Using this Hape Gearhead Stunt Garage is easy and fun. First, take the two free - wheeling cars included in the set. You can place them in the boxcar elevator and turn the knob to move them to different levels of the high - rise parking lot. If you want to have a race, send the cars down the spiral ramp and time how long it takes for them to reach the bottom. You can also use the 360° loop track, which can be changed into a launch ramp for some exciting stunts. At the service center, use the turning knob to select different services and pretend to charge your cars at the charging ports. When using the toy, make sure kids play in a safe area to avoid the cars getting lost or damaged. To keep the garage in good condition, wipe it with a dry cloth regularly. Don't use any harsh chemicals as the garage is made of wood and has non - toxic details. With proper care, this toy can last for many years and provide endless fun for your child.
