Eagle’s Wheel Balancer Calibration Procedure

Our service department has gotten a few calls lately asking how to calibrate their Eagle wheel balancer. It is important to read the operation manual before you start using any of Eagle Equipment’s service equipment. Eagle’s wheel balancers do not to be calibrated when you receive them. To allow our customers the ability to begin using their machine right away, our balancers are calibrated before they are shipped.

The main reason a balancer needs to be re-calibrated is because it begins to “chase weight”. “Chasing weight” means the balancer continues to ask for more weight once the first weight is applied. At this point, the machine needs to be calibrated.

Below is the Wheel Balancer Calibration instructions for models: EB-1040, EB-1070 and EB-1090. Follow these steps in order to properly calibrate your Eagle Wheel Balancer. Please call 1-800-336-2776 for any assistance.

EB-1040/ EB-1070
Only calibrate the balancer if there are problems balancing tires (such as chasing weight, etc.) Be careful to follow each step precisely, correctly and accurately. A balanced tire is preferable, but not necessary; so long as there is no physical damage to the rim.

Do not use a tire with a bent or damaged rim.

Do not attempt to calibrate the balancer with a rim only. You must use a complete tire and rim assembly.

1- Turn the unit on. Mount a medium size (14″ – 15″) tire on the shaft, and enter the three (3) parameters (Distance, Width and Diameter), as described above.

2- Press D+C button. Display will show [CAL][CAL]. Hold the D and C buttons until the indicators stop blinking, then release the buttons.

3- Lower the hood, and press the START button. The tire will spin. After it stops, the display will read: [Add][100].  Attach a 3.5oz. (100g) weight on the outside of the wheel rim.

4- Lower the hood, and Press the START button, again. The tire will spin a final time.  After it stops, the display will read: [End][Cal].

5- The self-calibration is complete. Turn the machine off, then on again to ensure the data is stored properly. This the most important step.

(Self-Calibration values are stored in memory and maintained when the machine is turned off, with storage lasting about 10 years. However Self-Cal may be performed whenever values are in doubt.)
