2
Weight holder to locate the adhesive weight both
for identifi cation of subsequent fi tting position and
for actual fi tting of the balance weight
3
Adhesive weight held in weight holder
4
Gauge head to identify rim dimensions on a
variety of rim profi les
5

Ultrasonic detector
On the outer side of the rim the machine has an
ultrasound detector for the wheel width (outside of
rim) (Fig. 4-25).
The sonar has a tolerance of +/- 0.5''.
Such tolerance does not jeopardise the accuracy
of the balancing.

Laser (Pointer / Scanner)
Figura 4-25
The machine has a laser scanner to automatically ac-
quire the wheel distance and diameter (inside of rim).
The machine uses the Laser Pointer to indicate the
precise point for fi tting the adhesive weights on the
rim (
5.8).

Note:
If the machine is set in Gauge arm mode as default, the
Laser Pointer mode can be activated by calling service.
Prolonged exposure to laser beams may damage
the eyes.
CAUTION:
AVOID DIRECT OR REFLECTED
EYE CONTACT WITH THE LASER
· Laser beams used in Snap-on products are rated
as Class II.
