Using this Meccano Rescue Squad Set is easy. First, grab the easy - to - follow instructions and start assembling the parts. You can start with the fire truck. Make sure to connect the working wheels properly and attach the extendable ladder securely. After building a model, if you want to change it, just take it apart carefully. Be gentle with the parts to avoid breakage. When you're done playing, store the parts in a dry place to prevent rust, especially the metal parts. If any parts get dirty, you can use a soft cloth to wipe them clean. Have fun creating different first - responder vehicles with your imagination!
