measures and work instructions.
○Carry out transport using suitable trans-
port and hoisting equipment on suitable
ways only.
○Maintenance and repair work can be
subject to restrictions in low or high tem-
peratures (e.g. changed flow properties
of the lubricant).Therefore, where pos-
sible, try to carry out maintenance and
repair work at room temperature.
○Prior to performing work, the product
and the machine, into which the product
will be integrated, must be depressur-
ized and secured against unauthorized
activation.
○Ensure through suitable measures that
movable or detached parts are immobi-
lized during the work and that no limbs
can be caught in between by inadvertent

cording to the information in the valid
wiring diagram and taking the relevant
regulations and the local connection con-
ditions into account.
○Do not touch cables or electrical compo-
nents with wet or damp hands.
○Fuses must not be bypassed. Replace

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

load-bearing capacities only. If no tightening torques are stated, apply tightening tor-
ques 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.

○Corrosion protection
○noise minimisation
○protection against contamination or
penetration of foreign objects
○cooling (primarily with oils)

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 lu-
brication 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 viscosi-
ties, see chapter Technical data.

2.Lubricants
Only lubricants specified for the
product 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 lubri-
cation 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 manually.
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 cen-
tralized lubrication systems (e.g.
incompatibility between synthetic
lubricants and materials). In
order to avoid this, always use
lubricants tested by SKF.

1 Housing
Includes the motor, the control pcb and the
electrical connections of the EDL1.
2 Cover plate (pcb access)
The transparent cover plate allows to imme-
diately detect operating and fault status mes-
sages by the LED on the control pcb.
The cover plate must be disassembled by re-
moving the 4 screws in order to:
○change the position of the DIP switches
○install the power and control lines to the
respective connecting terminals
○carry out an additional lubrication cycle or
a reset of the EDL1
3 Cable gland
Serves to duct and fix the connection and
control lines The EDL1 has 3 cable ducts. Two
of them are closed by blind plugs (3.1. If these
cable glands are required, corresponding cable
fittings (3) can be ordered as accessories.
