check, while the <strong>motor</strong> is at standstill, that:<br />
•= the <strong>motor</strong> foundation has no indentations or cracks.<br />
•= the carbon brushes and the commutator are in perfect condition and the<br />
commutator contact surfaces have a uniform skin.<br />
•= the brush holders are correctly aligned and secured.<br />
•= the carbon brushes in the brush boxes and the brush pressure fingers in the<br />
links move easily and the spring action of all carbon brushes is even.<br />
•= the remaining brush height is still sufficient to ensure uninterrupted operation up<br />
until the next inspection. Make sure the height does not drop below the<br />
minimum brush height.<br />
Any defects detected in the course of the inspection must be corrected<br />
immediately.<br />

Danger<br />
If no inspection windows are fitted and therefore the respective covers need to be<br />
removed in order to observe the commutation behavior, this must always be done<br />
by specially qualified expert personnel in order to reliably ensure that no live or<br />
moving parts are touched.<br />
Protective goggles must be worn.<br />
With the <strong>motor</strong> running, check that:<br />
•= the specified technical data is complied with (such as power consumption,<br />
temperature of the windings, bearings, coolant, etc.).<br />
