Test run

After installation or inspection, carry out a test run:
1. Start up the machine without a load. To do this, close the circuit breaker and do not switch
2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue

Switching the machine off again while it is starting up and still running at slow speed should
be kept to a bare minimum, for example for checking the direction of rotation or for checking
in general.
Allow the machine to run down before switching it on again.
