Using this MAN TGA Cement Mixer is a breeze. First, if you want some extra fun, you can install the optional Light and sound module in the cab. To operate the mixer drum, simply use the hand crank on the water tank. When you need to empty the drum, reverse its rotation direction. There are two extra drain chutes for more convenience. As for the driver's cab, note that the doors can't be opened, but you can adjust the folding outside mirror. When it comes to maintenance, since it's made from high - quality plastics like ABS, you can clean it with a damp cloth. Just keep it away from sharp objects to avoid scratches. And always remember, this toy is not suitable for children under 36 months because of the small parts. It's great for kids 3 years and older to play with both inside and outside the house.
