4. Operating Instructions
4.1 KT-T830 Tire Changer Operation
- Preparation: Ensure the tire changer is powered on and connected to the air supply. Lubricate the tire bead and rim edge.
- Bead Breaking: Position the wheel on the turntable. Use the bead breaker shovel and pedal control to break both the upper and lower beads from the rim.
- Clamping: Place the wheel on the turntable and use the foot pedals to clamp the rim securely from the outside (12"-22") or inside (14"-24").
- Tire Removal: Position the mounting head. Use the assist arm if necessary. Pry the tire bead over the mounting head using a tire lever while rotating the turntable via the foot pedal. Repeat for the second bead.
- Tire Installation: Lubricate the new tire's beads. Position the tire on the rim. Use the mounting head and assist arm to guide the tire onto the rim while rotating the turntable.
- Inflation: Inflate the tire using the integrated inflation gauge with pedal control. Ensure the bead seats properly. Do not overinflate.
4.2 KT-B760 Wheel Balancer Operation
Figure 5: KT-B760 Wheel Balancer featuring automatic measurement ruler for inputting A and D values.
- Mounting the Wheel: Select the appropriate cone and mount the wheel securely onto the balancer shaft. Tighten the quick-release nut.
- Inputting Data: Use the automatic measurement ruler to input the A (distance), D (diameter), and W (width) values. Select the desired balancing mode (e.g., static, dynamic, ALU modes).
- Starting Measurement: Lower the wheel guard (if equipped) and press the START button. The wheel will spin and the machine will calculate the imbalance.
- Applying Weights: The display will indicate the amount and location of weights required. Rotate the wheel to the indicated position and apply the correct weights to the inner and outer rim flanges.
- Re-check: Spin the wheel again to verify the balance. Repeat the process if necessary until the display shows zero or minimal imbalance.

- Daily: Clean the machine surfaces. Check air lines and connections for leaks.
- Weekly: Lubricate moving parts of the tire changer, especially the clamping jaws and assist arm pivots. Check the oil level in the air lubricator.
- Monthly: Inspect all electrical connections for wear or damage. Check the tightness of all bolts and fasteners. Clean the wheel balancer shaft and cones.
- Annually: Perform a self-calibration on the wheel balancer. Inspect the motor and belts for wear.
