the Hidden Weight button
the main screen.
- Press this button;
the internal laser pointer will automatically
move onto the outer plane (Pe).
- Turn the wheel clockwise until you reach the
point where you want to apply the first outer
weight (P1) and align the laser point with a
spoke.
- 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 laser point with
the second spoke.
- 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.
Each of the two balancing weights is applied as
described in the "Balancing weight application"
section.
The Hidden weight function is combined with the
Shift planes function to allow balancing weights
which are multiples of 5 grams to be used.
You can quit the Hidden weight procedure at
any time by simply pressing the Exit button
.
The Hidden weight function can be disabled by
pressing the Hidden Weight.
Motorcycle Wheel Balancing
Motorcycle wheels can be balanced in:
- Dynamic mode; when the wheel width is such
(over 3 inches) to generate significant unbalance
EM9980 - Operator's manual
on
button or the
button or the
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.
Motorcycle Dynamic
Programme
Proceed as follows to balance a motorcycle
wheel on two planes (dynamic balancing) using
clip weights:
- Fit the motorcycle wheel adapter AUMO on the
wheel balancer (A, fig. 19):

- 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.
- Fit the most suitable pin (depending on the
wheel's central hole) onto the shaft after remov-
ing the threaded hub.
- 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.
