NOTICE
Danger caused by loosening of the balancing weights as result of ineffective screw
securing
If you loosen the balancing weights already screwed in place by the manufacturer (e.g.
for the prebalanced rotor) you destroy the lock against inadvertent loosening.
Retightening is not permitted because of the ineffective screw lock.
• Replace the loosened balancing weights with new balancing weights.
• If required, newly placed balancing weights can be loosened, moved and retightened
within two hours. The screw lock becomes effective after 2 hours. If loosened after
two hours, the balancing weights must be replaced with new balancing weights.
