11.0 AIR CONNECTION
On models with pneumatic chuck
EACH PNEUMATIC INTERVENTION
MUST BE CARRIED OUT BY PRO-
FESSIONALLY QUALIFIED STAFF.
IN CASE OF A CHANCE SUP-
PLY FAILURE, AND/OR BEFORE
ANY PNEUMATIC CONNECTIONS,
MOVE THE CONTROLS TO THE
NEUTRAL POSITION.
Connect the wheel balancer to the centralised com-
pressed-air system by means of the connection on the
back of the machine (see
Fig. 28
).
The air system supplying the machine must be able
to supply filtered and de-humidified air at a pressure
between 8 and 10 bar. It must feature an on-off valve
upstream of the machine.

12.0 FITTING THE WHEEL ON THE
CHUCK
To achieve perfect balancing, the wheel must be care-
fully and properly fitted on the chuck. Imperfect cen-
tring will inevitably cause unbalances.
WHAT IS MOST IMPORTANT IS
THAT ORIGINAL CONES AND
ACCESSORIES, SPECIALLY DE-
SIGNED TO BE EMPLOYED WITH
THE WHEEL BALANCERS, ARE
USED.
Wheel fitting using the cones provided is illustrated be-
low. For alternative fittings, using optional accessories,
refer to the special instructions provided separately.
12.1 Wheel assembly
For models with threaded chuck
1. Remove any type of foreign body from the wheel
(
Fig. 29 ref. 3
): pre-existing weights, stones and
mud, and make sure the chuck (
Fig. 29 ref. 1
)
and the rim centring area are clean before fitting
the wheel on the chuck.
2. Carefully choose the cone (
Fig. 29 ref. 2
) most suit-
able for the wheel to be balanced. These accessories
must be selected according to the shape of the rim.
Position the wheel (
Fig. 29 ref. 3
), fitting the cone
(
Fig. 29 ref. 2
) on the chuck (
Fig. 29 ref. 1
): be
careful (otherwise this could seize) until this rests
against the support flange (
Fig. 29 ref. 4
).
3. Fit the wheel with the inner side of the rim towards
the wheel balancer and against the cone.
