Using this Hot Wheels track set is super easy. First, set up the track with the 71cm wide loop. Then, take the included 1:64 scale Hot Wheels vehicle and place it at the slam launcher. Give it a good launch to start the action. You can then add more cars (sold separately) one by one. Try to time the launches so multiple cars can race around the loop without crashing too soon. For the battery box booster, you'll need to put in your own batteries (not included) to keep the cars moving smoothly. As for maintenance, keep the track clean from dust and small debris. You can use a soft cloth to wipe it down. When not in use, store the track and cars in a dry place to avoid any damage. Remember, the colours and decorations on the track and cars may vary, so don't be surprised if yours look a bit different from the pictures.
