LED Wheels Upgrade Kit: https://onefastcat.com/collections/re...

Installation Instructions:
• Use the 5.5 mm Allen wrench included in the Wheel Assembly Kit to unscrew the wheels.
• Twist counterclockwise until the bolt can pull free from the base, and slide the old rollerblade wheel off.
• Slide new wheel on the bolt with the smooth side facing outwards and the ribbed side facing in towards the base panel. Be sure to reinstall a washer on the inside of the wheel (the side facing the base panel), and then insert back into the base socket and twist clockwise until snug.

To ensure the best experience for your cat, give each wheel a test spin to make sure they spin & light up for a moment before coming to a stop. If the wheels don’t light up, try tightening them to create enough resistance to activate the lights.

Note: Store unused components for future use.
