Maintenance

Through careful and regular maintenance, inspections, and overhauls you can detect faults at

an early stage and resolve them. This means that you can avoid consequential damage.
Operating conditions and characteristics can vary widely. For this reason, only general

maintenance intervals can be specified here. Maintenance intervals should therefore be

scheduled to suit the local conditions (dirt, starting frequency, load, etc.).
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions (Page 13)
● Comply with the applicable national and sector-specific regulations.
● When using the machine within the European Union, comply with the specifications laid

down in EN 50110‑1 regarding safe operation of electrical equipment.

Note
Please contact the service center (Page 121), if you require support with service, maintenance

or repair.

9.1

Inspection and maintenance

9.1.1

Safety instructions for inspection and maintenance

WARNING

Rotating and live parts
Electric machines contain live and rotating parts. Fatal or serious injuries and substantial

material damage can occur if maintenance work is performed on the machine when it is not

stopped or not de-energized.
● Perform maintenance work on the machine only when it is stopped. The only operation

permissible while the machine is rotating is regreasing the roller bearings.

● When performing maintenance work, comply with the five safety rules (Page 13).
