C71/2 EVO, C71/2 EVO SONAR, C71SE/2 EVO is used
to balance the wheels of cars, vans, 4-WD, motorcycles
and scooters weighing less than 75 Kg. It can be operated
in the temperature range of 0° to + 45°C.
The machine can oper ate only on fl at non resilient fl oor.
To lift the machine, lever only on the base where the 3
support points are located. never, under any circustance,

heavier wheels, fasten it at the points indicated. Do not
mount anything other than motorbike, car or truck tyres
on the wheel balancer.
Thanks to the new and exclusive VDD (Virtual Direct Drive)
system, reliable unbalance measurements can be made
in a short time, almost half the time of the cycle used with
respect to other balancers in this range.
The main features include:
machine settings menu. ▪
optimisation of tyre and rim unbalance. ▪
static programme, ▪ ALUS; SPLIT ; Unbalance optimiza-
tion; indication of exact correction weight position; Self
diagnostics; Self calibration.
automatic minimisation of static unbalance
▪
wheel locking (only SE) ▪
automatic width (option) ▪
