5. Operating Instructions
5.1 KATOOL KT-T850 Tire Changer Operation
Follow these steps for safe and effective tire changing:
- Prepare the Wheel: Remove any old balance weights and valve stem. Deflate the tire completely.
- Position the Wheel: Place the wheel on the turntable.
- Clamp the Wheel: Use the foot pedal to activate the clamps. Ensure the wheel is securely clamped. The machine supports outside clamping from 14-26 inches and inside clamping from 16-28 inches.
- Break the Bead: Position the bead breaker shovel against the tire sidewall, close to the rim. Use the foot pedal to activate the bead breaker cylinder, pushing the bead away from the rim. Repeat for both sides of the tire.
- Demount the Tire:
- Lubricate the tire beads and rim edges.
- Swing the mounting arm into position. The tilt-back design allows for easy adjustment.
- Engage the mounting head under the top bead.
- Rotate the turntable using the foot pedal to demount the top bead.
- Repeat for the bottom bead.
- Mount the Tire:
- Lubricate the new tire beads and rim edges.
- Position the bottom bead over the mounting head.
- Rotate the turntable to mount the bottom bead.
- Position the top bead over the mounting head. Use the assist arm for stiff sidewalls or low-profile tires.
- Rotate the turntable to mount the top bead.
- Bead Seating: Use the integrated bead blast seater to quickly inflate the tire and seat the beads. Ensure the tire is properly seated before full inflation.
- Inflate Tire: Inflate the tire to the manufacturer's recommended pressure.

5.2 KATOOL KT-B760 Wheel Balancer Operation
Follow these steps for accurate wheel balancing:
- Mount the Wheel: Securely mount the wheel onto the balancer's shaft using the appropriate cone and quick-release nut.
- Input Data: Use the automatic measurement ruler to input the wheel's A (distance), D (diameter), and W (width) values. The machine will automatically detect and input A and D values.
- Start Measurement: Close the wheel guard (if applicable) or press the START button to initiate the spin cycle.
- Read Results: The display will show the required weight amounts and their precise locations on both the inner and outer sides of the rim.
- Apply Weights: Attach the correct balance weights to the indicated positions on the rim.
- Re-spin (Check Balance): Spin the wheel again to verify the balance. If the display shows zero or minimal imbalance, the wheel is balanced.
- Remove Wheel: Once balanced, remove the wheel from the balancer.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your KATOOL equipment.
- Daily: Clean both machines of tire debris, dust, and grease. Inspect air lines and electrical cords for damage.
- Weekly: Lubricate all pivot points and moving parts on the tire changer (e.g., clamping jaws, bead breaker pivot, mounting arm) with appropriate grease. Check air pressure and filter/lubricator levels.
- Monthly: Inspect all bolts and fasteners for tightness. Check for wear on plastic rim protectors and replace if necessary. Calibrate the wheel balancer if accuracy issues are observed (refer to specific balancer calibration instructions, usually found in a separate technical manual).
- Annually: Have a qualified technician inspect and service both machines.
Important: Always disconnect power and air supply before performing any maintenance.
