CAUTION
Risk of injury!
Open the screw cap only when
the lubricant reservoir is emptied
(MINimum level).
Filling the reservoir above the Min
mark (MINimum level) places the
spring of the grease follower plate
under tension. Opening the screw
cap can cause abrupt release of the
spring’s tension.
○All relevant persons must be informed of
the activity prior to the start of the work.
Precautionary operational measures and
work instructions must be observed.

○Transport only with suitable transport
and lifting gear on marked paths.
○Maintenance and repair work can be
subject to restrictions at low or high tem-
peratures (e.g., change in lubricant flow
properties). Maintenance and repair work
should therefore preferably be performed
at room temperature.
○Prior to performing work, the product
and the machine in which the product will
be integrated must be depressurized and
secured against unauthorized activation.
○
Take appropriate measures to ensure that
moving, detached parts are immobilized
during the work and that no limbs can be
pinched by unintended movements.
○Assemble the product only outside the
operating range of moving parts, at an
adequate distance from sources of heat
or cold. Other units of the machine or the
vehicle must not be damaged or their
function impaired by the installation.
○Dry any wet, slippery surfaces or cover
appropriately.
○Cover hot or cold surfaces appropriately.
○Work on any additional electrical compo-
nents may be performed only by quali-
fied electricians. Note possible waiting
times for discharge. Work on electrical
components may be performed only with
voltage-insulated tools.
○Drill required holes only on non-critical,
non-load-bearing parts. Use existing
boreholes. Do not damage lines or cables
when drilling.
○Observe any possible wearing spots. Pro-
tect components appropriately.
○All components used must be designed
for:
- The maximum operating pressure
- The maximum/minimum ambient tem-
perature
- The lubricant to be delivered
- The operating and ambient conditions
at the place of use.
○No parts may be subjected to torsion,
shear, or bending.
○Check parts for contamination before use
and clean if necessary.
○Lubrication piping should be filled with
lubricant prior to assembly. This simplifies
subsequent bleeding of the system.
○Adhere to the specified torques. Use
a calibrated torque wrench when
tightening.

2. Lubricants
2. Lubricants
2.1 General information
Lubricants are used specially for specific
applications. To fulfill the task, lubricants
must meet various requirements to varying
degrees. The most important requirements
for lubricants are:
○Reduction in friction and wear
○Corrosion protection
○Noise reduction
○Protection against contamination/
ingress of foreign matter
○Cooling (primarily for oils)
○Durability (physical/chemical stability)
○Compatible with as many materials as
possible
○Economic and environmental aspects
2.2 Selection of lubricants
SKF Lubrication Systems considers lubri-
cants to be an element of system design.
The selection of a suitable lubricant should
reasonably be made during the design of the
machine and forms the basis for planning
the centralized lubrication system.
The manufacturer/operator of the machine
should preferably make the selection with
the supplier of the lubricant on the basis of
the requirements profile of the specific task.
If you have no or little experience selecting
lubricants for centralized lubrication sys-
tems, please contact SKF.
We gladly assist our customers in the selec-
tion of suitable components for feeding the
selected lubricant and in the planning and
design of a centralized lubrication system.
This will spare you potentially costly down-
time due to damage to the machine/system
and/or damage to the centralized lubrication
system.
Only lubricants specified for the
product may be used (see “Tech-
nical data” chapter). Unsuitable
lubricants may lead to failure of
the product.
Do not mix lubricants. This can
have unpredictable effects on the
usability and this function of the
centralized lubrication system.
NOTE
Large air bubbles can cause failure of
lubricant supply. SKF therefore recom-
mends electrical monitoring for the
system. Ensure filling without introducing
air! In case of error, bleed the HTL201.

- 18 -
951-171-044-EN
Version 01
EN 2. Lubricants
Due to the large number of
possible additives, individual
lubricants that meet the required
specifications according to the
manufacturer’s data sheet are
under some circumstances not
suitable for use in centralized
lubrication systems (e.g., incom-
patibility between synthetic lu-
bricants and materials). To avoid
this, always use lubricants that
have been tested by SKF.
2.3 Material compatibility
The lubricants must generally be compatible
with the following materials:
○Steel, gray cast iron, brass, copper,
aluminum
○NBR, FKM (FPM), ABS, PA, PU
2.4 Aging of lubricants
In case of extended machine downtime,
check before putting back into operation that
the lubricant is still suitable for use in terms
of chemical and physical signs of aging. We
recommend performing this inspection after
one week of machine downtime.
In case of doubt regarding the suitability of
the lubricant, replace it before putting back
into operation and, if necessary, perform an
initial lubrication manually.
It is possible for lubricants to be tested in the
company's laboratory for their suitability for
pumping in centralized lubrication systems
(e.g., "bleeding").
Please contact SKF if you have further ques-
tions regarding lubricants.
An overview of the lubricants we have tested
is available on request.
