The Hidden weight function can be disabled by
pressing the Hidden Weight.
Hidden Weight Programme is enabled even when
the operator inserts the wheel dimensions manu-
ally (possible anomaly of one or both lasers).
To start this programme, proceed as indicated be-
low:
- 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 or the
button on the monitor to confirm the operation;
- 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 or the
button on the monitor to confirm the operation;
- When the procedure is completed, the unbalance
image is displayed on the screen including two
position indicators for the outer side. The unbal-
ance 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
S78 Touch - Operator's manual
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):
A
- 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 removing 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.
NOTE: the eccentricity measuring programme cannot
be performed on motorcycle wheels.
- Select the MOTO environment using the
icon located in the secondary
control keypad
- select the dynamic balancing programme directly
from the touch screen monitor;
- set the wheel data manually as described in the
"MANUAL ENTRY OF WHEEL DIMENSIONS" section.
