- Select one of the balancing programmes, ALU1
or ALU2;
- Perform a spin;
- At the end of the spin, if there is an unbalance
on the outer side (Pe), the machine will display
the Hidden Weight button on the main screen;
- Press this button;
- turn the wheel clockwise until you reach the
point where you want to apply the first outer
weight (P1) and align the centre of a spoke
with 6 o'clock;
- press the
button on the monitor to confirm the opera-
tion;
- turn the wheel anticlockwise until you reach
the point where you want to apply the second
outer weight (P2) and align the centre of the
second spoke with 6 o'clock;
- press the
button on the monitor to confirm the opera-
tion;
- When the procedure is completed, the unbal-
ance image is displayed on the screen includ-
ing two position indicators for the outer side.
The unbalance value displayed for this side
refers to the indicator in the centred position
condition.
Application of each of the two balancing weights
is at 12 o'clock.
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,
if necessary, into equal parts on the two sides;
procedure described in the STATIC BALANCING
section.

Programme
Proceed as follows to balance a motorcycle
wheel on two planes (dynamic balancing) using
clip weights:
- Fit the motorcycle wheel adapter on the wheel
balancer (A, fig. 19):
- Remove the hub;
- Insert the two screws provided into the holes
on the wheel contact flange.
- Tighten the screws on the adapter making sure
that it rests on the flange correctly.
- Mount the motor shaft on the adapter;
- Mount the wheel after selecting the centring
cones (one for each side of the wheel), tighten
with the appropriate ring nut using the spacers
necessary for coupling the securing cones to
the threaded part of the shaft.
IMPORTANT: the wheel must be fixed to the
flange so as to avoid any movement of the two
during the spin or braking phases.
NOTE: the eccentricity measuring programme
cannot be performed on motorcycle wheels.
- Select the MOTO environment using the
icon located in the CONFIGU-
RATION PROGRAMS
- select the dynamic balancing programme di-
rectly from the touch screen monitor;
- set the wheel data manually as described in the
"MANUAL ENTRY OF WHEEL DIMENSIONS"
section. To access the environment "manual
entry of wheel dimensions", press the FEED-
BACK WINDOW on the touch screen monitor in
