The possible options are: OFF: disabled ON: enabled ALUS: enables wheel locking in position for the ALUS correction mode only. Laser Enable/disable laser for adhesive weight positioning. Note that offset arm locking will not be enabled when laser is activated. Select the most appropriate mounting method for the wheel you are balancing.
Standard Front Cone Mounting A wheel should be centered by the outer side of the hub only when the inner surface will not provide an accurate surface to center on. Shaft Shaft No-Mar Ring Cone Cone Hub Nut Face Plate Figure 9 - Alternate Mounting Face Plate Hub Nut Figure 8 - Front Cone Mounting 1. Select the cone that best fits the center hole in the wheel.
Setting Wheel Dimensions (DIM) Before a wheel can be balanced, wheel dimensions must be entered into the computer. Definition of Dimensions (DIM) Wheel Data Entry 1. To automatically enter A & D dimensions, pull the offset arm out and up against the wheel at the appropriate weight placement location; hold it still and wait for the deep or the display to change. W = Width The width of the wheel at the rim flanges, measured with the calipers or width sonar as shown in figure 17.
• For A1 data entry, move the arm from home position and place the offset arm up against the wheel flange in position A1, as shown in figure 15. • For A2 data entry, after taking the inboard measurement, move the offset arm to the inner area of the wheel; up against the rim at the outboard weight placement location, as shown in figure 15. Dimension screen buttons enabled: - automatic width measurement - automatic ALUS wheel measurement are: Static / Dynamic Toggle between Dynamic and Static balancing.
Balancing A Wheel Static Balancing A variety of wheel configurations can be balanced using this wheel balancer. Read through this section, it will help in determining which balancing options are best suited for certain wheel assemblies. Dynamic Balancing Choose a static balance to balance a wheel using one plane for correction. Place the single corrective weight at top-dead-center (12 o’clock) on either flange, at the center of the rim channel, placed inward either side, or split on either sides.
Attaching Corrective Weights Measurement Result After the wheel spins and out of balances are measured and displayed, the corrective weight amount appears on the video display for inboard and outboard weight locations. Arrows appear that are useful for positioning the corrective weight at the application point. If the out-of-balance is less than the chosen threshold value, - - - appears instead of the out-of-balance value to indicate, on that particular side, that the wheel is in tolerance.
Behind Spoke Runout “Splitting” weight is used to hide any adhesive weights behind the rim spokes. Runout result screen. Behind Spokes Enable split function of out of balance (see Behind Spokes). Indicate Exact Corrective Weight Position If laser disabled, indicates and locks arm when in correct horizontal plane (see Indicate Exact Corrective Weight Position). Special Functions Selection of special functions. Balancing Spin Lower hood, then spin wheel to check balance.
LASER ON: to split the out of balance measured in two different positions, proceed as follows: Position the static out of balance or outboard adhesive weight in the correction position and press button Indicate Exact Corrective Weight Position It is recommended that you always use this function to correct an out of balance using adhesive weights. Remember to thoroughly clean the application areas. : 1.
Match Balance (Optimization) Important: A high out of balance may indicate the improper mounting of the assembly on the balancer, or a rim that is out of round or misformed, or a tire with a bubble or other problem. If the out of balance is excessive, it may be prudent to replace the rim, the tire, or both. If either is replaced, do not continue with Match Balance. Balance the new tire and rim and evaluate the readings.

Match Balance To go into the Match Balance procedure. Result Screen To go to the result screen (the symbol above the button is displayed in yellow to indicate an excessive first harmonic eccentricity value).
Sonar LR Instruction 30 mm In order to obtain the correct lateral eccentricity values, the sonar cone must be positioned inside the tire shoulder. The function of the LED is to make it easier to position the sonar correctly, but always bear in mind that it does not indicate the focus of the pad as it is situated 30 mm further down. 4.
