6. Operating the ME-T450 Tire Changer
6.1. Preparing the Wheel and Tire
- Remove the valve core to fully deflate the tire.
- Apply tire lubricant to both beads of the tire.
6.2. Bead Breaking
- Position the wheel on the bead breaker arm.
- Press the bead breaker pedal to activate the bead breaker shovel, separating the tire bead from the rim.
- Repeat for both sides of the tire.
Figure 4: The bead breaker effectively separates the tire from the rim.
6.3. Mounting the Wheel on the Turntable
- Place the wheel onto the turntable, ensuring it is centered.
- Use the foot pedal to activate the clamps, securing the wheel firmly to the turntable. The clamps are adjustable to adapt to various tire sizes.
Figure 5: Adjustable clamps on the turntable secure the wheel.
Figure 6: Foot pedals provide control over turntable rotation and clamping.
6.4. Demounting the Tire
- Position the mounting head just above the rim edge.
- Use a tire lever to pry the top bead over the mounting head.
- Rotate the turntable using the foot pedal to fully demount the top bead.
- Repeat for the bottom bead.
Figure 7: The tire changer adapts to various tire sizes with adjustable clamps.
6.5. Mounting a New Tire
- Apply tire lubricant to the beads of the new tire and the rim.
- Position the bottom bead under the mounting head.
- Rotate the turntable to mount the bottom bead.
- Position the top bead under the mounting head and rotate the turntable to mount it.
6.6. Tire Inflation
- Reinstall the valve core.
- Use the integrated inflation gauge with pedal control to inflate the tire to the manufacturer's recommended pressure.
- Monitor the pressure carefully to avoid over-inflation.
7. Operating the ME-B620T Wheel Balancer
7.1. Mounting the Wheel
- Clean the wheel and tire assembly thoroughly.
- Mount the wheel onto the balancer's shaft, ensuring it is centered and securely fastened using the appropriate cones and quick-release nut.
- The φ36mm shaft thread is quenching treated for high strength.
