*** Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 90–95 containing no more than 10% ethanol.

BONJOUR
PRODUIT RECEPTIONNE PARFAITEMENT CONDITIONNE ET AVEC SES PERIPHERIQUES , CORRESPOND A MA DEMANDE DE SIMPLICITE D ACCES AUX ORGANES D ENTRETIENS , CA SENT LA QUALITE . MERCI , SERA TESTE CET ETE

Ainda tem pouco tempo de trabalho mas até ver é bom. Arrancou bem e está a trabalhar muito bem. Tem um pouco de ruido a mais, mas aguenta bem as cargas electricas.

Der erste Probelauf von ca. einer Stunde klappte ohne Probleme. Wurde mit Gas betrieben, nach Bedienungsanleitung alles für den Start vorbereitet und der Generator sprang sofort an. Auch ohne Bedienungsanleitung würde man gut zurechtkommen, da alle notwendigen Schritte zum Starten mit Symbolen auf dem Gerät selber abgebildet ist. Der Aufbau des Gerätesistsehr solide aufgebaut.

Super fed generator og hurtig levering. Jeg kan ikke ønske mere

Die Vertragsabwicklung sollte genau so sein. Das Gerät hat den Testlauf bestanden. Der Generator dient als Reservegerät für den Fall des Stromausfalls.
