I had no problems as I drilled about 30 holes in the first two months after purchase. It always started easily, although it needed a little adjustment to the idle when it was received.
However, a few months later, without having operated at all, stored in a warehouse with a bit of humidity, the transmission system got stuck. I opened it to repair it and saw that the gear compartment was dry of grease (there was very little inside) and the gears had fused with the bearings. Terrible oxidation.
Since there is an inlet to add grease with a grease gun, it is a good idea to fill it as soon as you receive it. I wish I had known this from the start. They skimped on 2 euros worth of grease that would have saved the machine.
