How do I remove the transport locks from the WDU28?

Before using the appliance for the first time, you must completely remove all four transport locks and keep them in a safe place. Take the hoses out of the holders, unscrew and remove all four transport brace screws, remove the mains cable from the holders and sleeves, then fit and lock the cover caps firmly in place by applying pressure to the snap-in hooks. Keep the screws and sleeves in a safe place for future transportation. (Page 15)
