Note
When balancing wheels, please remember that cleanliness is ab‐
solutely essential, as indeed it is in the case of any other repair
work you carry out. Only then can you attain a flawless result!
Dirt and rust in the area of the contact surfaces and centre of the
wheel distort the result.
– Clean the contact surfaces, the centre of the wheel and the
recess on the inside of the wheel before mounting the wheel
on the wheel balancer.
– Mount the wheel with tyre on the wheel balancer.
