!All SKF products must only be used for their intended pur-
pose and in accordance with the specifications of the in-
stallation instructions for the product in question.
!You must observe the machinery manufacturer's infor-
mation on the lubricants to be used in the machinery.
DANGER!
The manufacturer of the bearing or machinery to be lubri-
cated will specify the lubricant requirements for each point to be
lubricated. You must make sure that the required quantity of lu-
bricant is provided to the relevant lubricating point. If a lubricat-
ing point is insufficiently lubricated, the bearing may become
damaged or jammed.
!If required, SKF can help customers to select suitable
components for the conveyance of the selected lubricant
and to plan and design their centralized lubrication system.
2. Lubricants
2.1 General
The intended use of this product is for the centralized lubrication/lu-
brication of bearings and wear points with lubricants. All physical
limitations of use stipulated in the documentation of the product
such as the owner’s manual, technical drawings and catalogs must
be observed.
More specifically, we call your attention to the fact that substances
and mixtures classified as hazardous by the Annex I part 2-5 of the
CLP regulation (EC 1272/2008), and identified with hazard picto-
grams GHS01-GHS06 and GHS08, can only be used to feed the SKF
centralized lubrication systems, transported or distributed by these
systems after consultation with SKF and obtaining written
permission.
All products manufactured by SKF are not approved for use in
conjunction with gases, liquefied gases, pressurized gases in solution
and fluids with a vapor pressure exceeding normal atmospheric
pressure (1013 mbar) by more than 0,5 bar at their maximum per-
missible temperature.
Should there be a need to use the product to convey media other
than lubricants or hazardous substances, this must be discussed
with SKF first and the company must give express written
permission.
In the opinion of SKF, lubricants constitute a design element that
must be considered when selecting components and designing cen-
tralized lubrication systems. The lubrication properties of the lubri-
cants in question must be considered.
2.2 Selection of lubricants
While the machinery/bearing manufacturer usually specifies lubri-
cants, it is the owner/operator (or maintenance person) who must fi-
nally select the appropriate lubricant, with the help of the lubricant
supplier. When selecting a lubricant, the type of bearing/wear point,
the stresses and strains to be expected during operation, and antici-
pated ambient conditions must be taken into account. All financial/
economic aspects must also be considered.
If you have further questions, you can contact SKF.
We can test lubricants in our own laboratory to establish their
suitability for conveyance (e.g. 'oil separation' behavior) in centralized
lubrication systems.
You can request an overview of lubricant tests offered by SKF from
our Service Center.
1.5 Warranty
The instructions do not contain any information on the warranty.
This can be found in the General Conditions of Sales, which are avail-
able at: www.skf.com/lubrication.

DANGER!
Only lubricants that have been approved by SKF for use
with the product may be used. Unsuitable lubricants can cause
product malfunctions and damage to property.
DANGER!
Different lubricants must not be mixed together. Doing so
can cause damage and require extensive cleaning of the prod-
ucts/centralized lubrication system.To prevent confusion, we
recommend that you attach information indicating the lubricant
to be used on the lubricant reservoir.
The described product can be operated with lubricants that comply
with the specifications in the technical data.
Note that some lubricants may have properties that lie within the
permitted limit values and yet not be suitable for use in centralized
lubrication systems for other reasons. For example, some synthetic
lubricants are not compatible with elastomers.
DANGER!
Lubricants can contaminate the ground and watercourses.
Lubricants must be used and disposed of in compliance with the
rules. Instructions and local regulations must be observed when
handling lubricants.
DANGER!
Centralized lubrication systems must be absolutely leak-
free. Leaking centralized lubrication systems can cause a slip
hazard. When performing installation, maintenance, and repairs
test the centralized lubrication system for leaks. Leaky parts of
the centralized lubrication system or components of the lubrica-
tion equipment have to be sealed immediately.
Leaking centralized lubrication systems or components of the lu-
brication equipment are a source of danger in relation to slip hazard
and the risk of injury. These dangers can cause physical injury to per-
sons or damage to other material assets.
Refer to safety precautions in the lubricant manufacturer's mate-
rial safety data sheet.
Lubricants are hazardous substance. It is essential to respect any
safety instructions given in the lubricant safety data sheet. You can
ask the manufacturer of the lubricant for the material safety data
sheet.
2.4 Lubricants and the environment
Note that lubricants are harmful to the environment and flammable;
their transportation, storage, and processing are subject to special
precautionary measures. For specifications on transportation, stor-
age, processing, and dangers to the use and the environment for the
lubricant, refer to the material safety data sheet provided by or avail-
able from the lubricant manufacturer. You can ask the manufacturer
of the lubricant for the material safety data sheet.
