WARNING
Heavy equipment
May result in serious injury and/or property damage.
Secure the circuit breaker before charging it manually (e.g. during service on the work bench).
NOTE
To charge the spring mechanism, grip the handle firmly and carry out each stroke evenly, moving the lever down as far as it will go.
Despite a significant increase in the required actuating force, the lever must be moved as far in the ninth stroke as in the first eight.
When the closing spring is fully charged, the lever can be moved without resistance.
