1.3 Qualied technical personnel
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 qualified 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 re-
sponsible for assigning tasks and areas of
responsibility and for the responsibility and
monitoring 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.

1.7 Assembly, maintenance, malfunctions, modication, shutdown, disposal 1.8 Intended use
Supply of lubricants within a dual-line sys-
tem following the specifications regarding
the pressure and flow range made in these
Instructions:
The limit values specified in the technical
data, particularly the maximum operat-
ing pressure of 350 bar, must never be
exceeded.
Any other or exceeding use is considered to
be improper use.
For ranges going beyond the specified ones,
