10. OPTIMISATION
Optimisation means such positioning of wheel rim and tyre in relation to each other thet wheel
rim unbalance and tyre unbalance cancel themselves out which results in a smaller weight
needed for wheel balancing.
Unbalance of tyre and of wheel rim are measured in a twin measuring cycle and the
measurement result takes into account both balancing planes at the same time.
Optimisation should be performed as a preliminary operation before balancing the wheel by
means of weights . Before carrying out optimisation, enter wheel date in the machine memory
according to item . 8.3.1 - 8.3.4 .
OPTIMISATION
Mount wheel rim only in balancing machine chick so that valve holes are located precisely
opposite marks on spindle and chuck (see section.4).
Push - button
.MEASUREMENT OF WHEEL RIM ONLY image will appear on monitor.
Deprees START key again - balancing machine drive will start to be confirmed by [CAUTION
START] announcement. After the balancing machine has stopped WHEEL RIM ONLY
UNBALANCE message will appear on monitor screen stating unbalance point and value.
Remove wheel rim from chuck fit tyre and inflate to specified pressure. Mount complete wheel
in balancing machine chick in the same position as wheel rim alone was installed, i.e. valve
should face markers on chuck and spindle.Push - button
.Image TYRED WHEEL
MEASUREMENT will appear on monitor screen. Depress again START key - balncing machine
drive will start to be confirmed by announcement [ CAUTION START]
Upon completion of measurement cycle and machine stoppage image TYRED WHEEL
UNBALANCE will appear on monitor screen indicating wheel unbalance point and value
Push - button
.Image shown in Fig.28.will appear on the screeen.
After opening of wheel rim and tyre unbalance by rotating the wheel by hand and watching
indicators „1” and „2”. When indicator „1” will reach its top position and a sound signal will be
heard mark with chalk the top point on the wheel rim in vertical place through spindle centre
line. When indicator „2” will reach its top position ( sound signal will be heard ) mark with chalk
the topmost point of the tryre.
Remove wheel from balancing machine and shift tyre in relation to wheel rim in such a way that
chalk marks on rim and tyre are next to each other.
