Only qualified technical personnel may in-
stall, operate, maintain, and repair the prod-
ucts described in this document.
Qualified technical personnel are persons
who have been trained, assigned, and in-
structed by the operator of the final product.
Such persons are familiar with the relevant
standards, rules, accident prevention regu-
lations, and assembly conditions as a result
of their training, experience, and instruction.
They are qualified to carry out the required
activities and in doing so recognize and avoid
any potential hazards. The definition of qual-
ified personnel and the prohibition against
employing non-qualified personnel are laid
down in DIN VDE 0105 and IEC 364.
Relevant country-specific definitions of
qualified technical personnel apply for coun-
tries outside the scope of DIN VDE 0105 or
IEC 364.
The core principles of these country-specific
qualification requirements for technical
personnel cannot be below those of the two
standards mentioned above.
The operator of the final product is responsi-
ble for assigning tasks and areas of respon-
sibility and for the responsibility and moni-
toring of the personnel. These areas must be
precisely specified by the operator.
The personnel must be trained and in-
structed if they do not possess the required
knowledge.
Product training can also be performed by
SKF in exchange for costs incurred.
