Operation

1.To operate your Wheel Balancer, first ensure that it is properly assembled and level with your floor as discussed above.

2.Remove the Bubble Level (A) from the top of the Wheel Balancer to protect it from possible damage when placing the wheel on the balancer.

NOTE: Before balancing, remove all weights from the wheel rim, and assure that the wheel, tire and stem are in finished condition as they will be installed on the vehicle.

3. Place your wheel horizontally with the valve stem up on the balancer with the top of the Hub Support (C) protruding through the center of the wheel. Be sure that the wheel is level on the Hub Support

(C) by adjusting the alignment of the wheel

Bubble Level (A)to the concentric circles marked around the Hub Support (C).

4.Replace the Bubble Level (A) on top of the Hub Support (C).

5.The Bubble Level (A) will indicate an out-of-balance wheel by showing the bubble out of the center of the bullseye. The bubble will move toward the “light” side of the wheel.

6.Balance the wheel by placing wheel weights of various sizes (not included) on the rim side indicated as “light” by the Bubble Level (A). Careful placement of weights will result in the wheel being balanced. The bubble in the Bubble Level

(A) will be centered in the bullseye when the wheel is balanced.

WARNING: When balancing, only place the weights where they are needed. DO NOT hammer the weights in place while the wheel is on the Balancer. This will result in damage to the Balancer. Mark the position of the weights, and hammer them on to the rim after the wheel has been removed from the Balancer.

7.Recheck your work after you have installed the weights. Replace the wheel on the balancer with the valve stem up. Check to ensure that the bubble is centered in the bullseye. If it is not, remove the wheel from the balancer, remove the weights from the wheel, and start again from step 3 above. For best results it is inportant that your wheels are properly balanced before using them on your vehicle.
