7.8 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
off prematurely. Check whether it is running smoothly.
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.
2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue
to observe the machine for a while in no-load operation.
