2. Setup

2.1 Unpacking and Inspection

Carefully unpack all components. Inspect for any shipping damage. Report any damage to the carrier immediately.

2.2 Assembly

While the wheel balancer requires minimal assembly, ensure all components are securely fastened. The tire changer requires assembly of its various arms and components. Refer to the included assembly diagrams for detailed steps.

2.3 Power and Air Connections

• KT-T900 Tire Changer: Connect to a 110V / 1PH / 60HZ power supply. Connect to an air compressor providing 0.8-1.0Mpa (116-145psi) air pressure.
• KT-B750 Wheel Balancer: Connect to a 120V 1PH power supply.
• Ensure all air hoses are securely connected and free of leaks. It is recommended to replace standard hose clamps with more robust alternatives if necessary to prevent leaks under pressure.

2.4 Placement and Securing

Position both machines on a level, stable surface. For optimal performance and safety, the KT-B750 Wheel Balancer should be bolted to the floor to prevent movement and ensure accurate measurements during operation.

3. Operating Instructions - KATOOL KT-T900 Tire Changer

The KT-T900 is designed for efficient and safe tire changing with its automatic hydraulic system.

3.1 Mounting and Demounting Tires

1. Positioning the Wheel: Place the wheel onto the turntable. The wheel clamp can accommodate sizes from 12" to 30".
2. Clamping the Wheel: Use the foot pedals to activate the rim clamps, securing the wheel firmly to the turntable.
3. Bead Breaking: Utilize the bead breaker arm to separate the tire beads from the rim. The hydraulic system ensures powerful and controlled operation.
4. Mounting/Demounting Head: Position the stainless steel mounting head (with plastic cover to protect rims) at the edge of the tire. The leverless design simplifies the process.
5. Using the Assist Arm: For difficult tires, such as run-flat or low-profile, engage the built-in top assist arm to help hold the tire bead in place.
6. Rotation: Use the foot pedal to rotate the turntable, allowing the mounting head to smoothly remove or install the tire.
7. Inflation (Bead Blaster): For stubborn beads, the integrated bead blaster can be used to quickly seat the tire. Ensure proper safety precautions are followed.

4. Operating Instructions - KATOOL KT-B750 Wheel Balancer

The KT-B750 provides precise wheel balancing with its automatic measurement ruler and various balancing modes.

4.1 Mounting the Wheel

1. Ensure the balancer is powered on.
2. Mount the wheel securely onto the balancer's shaft. Use appropriate cones and a quick-release nut to center and hold the wheel.

4.2 Inputting Wheel Dimensions

1. Use the automatic measurement ruler to input the 'A' (distance from machine to rim) and 'D' (rim diameter) values. The ruler will automatically detect and display these values on the control panel.
2. Manually input the 'W' (wheel width) value using the control panel buttons.
3. Select the desired balancing mode (e.g., Dynamic for clip-on weights on both sides, Static for single-plane balancing) using the control panel.

4.3 Balancing Process

1. Close the wheel guard (if equipped) and press the START button. The machine will spin the wheel to measure imbalance.
2. The display will show the required weight amounts and their positions (indicated by the laser pointer).
3. Apply the indicated weights to the inner and/or outer edges of the rim as directed.
4. Spin the wheel again to verify the balance. Repeat the process if necessary until the display shows zero or minimal imbalance.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your KATOOL equipment.

5.1 General Cleaning

• Keep both machines clean and free of dirt, dust, and tire debris.
• Wipe down surfaces with a damp cloth. Avoid using harsh chemicals that may damage finishes or electronic components.

5.2 Lubrication

• Tire Changer: Periodically lubricate moving parts, such as the assist arm joints and clamping mechanisms, according to the manufacturer's recommendations.
• Air System: Ensure the air filter/regulator unit (if present) is regularly oiled. The instruction label on the unit advises frequent oiling to the oil cup and to release water.

5.3 Air System Inspection

• Regularly check all air hoses and connections for leaks. Replace any worn or damaged hoses and ensure clamps are secure.
• Monitor the air pressure gauge to ensure it operates within the specified range.

6. Troubleshooting

This section addresses common issues you might encounter.

6.1 Tire Changer Issues

• Difficulty with Bead Breaking/Mounting: Ensure proper lubrication of tire beads. Verify adequate air pressure to the machine. Utilize the assist arm for low-profile or stiff tires.
• Air Leaks: Inspect all pneumatic connections, especially hose clamps. Replace any damaged hoses or fittings.

6.2 Wheel Balancer Issues

• Inaccurate Readings: Ensure the machine is bolted securely to a level floor. Verify correct input of wheel dimensions (A, D, W). Perform the self-calibration program if readings are consistently off.
• Machine Not Starting: Check power connections and ensure the power switch is on.
