Attaching balance weights

i
After the balance weights have been attached, the im-
balance must be measured again to check the balance.
8.3.1 Standard procedures for clip-on weights and
adhesive weights
Attach balance weights to inside of rim, facing the ma-
chine.
1. Turn tire by hand.
 The relevant indicator lights up and the warning
tone sounds once the balancing position has been
reached.
2. If a clip-on balance weight is selected, a balance
weight is fitted in the 12 o"clock position (see left-
hand display panel A for value). For adhesive balance
weights, use the automatic rim-distance gage.
Fit balance weights to outside of rim.
1. Turn tire by hand.
 The relevant indicator lights up and the warning
tone sounds once the balancing position has been
reached.
2. Attach clip-on weight or adhesive balance weight in
the 12 o"clock position (see right-hand display panel D
for value).

ALUS balancing mode

i
The position of the adhesive balance weights is de-
termined by the automatic rim distance gage.
i
The left-hand display panel A shows the 1st bal-
ancing plane, while display panel D shows the 2nd
balancing plane.
1. Turn tire by hand.
 The relevant indicator lights up and the warning
tone sounds once the imbalance point is reached.
2. Actuate pedal to hold the flange shaft.
3. Fit the required adhesive balance weights to the
head of the rim-distance gage.
4. Pull out the rim-distance gage.
5. If the left-hand window displays "――口" and if the
warning tone sounds, the point directly on the head
of the rim-distance gage is the balancing position.
i
In this way, attach weights to both balancing planes
of the wheel. The pedal light lights up while the ped-
al is being depressed to hold the flange shaft firmly.
8.3.3

Splitting the balance weights (HID program)

i
For ALUS, the balance weights can be split to con-
ceal them behind the spokes.
i
After measurement, to split the balance weights,
please press "T+OPT". If Hide lights up, this means
that the HID function can be used.
1. Press the "T+OPT" key.
 Indicator panel B displays 12 o"clock.
2. Rotate tire until corresponding position on outer
side lights up. Press "ALU" key for confirmation
purposes.
3. Indicator panel B displays "-1-". Rotate tire, move
left-hand spoke with imbalance point to 12 o"clokc
position on the flange shaft. To confirm, press "ALU"
key.
4. Indicator panel B displays "-2-". Rotate tire, move
left-hand spoke with imbalance point to 12 o"clokc
position on the flange shaft. To confirm, press "ALU"
key.
5. Indicator panel B displays "SPD". On the outside of
the tire are two split balancing points. Correspond-
ing position on the outer side lights up, actuate
pedal to hold flange shaft in place.
6. Fit the required adhesive balance weights to the
head of the rim-distance gage.
