1. Application
The SKF MultiPoint Automatic Lubricator LAGD 400 is an eight-point lubrication system.
The lubricator can be used with all standard SKF grease types and produces a maximum
pressure of 40 bar (600 psi). The maximum pressure is guaranteed when the total length
of the lubrication tubes does not exceed 5 metres (16 ft).

2.2 Method of operation
During each cycle, an electric motor in the lubricator pre-loads a piston. The piston draws
grease into a cylinder. The piston is released at the end of each cycle and pushes the
grease from the cylinder into the eight channels of the outlet block. The piston dispenses
the same quantity of grease through each channel.
The electric motor is controlled by a microprocessor. The microprocessor controls the
dispense modes and detects blocked lubrication tubes and empty grease cartridges.
2.3 Grease supply
A standard SKF grease cartridge supplies grease to the lubricator. An empty SKF grease
cartridge can be refilled through the grease filling nipple.
English

6SKF LAGD 400
2.4 Lubrication tubes
The lubrication tubes are made from black nylon that has a high bursting strength.
Genuine SKF tubes must be used. The grease can be pumped through the tubes a
minimum distance of 5 metres (16 ft). A maximum distance of 10 metres (32 ft) is
possible during favourable conditions. Favourable conditions include low viscosity grease,
high ambient temperature and low back-pressure at the application.
2.5 Contents
The lubricator is supplied with:
• 20 m (65 ft) of lubrication tube
• 8 lubricator tube nuts (complete with 16 compression fittings)
• 8 threaded connectors (G 1/4)
• 8 steel plugs for unused outlets
(Unused outlets must be plugged to ensure proper operation.)
• 2 Y-connectors
• 1 filling nipple
• 1 grease cartridge LGMT 2/0.4
Note Y-connectors:
One tube cannot feed two lubrication points through a Y-connector.
The grease always flows to the lubrication point with less resistance.
The other lubrication point will receive less than required.

4. Installation instructions
4.1 Mounting
Mount the lubricator to a firm surface. The vertical position is recommended. Attach the
bracket on the back of the lubricator to the firm surface with the four bolts. A template for
the mounting holes is included in this document.
The lubricator should not be mounted on vibrating machinery. Outside installation is
permitted if the lubricator is protected from rain and snow.
Note:
The lubricator should not be mounted on vibrating machinery.
4.2 Electrical connections
Connections to the electrical terminals must be made by a qualified electrician.
Do not switch the power on until the lubrication tubes are connected as described in
section 4.4.
Connect the AC power terminals to a 100 - 240 VAC, 50 - 60 Hz source or connect the
DC power terminals to a 24 VDC source.
The lubicator can be switched on and off by a remote machine through the steering
terminals. Connection to the steering terminals is optional. If the steering terminals are
used, the connection must be made through a voltage-free relay.
The lubricator is on when the relay opens the connection between the steering terminals.
The lubricator can activate a remote alarm through the alarm terminals.
The alarm terminals are connected to a voltage-free, normally-closed relay in the
lubricator. The relay opens the connection between the alarm terminals during an alarm
condition. The relay is rated for a maximum of 40 V and 30 mA.
The lubricator only operates when the power supply is properly connected, the circuit
between the steering terminals is open and the power switch is on.
Refer to the illustration and the table for more information.

4.3 Fitting the SKF grease cartridge
Remove the locking ring from the protection cover. Hold the protection cover tightly
to prevent the ejection of the spring. Remove the protection cover, the spring and the
follower plate. Remove the pull cap from the new grease cartridge. Put the new grease
cartridge into the lubricator. Remove the plastic ring from the piston cap of the new
cartridge, but keep the piston in position. The piston is necessary for the correct operation
of the lubricator. Install the spring, the follower plate and the protection cover. Tighten the
locking ring.
4.4 Connection of lubrication tubes to the lubricator
Carefully cut the lubrication tubes to the correct lengths for the application. Before
connecting the tubes to the application, the tubes must be filled with grease.
English

