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.

Alles gut . Erwartung erfüllt. Abeckhaube könnte

Le site est sérieux, le produit excellent. Je conseil!!

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.
