7.2 Inspection

There are 2 opposing greasing channels in each of the end shields. These channels are
fitted with a grease nipple and a screw plug on the opposite side (see graphic entitled "Drive
end and non-drive end shields with grease nipples" in the "Lubrication" section).
Notice
You have to separate the active parts of the bearings to replace the grease that is in the
greasing channel.
Cleaning the cooling air passages
Regularly clean the cooling air passages through which the ambient air flows, e.g. using dry
compressed air.
Notice
The frequency of the cleaning intervals depends on the local degree of pollution.
Warning
Particularly when cleaning using compressed air, make sure you use suitable extraction
equipment and wear protective gear (safety goggles, respiratory filter, etc.).

Instructions relevant for safety
Notice
The required regreasing intervals for rolling-contact bearings are not the same as the
servicing intervals. It is essential to adhere to them.
Note
When servicing a three-phase motor, it is generally not necessary to dismantle it. The motor
only has to be dismantled if the bearings are to be replaced.