10 SKF LAGD 400
See section 4.5. Insert the tube through the lubricator tube nut and compression fitting
with the thick end of the compression fitting furthest away from the end of the tube.
Insert the tube into the required outlet of the lubricator until it will go no further. Then
tighten the lubricator tube nut. The compression fitting should grip the tube quite firmly.
Check that the lubrication tube is securely fitted.
In the event that the lubrication tube needs to be refitted, a new compression fitting must
be used.
In the event that a particular lubrication point requires more lubricant, simply connect two
outlets to each other by means of a Y-connector.
Unused outlets must be plugged. First unscrew the protruding grease outlet from the
lubricator. Then plug the threaded hole by means of one of the steel plugs provided.
Note:
Only use the supplied plugs to plug unused outlets on the lubricator.
4.5 Pre-filling of lubrication tubes
4.5.1 Manual pre-filling
You can use a grease gun to pre-fill the tubes. Put a length of lubrication tube into the
open end of the 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 tube with grease. If you
pump thick grease (NLGI class 2 or higher) into a long length of tube, the resistance will
be high. The high resistance causes the filling nipple to compress the lubrication tube. If
the end of the tube is damaged by the filling nipple, cut off the damaged end before you
connect the lubrication tube to the lubricator.
4.5.2 Automatic pre-filling
You can program the lubricator to fill a length of tube. Switch the lubricator off and push
the SET-button two times. A length is shown on the display. Push the +/- buttons to
adjust the length in steps of 50 cm (20 in). The maximum length is 500 cm (200 in).
Push the PUMP button to start the lubricator. The lubricator operates continuously at a
speed of approximately 19 cm/hour (7.5 in/hr) until the set length of tube fills with grease.
4.6 Connection of tubes to the application
Attach a G 1/4 connector to each lubrication point. If the G 1/4 connector does not fit,
make the connection with an SKF-type LAPN connection nipple (see 4.7).
Push the pre-filled tube into the connector approximately 10 - 15 mm (1/2 in).
Lightly pull on each lubrication tube to ensure that a firm connection made.
After steps 4.1 to 4.6 are complete, the lubricator can be used.

6. Grease refilling
We recommend that you use a standard SKF grease cartridge to make sure that only
clean, high-quality grease is used. However, you can fill an empty cartridge with other
grease if necessary.
6.1 Exchange of the grease cartridge
An empty cartridge causes an alarm. The alarm signal starts, and the ALARM and EMPTY
symbols flash on the display. Push any button to cancel the alarm. Push the ON/OFF
button. The OFF symbol appears on the display. Install a new grease cartridge as shown in
section 4.3.
Push the ON/OFF button to start the lubricator.
6.2 How to fill the lubricator with loose grease
Before you fill an empty grease cartridge with loose grease, make sure that the grease is
compatible with the grease in the tubes and the application. If you are uncertain whether
the grease types are compatible, contact SKF. Attach a grease gun or grease filler pump to
the grease filling nipple on the front of the lubricator for manual filling. A standard empty
grease cartridge with piston lid must be installed in the lubricator. Be careful not to overfill
the container.
7. Selection of SKF greases
SKF produces a range of high quality greases to suit a wide range of applications.
The greases listed in sections 7.1 and 7.2 are available in the standard SKF cartridge

8. Maintenance
The SKF MultiPoint Automatic Lubricator LAGD 400 has been designed for a long and
trouble free life and should last many years if used correctly. To maximise the operating
reliability of the unit, the following recommendations must be followed:
• Use only high quality, stable greases. The types of grease supplied by SKF are
suitable for most applications and are available worldwide.
• Use only new grease cartridges or fill used cartridges with clean grease through the
grease filling nipple.
• Do not expose the lubricants to contaminants since this can eliminate lubrication and
damage both bearings and lubricator.
In the event that the lubricator is damaged, switch off the power supply to the lubricator
immediately. There are no user serviceable parts inside the lubricator.
In the event of a malfunction, return the lubricator to your local authorised
SKF service centre.
