Operation
• Press the pedal of the main shaft lock to hold the
wheel in this position.
• Clean the fitting position before attaching the
adhesive weights.
• Fit the balancing weight and firmly press the
adhesive weight onto the rim.
• Fit the second adhesive weight in the same manner.
5.8.1.2 Weights application with feeler arm or
with laser pointer
The reading point on the rim is given by the upper right
end of the feeler (A and B, Fig.5-24a).
Based on the weights application system enabled (arm
or laser), the feeler must be positioned in different
positions (A for arm, B for laser) in order to achieve the
identical axial positioning of the adhesive weight on the
rim
5.4.2.1.
5.8.2
Check spin
It is good practice to perform a check spin after applying
the weights.
• Spin the wheel.
Having finished the Test Run, if the wheel is balanced
correctly, both the numerical indicators should indicate
0 and an OK should be displayed (Fig. 5-25).
Note
If there is no OK reading, dynamic unbalances below
the tolerance limit (suppression preset to 3.5 g) add to
a static unbalance above the tolerance limit.
To check how much imbalance is left:
• Select the FINE key, F3 (Fig. 5-25a).
Note:
The operator should decide if applying the
stated weight is necessary.
5.8.3
Results recalculation
After spinning a wheel it is possible to enter new rim
data or select another weight mode. The results are
recalculated automatically, if possible.
Selecting another weight mode
• Between NORMAL, ALU and STATIC: no additional
steps required.
To have a recalculation done:
• Select the required weight mode. Check and/or edit
rim or plane data when necessary.
• Rotate the wheel to the left plane WAP position and
apply the weight.
• Rotate the wheel to the right plane WAP position
and apply the weight.
• Perform a check spin.
