2. Installation
General
The SKF Multipoint automatic lubricators LAGD 1000 are designed to lubricate plant and
machines. They must not be used for vehicle lubrication. They are capable of delivering
greases up to NLGI grade 2. The pump units differ in the way they can be electrically
connected as well as in number of lubrication points they can supply.
2.1 Preparation of lubrication points
Initially, check all lubricating points for possible damage and test the permeability by
means of a grease gun or a different lubrication device.
When operating new machines, fill any existing cavities in bearing points with a respective
lubricant. Otherwise, bearing damage may occur as a result of insufficient lubrication.
Remove the grease nipples at the lubricating points.
Screw in the supplied connectors (G1/8) to the lubricating points.
Ensure cleanness. Even minor contamination may result in system errors
or bearing damage.
Fig 4 Check the permeability of the lubricating points and fill any cavities in the bearing points.

12 SKF LAGD 1000
Fig 5 Remove the grease nipples.
Fig 6 Screw in the connector fittings.
2.2 Pump unit preparation
Connection with uneven number of lubricating points If the number of lubricating points
to be supplied is uneven, two of the outputs located at the distributor of the pump unit
have to be connected by means of the enclosed connection bar (Fig 7). This is necessary
for a proper distributor operation. To be able to screw in the connection bar, you first have
to remove two adjacent fittings on the distributor.
Then, screw in the connection bar.
No distributor output must be closed, as this would block the distributor.
When two outlets are connected by means of the connection bar, the
output flow from the connection bar is twice the volume of a single outlet.
Ensure cleanness. Even minor contamination may result in system errors
or bearing damage.

13SKF LAGD 1000
Fig 7 Connection bar for progressive distributors
2.3 Pump unit installation
The pump unit should be installed in a way which ensures protection against dirt, splash
water and vibration but also provides for easy access to make sure that all further
installation works can be carried out without difficulty and the unit can be easily refilled
later. The liquid level of the reservoir should be clearly visible. The unit must be installed in
vertical position.
For installation, the unit is equipped with a connection flange with three fixing points.
Mount the SKF Multipoint automatic lubricators LAGD 1000 to the machine with the three
supplied M8 bolts, washers and self-locking nuts (Tightening torque: 16 Nm, 11.8 ft.lbs).
The unit should be mounted in a position that is protected to the greatest possible extent.
Where holes have to be drilled for installation, position these holes as shown below, using
the template in Appendix 1.
When drilling the mounting holes, be aware of possible sources of danger,
such as available supply pipes, other units, non-stationary parts and heat
sources. Ask the machine manufacturer to confirm the position of the
mounting holes
Fitting with less than three screws is not allowed and may result in
breakage of the assembly flange.
The installation surface must be even. Otherwise the assembly flange may
be overloaded when tightening the screws and break.
Mount the unit at a safe distance from other items and conform to local
installation and accident prevention regulations.

2.5 Lubricant filling
All LAGD 1000 units are supplied unfilled.
2.5.1 Suitability of greases
The grease reservoir can hold up to 1 litre (33.8 US fl. oz) of grease, and the lubricator is
supplied empty. SKF greases LGFP 2, LGGB 2, LGWA 2 and LGHB 2 are recommended to
be used in LAGD 1000 lubricators at temperatures down to -10 °C (14 °F).
For temperatures down to -25 °C (-13 °F), SKF greases LGWA 2 and LGGB 2 are suitable.
Greases with graphite such as LGEM 2 aren’t suitable for the LAGD 1000. For all other
SKF greases please contact SKF.
2.5.2 Compatibility of greases
Check for grease compatibility. If filling with a different grease to that already used in
application, it is always best to remove as much of the old grease from the units and pipes
as possible.
2.5.3 Initial filling of Lubricant
The lubricator reservoir is filled in via the conical head lubrication nipple shown as A in
Fig. 12. This can be done using a filler pump or a grease gun. However, an air driven,
battery driven or electrical driven filler pump or grease gun is recommended for ease of use.
Fig 12 Position of grease nipples for filling and purging.

