general statutory regulations and other
binding regulations for accident preven-
tion and environmental protection
(recycling/disposal) must be observed
and applied.
Authorized personnel
Only qualified personnel may install, operate,
maintain and repair the components described
in these instructions. Qualified personnel are
persons who have been trained, assigned and
instructed by the system operator. Such per-
sons are familiar with the relevant standards,
rules, accident prevention regulations and op-
erating conditions as a result of their training,
experience and instruction. They are autho-
rized to identify and perform necessary actions
while avoiding potential risks. The definition of
qualified personnel and the prohibition against
employing non-qualified personnel are laid
down in DIN VDE 0105 and IEC 364.
Electric shock hazard
Only appropriately trained qualified personnel
may establish electrical connections for the de-
vices in observance of the local conditions for
connections and local regulations (e.g., DIN,

2. Lubricants
2.1 General information
All products from SKF Lubrication
Systems Germany GmbH may be used
only for their intended purpose and in
accordance with the information in the
product's assembly instructions.
Intended use is the use of the products for the
purpose of providing centralized lubrication/
lubrication of bearings and friction points using
lubricants within the physical usage limits
which can be found in the documentation for
the devices, e.g. assembly instructions/operat-
ing instructions and the product descriptions,
e.g. technical drawings and catalogs.
Hazardous materials of any kind, especially the
materials classified as hazardous by CLP
Regulation EC 1272/2008 may only be used to
fill SKF centralized lubrication systems and
components and deliv-ered and/or distributed
with the same after consulting with and re-
ceiving written approval from SKF.
No products manufactured by
SKF Lubrication Systems Germany GmbH are
approved for use in conjunction with gases, liq-
uefied gases, pressurized gases in solution, va-
pors or such fluids whose vapor pressure ex-
ceeds normal atmospheric pressure (1013
mbar) by more than 0.5 bar at their maximum
permissible temperature. Other media which
are neither lubricant nor hazardous substance
may only be fed after consultation and written
approval from SKF Lubrication Systems
Germany GmbH. SKF Lubrication Systems
Germany GmbH considers lubricants to be a
component of the system design which must
be factored into the selection of components
and the design of centralized lubrication sys-
tems. The lubricating properties of the lubri-
cants are critically important in these
considerations.
2.2 Selection of lubricants
Observe the instructions from the
machine manufacturer regarding the
lubricants that are to be used.
The amount of lubricant required at
a lubrication point is specied by the
bearing or machine manufacturer. It
must be ensured that the required
quantity of lubricant is provided to the
lubrication point. The lubrication point
may otherwise not receive adequate
lubrication, which can lead to damage
and failure of the bearing.
Selection of a lubricant suitable for the lubrica-
tion task is made by the machine/system man-
ufacturer and/or the operator of the machine/
system in cooperation with the lubricant sup-
plier. The bearings/friction points that require
lubrication, their expected load during opera-
tion and the expected ambient conditions are
taken into account during selection in consid-
eration of economic and environmental as-
pects.

Page 11 EN
Assembly instructions
Where necessary, SKF Lubrication Systems
Germany GmbH supports customers in the se-
lection of suitable components for feeding the
selected lubricant and in the planning of the
SKF lubrication system.
SKF Lubrication Systems Germany
GmbH supports customers in the
selection of suitable components for
feeding the selected lubricant and in
the planning and design of a lubrication
system. Please contact SKF Lubrication
Systems Germany GmbH if you have
further questions regarding lubricants.
Lubricants can be laboratory tested for
feedability (e.g., "bleeding") in central-
ized lubrication system applications.
An overview of the lubricant tests
offered by SKF Lubrication Systems
Germany GmbH can be requested from
the Service Center of SKF Lubrication
Systems Germany GmbH.
2.3 Approved lubricants
Only lubricants approved for the prod-
uct may be used. Unsuitable lubricants
can lead to failure of the product and to
property damage.
Different lubricants cannot be mixed, as
mixing may result in damage and ne-
cessitate costly and complicated clean-
ing of the product/lubrication system.
It is recommended that an indication of
the lubricant in use be attached to the
lubricant reservoir in order to prevent
accidental mixing of lubricants.
The product described here can be operated
using lubricants that meet the specifications in
the technical data. Depending on the product
design, these lubricants may be oils, fluid
greases or greases. Oils and base oils may be
mineral, synthetic and/or rapidly biodegrad-
able. Consistency agents and additives may be
added depending on the operating conditions.
Note that in rare cases, there may be lubri-
cants whose properties are within permissible
limit values but whose other characteristics
render them unsuitable for use in lubrication
systems. For example, synthetic lubricants may
be incompatible with elastomers.
2.4 Lubricants and the environment
Lubricants can contaminate soil and
bodies of water. Lubricants must be
properly used and disposed of. Observe
the local regulations and laws regarding
the disposal of lubricants.
It is important to note that lubricants are envi-
ronmentally hazardous, flammable materials
which require special precautionary measures
during transport, storage and processing.
Consult the Safety Data Sheet from the lubri-
cant manufacturer for information regarding
transport, storage, processing and environ-
mental hazards of the lubricant that will be
used.

4.2 General information
4.2.1 Hydraulic line connection (General)
The hydraulic line must be connected to the
lubrication unit in such a way that no forces can
be transferred to the assembled lubrication unit
(stress-free connection).
Warning
Before connecting the lubrication unit
to the hydraulic supply, it must be
ensured that the hydraulic supply is
depressurized.
Warning
The maximum hydraulic oil pressure
indicated for operating the hydraulically
actuated lubrication unit may not be
exceeded.
4.3 Lubrication line arrangement
Observe the following instructions when ar-
ranging the main lubricant lines and lubrica-
tion point lines in order to ensure that the
entire lubrication system functions smoothly.
The main lubricant line must be dimensioned
in accordance with the maximum pressure that
occurs during operation and the delivery vol-
ume of the lubrication unit used. If possible,
the main lubricant line should rise upward
from the lubrication unit and be ventable at
the highest point on the lubrication line sys-
tem. Lubricant distributors at the end of the
main lubricant line must be installed such that
the lubrication point lines point upwards. If the
system configuration requires that the lubri-
cant distributors be arranged below the main
lubricant line, they should not be placed at the
end of the main lubricant line.
The pipes, tubes, shutoff valves and directional
control valves, fittings, etc. that will be used
must be designed for the maximum operating
pressure of the lubrication unit, the permis-
sible temperatures and the lubricants that will
be delivered. All components of the lubrication
line system such as pipes, tubes, shutoff valves
and directional control valves, fittings, etc.
must be carefully cleaned before assembly. No
seals should point inward in the lubrication line
system, as this could hinder lubricant flow and
introduce contaminants into the lubrication
line system.

Page 15 EN
Assembly instructions
The FK grease lubrication pump unit must be
