Some customers have reported that when coupling their new IZA twins together for the first time, in a small number of occasions the coupler pocket cover inside the wagon comes loose, meaning the socket can be pushed out of its housing and up into the wagon body.
At the factory both halves of the wagon were fitted with inner couplers. This ensures customers have a spare, and also “loosens” the coupler pocket, but obviously on one car needs to be removed before the twin can be joined up.
To avoid any possibility of the socket becoming dislodged you may wish to remove the bodies of both wagons before coupling. This is very simple as they just pull off with gentle pressure.
Then the coupler pocket covers can be held firmly in place with a fingertip as the model is clicked together.
If the cover does come loose, replacing the wire spring and putting the coupler pocket back in place – maybe with a tiny amount of adhesive – is straightforward. Even if the spring is lost and the coupler will not automatically self-centre it will still function.
