Using this Bruder cement mixer is easy. First, you can tilt the cab to check out the engine if you like. To start the mixing, use the hand - crank on the water tank to turn the drum. When it's time to empty the drum, just reverse its rotation and the load will move to the rear discharge chute. There are two plug - in drain chutes that you can attach as needed. A bworld figure can climb the ladders to control the mixer functions. As for maintenance, keep it clean after play. Avoid dropping it or using too much force on the moving parts. Store it in a dry place to prevent any damage. Have fun creating amazing play worlds with other BRUDER vehicles!
