properly maintain the equipment can result in death, serious injury, or product

maintenance steps necessary to ensure safe operation of the equipment.
Particular applications may require further procedures. Should further
information be desired or should particular problems arise which are not
covered sufficiently for the purchaser's purposes, the matter should be referred
to the local Siemens sales office.
