8 - Unbalance optimization
- This function serves to reduce the amount of weight to be added in order to balance the wheel.
- It is suitable for static unbalance exceeding 30 g.
- In many cases it is also possible to improve the residual eccentricity of the tyre.
- The operations described below should be carried out with great care in order to obtain the best results.
Press:
(Press if it is wished to cancel the
function).
- The display prompts the operator to rotate
the rim-tyre. Mark with chalk a reference sign on the
adapter and rim in order to refit the rim in the same posi-
tion of the machine.
(Use scale on the spindle).
- With the aid of a tyre remover, turn the tyre on the rim
by 180°.
- Refit the rim on the adapter in the previous position.
RH display: possible percentage reduction (symbol
) of the unbalance compared to the actual wheel
situation.
-
LH display: actual static unbalance which can be
reduced by wheel-rim rotation.
Turn the wheel under the outer LED’s light up:
mark the tyre in the 12 o’clock position.
In the same way, mark the rim corresponding to the
position indicated by the innermost LED’s.
- Make the two points to coincide.
- In this example, an 80% reduction of the static unbalance of 45 grams is achieved with a residual of approx. 9
grams.
8.1 - Visual wheel examination
In certain cases, it is considered appropriate to rotate the wheel with the guard open in order to check the
state of the tread.
- Press and with the other hand press .
- One complete measuring spin is performed. The function is disabled automatically at the end of the cycle.
WARNING! The use of this function is at the operator’s own risk and peril.
