Wheel Balancer Machine Maintenance

1. Keep the balance shaft, quick lock nut, flange and other parts clean.

Otherwise, it will affect the balance accuracy and operation. The working principle of the balancer is to calculate the imbalance point of the tyre according to the centrifugal force. The balance shaft, quick lock nut, balance cone and other parts are directly involved in the process. If the tyre shop environment is dirty, the balance shaft, cone and other parts are covered in oil and dust, then this may affect the accuracy of the balancer it is recommended to clean these parts regularly.

2. Use the cone and flange carefully to avoid damage caused by accidental falling or knocking, which will affect the accuracy of positioning

Be careful not to  accidentally drop the cones or quick nut. Damage to these items will affect the balance accuracy.

If the damage is serious, it will affect the measurement results.

The cone and screw rod are often worn and knocked, which will cause damage  and accordingly affect the balance accuracy.

3. Keep the keypad and display panel clean

Wipe with a mild cleaner and moist cloth if necessary. Dirt and grease will cause the buttons and display panel to fail prematurely 

4. Regularly calibrate the balancer every three months or change of season. 

As the balancer is a precise measuring instrument, its accuracy is very important. The balancing machine is composed of circuit boards and mechanical components. Electrical parts are sensitive to temperature, humidity and other environmental factors. Mechanical parts have impact and  wear which  will happens when balancing. Recommend that you calibrate the machine on a seasonal basis. But the specific calibration cycle time should be adjusted according to the use of the machine, heavy use= more frequent calibration.

5. Keep the internal components clean.

The cable transmits the signal of the balancing machine. By keeping the internal components clean it will avoid- electric leakage, static whilst in use, prevent errors, other signal transmission problems

Circuit boards and wires that are dusty can also cause electrical fires

6. Check and lubricate the balance shaft regularly.

The balancing shaft is the main rotating component of the balancing machine. The motor drives the balance shaft to rotate, and then the balance shaft drives the tire to rotate.  Sensors give numerical feedback through the vibration of the balance shaft.

Dirty or dry bearings may cause damage. This leads to unstable readings.

Check and lubricate shaft regularly to ensure its stability. 

If there is a large friction in the rotation process, the rotation speed will not be fast enough to be measured, or errors will occur.

7. Check and tighten the belt every 6 months 

The belt is the link between the motor and the balance shaft. The balance shaft is driven by motor through the belt. Every 6 months the belt should be checked and tightened if required.  The belt is a consumable item so will require replacing every 2-3 years depending on use. 

8. Avoid impact between the rim and the shaft when balancing.

Avoid impact between the rim  and the shaft when balancing. So as to avoid damage of the  shaft or sensor caused by excessive force.

9. Don’t press the buttons with anything other than your fingers

The keypad is made of plastic and the backing is secured by M4 screws. Behind the back is the  circuit board. If you use an object like the weight hammer and press the keypad, the keypad will damage easily, causing the keypad to break and malfunction.

10. Don’t let the balancer get wet

It is prohibited to place any container with water or other liquids on the balancer and make sure that the equipment is free from water. The balancer doesn’t carry an IP rating.
