Apparaat prima. Olie en benzine erin, starten en lopen.
Zeer lange levertijd. Twee maanden wachten en daarna nog twee maanden. Tot bleek dat er ergens nog een stond.
Communicatie slecht.

Livraison ok, mais impossible d'ouvrir le couvercle de côté pour mettre de l'huile.
Il a fallu un long (30cm) tournevis plat pour déboîter les attaches intérieures.
Le problème était causé par l'attache supérieure cassée à l'usine lors de la fermeture du couvercle. J'ai des photos à votre disposition.
Sinon la machine fonctionne bien et correspond à mes besoins.
Merci de me répondre sur ce problème.

Frequently Asked Questions

The most effective way is to enable Economy Mode on the control panel. This function automatically regulates the engine speed: as soon as consumption decreases, the inverter instantly reduces the speed to a minimum. This provides two main advantages: fuel savings of up to 50% and a significant reduction in noise levels. Enable the "Economy" mode when basic consumers are operating (boiler, lighting, router, TV). However, be sure to turn it off before starting powerful equipment (for example, pumps or washing machines) to avoid overload protection.
