Machine description
2.1 PURPOSE
The C71/2 EVO, C71/2SE 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 tem-
perature range of 0° to + 45°C.
The machine can operate only on flat non resilient floor.
To lift the machine, lever only on the base where the 3
support points are located. never, under any circustance,
apply force to other points such as the spindle, head, or
accessory shelf. It functions properly without having to
fasten it to the floor with wheels weighing up to 35 kg; for
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)
▪ laser for weight application at 5 o’clock (only SE)
▪ automatic width (option)
