6.9 Optimisation

ATTENTION: Optimization is to be performed as a preliminary operation to
wheel balancing using correction weights.

Optimization  is  a  control  test  of  a  wheel  providing  rim  and  tyre  alignment  checking  to
ensure  that  imbalances  coming  from  both  cancel  each  other  out.  It  helps  diminishing  the
imbalance  of  the  wheel  and  using  smaller  weights.  Imbalances  of  both  rim  and  tyre  are
performed  in  two  measurement  cycles  and  the  result  takes  both  correction  planes  into
account.

Realisation of the procedure:
After mounting a bare rim in the holder in a specific way - easy to remember (e.g. valve
matching the position of the marker on the spindle fig. 5.2) input the following parameters:
Width, Diameter and Distance.
Pressing results in entering the optimization program and appearance of the following
on the display:

Initiating optimization is done the same way as with a regular imbalance measurement
(chapter 6.7). After completing the first part of the measurement and the spindle stops
rotating the following will appear on the displ^RTH

The operator should dismount the bare rim from the holder, put a tyre on the rim, inflate to
a  specified  pressure  value  and  mount  it  on  the  holder  the  same  way  as  the  bare  rim  was
mounted  before  (e.g.  valve  and  marker  way).  Starting  another  cycle  results  in  calculation
of the values and positions of rim and tyre imbalances as well as the new positioning of the
tyre  relative  to  the  rim.  Additionally  a  profit  will  be  evaluated  (thrift  of  weight  amount).
Locating  the  positions  indicated  by  the  machine  on  the  tyre  and  the  rim  is  analogous  to
finding  the  external  (right)  hammered  weight  in  regular  imbalance  calculation.  Both
positions should be marked (e.g. using chalk).
Lastly the operator should dismount the wheel from the handle, position the tyre on the rim
so  that  both  marked  places  are  as  close  to  each  other  as  possible.  Inflate  the  wheel  to  the

specified pressure value and mount it on the machine’s spindle in order to balance it. In
order to leave the OPTIMISATION program press the key at any time.
If the tyre's position relative to the rim is optimal, there is no profit and hence the displayed
value is zero.

Mark this position on the rim.

Mark this position on the tyre.
