ALU 3 balancing programme:
Calculates statistically the balancing weights to be
applied on the inner part (inner and outer side)
of the rim, as illustrated by the icon.
ALU 4 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner side and the inner part,
outer side of the rim, as illustrated by the icon.
ALU 5 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner part and the outer side
of the rim, as illustrated by the icon.
- Correctly set the wheel data as described for
the Dynamic balancing program.
- Perform a spin.
- at the end of the spin, select the balancing
programme icon
knob or the ENTER button until the required
programme is selected.
- When the position is centred, the screen will
show where to place the balancing weights for
the selected programme: always at 12 o'clock
if the weight is of the traditional spring type
(or adhesive, but outside the rim); to apply the
adhesive weight inside the rim, use the 6 o'clock
point as your reference if "LASER" configuration
is active, or 12 o'clock if the configuration is
"H12" or CLIP.
- The video displays instructions for where to
position the balancing weights relating to the
selected programme: always to 12 o'clock if the
weight is a conventional spring type, whereas
for the application of the adhesive weight, use
6 o'clock if the "LASER" configuration is active
or 12 o'clock if the "H12" or CLIP configuration
EM 9580 Plus - EM 9580 C Plus - Operator's manual
and press the Kis
is active.
- Set the wheel's rated geometric data by follow-
ing the steps described in the WHEEL DATA
ENTRY chapter. If the values of the diameter and
of the distance between the balancing planes,
recalculated on a statistical basis starting from
the rated geometric data of the wheel, exceed
the normally accepted interval stated in the
TECHNICAL DATA section, the A 5 message is
displayed.
IMPORTANT: in ALU1 and ALU2 programmes
the unbalance displayed by the machine on the
outer side refers to the adhesive weight centre
of gravity at the shaft assembly bearing flange,
see figure 25a.
- Some slight residual unbalances may remain at
the end of the test spin due to the considerable
difference in shape that may be found on rims
having the same rated dimensions. Therefore
change the value and position of the previously
applied weights based on the configuration
performed in the programme "SELECTION OF
ADHESIVE WEIGHTS APPLICATION POSITION"
until an accurate balance is obtained.
Motorcycle Wheel Balancing
Motorcycle wheels can be balanced in:
- Dynamic mode; when the wheel width is such
(over 3 inches) to generate significant unbalance
components which cannot be eliminated with
static balancing (the recommended procedure).
- Dynamic mode for alloy rims; a programme
similar to the ALU programmes for on-vehicle
wheels, featuring the possibility of dividing
the weight of one side into two parts in case
of particularly large spokes.
- Static mode; just one balancing weight, divided,
