3. Installation Guide
Replacing your scooter wheels requires basic tools and attention to detail. Always ensure your scooter is stable before beginning any work.
Tools Required:
- Allen wrenches (typically 5mm or 6mm, check your scooter's hardware)
- Optional: Lubricant for axles, clean cloth
Step-by-Step Installation:
- Prepare the Scooter: Place your scooter upside down or on its side on a stable surface to easily access the wheels.
- Remove Old Wheels:
- Locate the axle bolts on both sides of the wheel.
- Using two Allen wrenches (one on each side), loosen and remove the axle bolt. Keep all washers and spacers in order.
- Carefully slide the old wheel off the axle.
- Inspect Axle and Spacers: Clean the axle and inspect any spacers for wear or damage. Replace if necessary.
- Install New Wheels:
- Slide the new Z-FIRST wheel onto the axle, ensuring any spacers are correctly positioned between the wheel and the fork/deck.
- Insert the axle bolt through the wheel and fork/deck.
- Tighten the axle bolt using both Allen wrenches. Do not overtighten; the wheel should spin freely without wobble.
- Test the Wheels: Spin each new wheel by hand to ensure it rotates smoothly and freely. Check for any rubbing or excessive play.

4. Usage Guidelines
Once installed, your new Z-FIRST wheels are ready for use. Follow these guidelines for optimal performance and safety:
- Initial Ride: Take a short, controlled ride to get accustomed to the feel of the new wheels.
- Surface Awareness: While 88A SHR PU offers good grip, always be mindful of riding surfaces, especially wet or uneven terrain.
- Regular Checks: Periodically check that axle bolts are tight and wheels spin freely. Loose bolts can be dangerous.
- Avoid Extreme Conditions: Prolonged exposure to extreme heat, cold, or moisture can affect wheel and bearing performance.
5. Maintenance and Care
Proper maintenance will extend the life of your Z-FIRST scooter wheels and bearings.
- Clean Wheels: Wipe down the wheels with a damp cloth to remove dirt and debris after rides.
- Bearing Care:
- Avoid riding through puddles or in heavy rain, as water can damage bearings.
- If bearings become noisy or sluggish, they may need cleaning and re-lubrication or replacement. Consult a professional if unsure.
- Check for Wear: Regularly inspect the polyurethane for flat spots, cracks, or excessive wear. Replace wheels if significant damage is observed.
- Axle Tightness: Ensure axle bolts remain securely tightened.
