5. Checking machine oscillation
Access to the wheel balancer oscillation test function:
▪ From the main panel, press the [MENU] button
▪ Press the button [7] Special functions
▪ Press the button [3] Machine self-test
▪ Simultaneously press the buttons [5] + [6] to enable the wheel balancer test functions (for specialised personnel
only).
▪ Press the button [5] Auto
▪ Set the number of test spins (recommended value = 20)
▪ Set the time between one spin and the next (recommended value = 5 sec.)
▪ Press the [START] button.
The wheel balancer runs the number of spins set in automatic cycle and provides the maximum oscillation value.
6. Checking machine calibration
With the wheel perfectly balanced, apply 100 g first on the outside and then on the inside.
The wheel balancer must measure:
FI=0
FE=100
Weight F.E. = position = 6 o’clock
FI=100
FE=0
Weight F.I. = position = 6 o’clock
Max. permitted tolerance 100 g = 5%.
7. Checking the adapter
Turn a fine balanced wheel upside down (180°) and detect unbalance rates
ERR.MAX =
This check-out in particular must be made with a sample wheel whose max unbalance errors due to centering are
well known (generally lower than 10 gr. for iron wheels).
