Any usage differing from the one stated in
these Instructions is strictly prohibited. It is
expressly forbidden to be used:
○outside the indicated operating tempera-
ture range
○with non-specified means of operation.
○without adequate pressure control valve
○in continuous operation
○in areas with aggressive or corrosive ma-
terials (e.g. high ozone pollution). These

○All parts are correctly installed
○All warning labels on the product are
present completely, highly visible and
undamaged
○Illegible or missing warning labels are to
be replaced without delay
○All components used must be designed
according to the maximum operating
pressure and the maximum respectively
minimum operating temperature.
○No parts of the centralized lubrication
system may be subjected to torsion,
shear, or bending.
○Check all parts prior to their usage for
contamination and clean, if necessary.
○Lubricant lines should be primed with
lubricant prior to installation. This makes
the subsequent ventilation of the system
easier.
○Observe the specified tightening torques.
When tightening, use a calibrated torque
wrench.
○When working with heavy parts use suit-
able lifting tools.
○Avoid mixing up or wrong assembly
of dismantled parts. Mark these parts
accordingly.
1.20 Cleaning
○Risk of fire and explosion when using
inflammable cleaning agents Only use
non-flammable cleaning agents suitable
for the purpose.
○Do not use aggressive cleaning agents.
○Thoroughly remove residues of cleaning
agents from the product.
○Do not use steam jet and high pressure
cleaners. Electrical components may be
damaged. Observe the IP type of protec-
tion of the pump.
○Cleaning work may not be carried out on
energized components.
○Mark damp areas accordingly.

Personal injury/ material damage due to
falling of raised parts A B C G H K Keep unauthorized persons away. No people may remain under suspended loads. Lift parts with adequate lifting devices.
Personal injury/ material damage due to
tilting or falling of the product because of
non-observance of the stated tightening
torques
B C G
Observe the specified tightening torques. Fix the product only to components with
sufficient load capacity. If no tightening torques are stated, apply tightening torques
according to the screw size characteristics for 8.8 screws.
Personal injury/ material damage due to
electric shock in case of damage to the
connection cable
B C D E F G H
Check the connection cable with regard to damages before the first usage and then
at regular intervals. Do not mount cable to moving parts or friction points. If this
cannot be avoided, use spring coils respectively protective conduits.
Personal injury/ damage to material due
to spilled or leaked lubricant B C D F G H K
Be careful when filling the reservoir and when connecting or disconnecting lubricant
feed lines. Always use suitable hydraulic screw connections and lubrication lines
for the stated pressures. Do not mount lubrication lines to moving parts or friction
points. If this cannot be avoided, use spring coils respectively protective conduits.

2. Lubricants
2.1 General information
Lubricants are used specifically for cer-
tain application purposes. In order to fulfil
their tasks, lubricants must fulfil various
requirements.
The most important requirements for lubri-
cants are:
○Reduction of abrasion and wear
○Corrosion protection
○Noise minimisation
○protection against contamination or
penetration of foreign objects
○Cooling (primarily with oils)
○longevity (physical/ chemical stability)
○economic and ecological aspects
2.2 Selection of lubricants
SKF considers lubricants to be an element
of system design. A suitable lubricant is se-
lected already when designing the machine
and forms the basis for the planning of a
centralized lubrication system.
The selection is made by the manufacturer
or operator of the machine, preferably to-
gether with the lubricant supplier based on
the requirement profile defined.
Should you have little or no experience with
the selection of lubricants for centralized
lubrication systems, please contact SKF.
If required we will be glad to support cus-
tomers to select suitable components for
feeding the selected lubricant and to plan
and design their centralized lubrication
system.
You will avoid possible downtimes through
damage to your machine or system or
damage to the centralized lubrication
system.
2.3 Material compatibility
Lubricants must generally be compatible
with the following materials:
○steel, grey iron, brass, copper, aluminium
○NBR, FPM, ABS, PA, PU
2.4 Temperature characteristics
The lubricant used must be suitable for
the specific operating temperature of the
product.The viscosity required for proper
operation of the product must be adhered
to and must not be exceeded in case of low
temperatures nor fall below specification in
case of high temperatures. Specified vis-
cosities, see chapter Technical data.

Version 02
EN 2. Lubricants
Only lubricants specified for the
product (see chapterTechnical
data) may be used. Unsuitable
lubricants may lead to a failure
of the product.
Do not mix lubricants. This may
have unforeseeable effects on
the usability and therefore on
the function of the centralized
lubrication system.
When handling lubricants the
relevant safety data sheets and
hazard designations, if any,
on the packaging have to be
observed.
2.5 Ageing of lubricants
After a prolonged downtime of the machine,
the lubricant must be inspected prior to
re-commissioning as to whether it is still
suitable for use due to chemical or physical
ageing. We recommend that you undertake
this inspection already after a machine
downtime of 1 week.
If doubts arise as to a further suitability of
the lubricant, please replace it prior to re-
commissioning and, if necessary, undertake
initial lubrication by hand.
It is possible for lubricants to be tested in
the company's laboratory for their suitability
for being pumped in centralized lubrication
systems (e.g. "bleeding").
Please contact SKF. if you have further
questions regarding lubricants.
You may request an overview of the lubri-
cants tested by SKF.
Due to the multitude of possible
additives, individual lubricants,
which according to the manu-
facturer's data sheets fulfil the
necessary specification, may
not, in fact, be suitable for use in
centralized lubrication systems
(e. g. incompatibility between
synthetic lubricants and materi-
als). In order to avoid this, always
use lubricants tested by SKF.