17SKF LAGD 1000
When the unit is filled for the first time, the lubricant forces the follower (rubber ring plate)
upward until the overfill outlet hole is reached. As filling continues, the air escapes until
the entire reservoir is filled with lubricant. When excess lubricant starts to emerge from
the overfill outlet, stop filling completely. When topping up, take care not to let lubricant
emerge from the overfill outlet hole. The levels (minimum and maximum) of the grease in
the container are shown by the rubber ring below the metal plate. Figure 13 clearly shows
the minimum, maximum and overfill details.
Fig 13 Position of grease filling marks
2.5.4 Bleeding the system
Connect the grease gun to the nipple shown as B in figure 12, and pump until the
lubricant emerging from the distribution block is free of air. The pressure relief valve is
used to protect the entire lubrication system against excessive internal pressures. The
valve is set to open at a pressure of 150 bars. If the operating pressure increases beyond
150 bars due to a blocked progressive feeder or lubricating point, the valve opens, and
grease visibly emerges from the valve.
2.5.5 Installation of lubrication pipes
Carefully cut the lubrication pipe to the correct lengths for the application.

Fig 14 Shorten the plastic pipe
Use a grease gun to pre-fill the cut pipes. Firmly push the pipe into the open end of the
pipe filling nipple included with the lubricator. Connect the grease gun to the other end of
the filling nipple. Operate the grease gun to fill the pipe with grease. To remove the grease
filled pipe, push on the collar and at the same time pull out the pipe.
If the end of the pipe is damaged by the filling nipple, cut off the damaged end before you
connect the lubrication pipe to the divider block.
Push the pipes into the outlet of divider block. Lightly pull on each lubrication pipe to
ensure that a firm connection is made. The lubrication pipes can be routed.
Fix the lubrication pipes to suitable positions on the machine by means of the enclosed
cable ties. Cut the protruding ends of the cable tapes with scissors or a similar tool.
When routing the lubrication pipes, make sure that the pipes cannot be
bent, squeezed, sheared off nor rubbed through during operation.
Insert the pipes into the connectors fitted to the application. Lightly pull on each
lubrication pipe to ensure that a firm connection made.
Fig 15 Insert the plastic pipe into the fitting.
To detach the pipe, press the plastic pipe forcefully into the fitting and pull it out.

19SKF LAGD 1000
The lubrication pipes are made from black nylon that has a high bursting
strength. Genuine SKF pipes must be used. The grease can be pumped,
through the pipes, to a recommended distance of 6 meters depending on
environmental temperature (recommended ambient temperature
20 °C, 68°F)
2.6 Level monitoring
2.6.1 Visual monitoring of level
The transparent reservoir enables you to visually monitor the level. The level should be
checked at regular intervals for safety reasons. The current level can be precisely seen
from the position of the follower.
When the grease level in the reservoir drops below the “min” marking,
you must bleed the entire system. (see section 2.5.4)
TIP. If the grease level does not go below the “min” level, you do not need
to bleed the entire system.
2.6.2 Level switch
The SKF Multipoint automatic lubricators LAGD 1000 series are delivered with an
automatic level control function. When the level drops below the “min” marking, the
sequence of operations is stopped, and a fault message “FLL” appears in the display.
3. Selection of grease quantity for application
The SKF Dial Set CD ROM (MP3506) or LubeSelect for SKF greases
http://www.skf.com/portal/skf/home/aptitudexchange can be used to calculate the amount
of grease required over a given time period.
Example:
LubeSelect calculates the following grease requirement for a bearing over the relubrication
interval.
Grease L1 life (SKF re-lubrication interval), hrs 3800
Grease quantity replenish through lubrication holes, grams 155
Assuming that the grease has a specific density of around 0,9, the total amount of grease
required over the lubrication interval is 155/0,9 = 172 cm3
A complete internal cycle of the LAGD 1000 dispenses 0,2cm3 per outlet.
Therefore the number of cycles required is 172/0,2 =860 cycles
Over a period of 3800 hours, 860 cycles are required, that is: one cycle every 4,4 hours
(or two cycles every 8,8 hours and so on).
The LAGD 1000 can now be programmed accordingly, see section 4.3.2.
