6.6 CORRECTION OF THE IMBALANCE
A. The wheel assembly automatically stops near the right weight correction plane.
NOTE: Automatic plane braking can be selected from the main function setup menu. Factory default is right
plane (2), select a value of “1” for braking on the left plane, “0” for none
.
B. Read the imbalance value of the right side. Values are displayed in ounces but can be displayed in grams if
required and are automatically rounded to the nearest commercial wheel weight.
C. Place the amount of weight called for. Use the foot operated shaft lock to stabilize the shaft during weight
placement if required.
D. Press “Start” with the hood up to rotate the assembly to the left or inner correction plane.
E. Place the amount of weight called for. Use the foot operated shaft lock to stabilize the shaft during weight
placement if required.
PROCEDURE WHEN SCANNER FAILS TO ACQUIRE A VALID PROFILE
If data for distance, diameter or width are missing it is not possible to balance a wheel since the balancer does
not have proper wheel data.
The unit will display the data (distance / diameter / width and weight placement mode) of the last wheel mea-
sured in RED color to indicate those data fields which might not be correct.
In the event of chasing weights, view the “Parameter” Screen and observe the values. If any parameter is
displayed in red, it has not been validated and the value must be manually entered to recalculate the proper
correction values. To change a value in the Parameter or Optima mode, the corresponding button must be
depressed twice. Modify the data by pushing and holding F3, F4 or F5 and turning the wheel until the desired
value is displayed.
After the wheel has been unclamped from the balancer, the balancer will switch back to the previous mode for
the next wheel assembly.
6.7 VERIFICATION OF THE RESULTS
Lower the wheel guard to spin the wheel again and check that the readout is “0.00” “0.00” If a residual imbalance
is displayed: Reference Graphic 1 next page for diagnostics explanation below.
A. Check the rim parameters, if entered value is incorrect, correct as needed. Imbalance values will be automati-
cally re-computed.
B. Check if the balancing mode selected is the most appropriate. If not, choose the right mode and re-spin.
C. The wheel weight could have been placed at a wrong position. To check this, position the wheel at the correction
position for the outer plane. If the wheel weight previously attached is in sector ‘ L ’ or ‘ R ’ ( Graphic 1, page 20), move
the wheel weight up about 1” (2.54cm).
If the wheel weight is in sector ‘ D ’ cut a piece of the wheel weight of an approximate value corresponding to the value
shown on the right display, or replace the wheel weight with a lighter one.
If the wheel weight is in sector ‘
U ’ add a weight of value indicated by the display or replace the wheel weight with a
heavier one. Repeat the same operation for the inner plane.
NOTE: If this situation is repeated, your machine may be out of calibration and a calibration operation might be
required, contact a service representative for re-calibration.
