire exécuter ces modifications sur le carburateur par votre concessionnaire Honda agréé.

Même avec les modifications appropriées apportées au carburateur, la puissance du moteur diminuera environ de 3,5 % pour chaque tranche d’augmentation d’altitude de 300 mètres. Cependant, l’incidence de l’altitude sur la puissance se fera beaucoup plus sentir, si ces modifications n’ont pas été apportées.

PRÉCAUTION :

Faire fonctionner la tondeuse à une altitude inférieure à celle pour laquelle le carburateur a été réglé peut provoquer une surchauffe et causer de sérieux dommages au moteur, dus à un mélange beaucoup trop pauvre air/essence.
