Safety precautions
Read this instruction for use fully. Follow all safety precautions to avoid personal
injury or property damage during equipment operation. SKF cannot be responsible
for damage or injury resulting from unsafe product use, lack of maintenance or
incorrect equipment operation. In case of any uncertainties as regards the use of
the equipment contact SKF.
Failure to comply with the following could cause equipment damage and personal injury.
• Do ensure that the equipment is only operated by trained personnel.
• Do wear proper personal protective gear, such as eye protection and protective
gloves, when operating the equipment.
• Do inspect the equipment and all accessories carefully before use.
• Do not use damaged components or modify the equipment.
• Do use clean recommended hydraulic oils (SKF LHMF 300, LHDF 900 or similar).
• Do not use glycerin or water based fluids as a pressure medium.
Premature equipment wear or damage can result.
• Do not use the equipment above the stated maximum hydraulic pressure.
• Do not adjust safety valves to work at pressures above the maximum
working pressure.
• Do not extend the handle in order to reduce the required force to reach maximum
pressure. Use hand pressure only.
• Do not use the pumps with accessories, which are rated below the maximum
working pressure of the pump.
• Do use a pressure gauge to monitor the oil outlet pressure.
• Do ensure that all the air has been removed from the hydraulic system before
pressurising the hydraulic system.
• Do prevent the workpiece (e.g. bearing, gearwheel or similar item) from being
forcibly ejected upon sudden release of pressure (e.g. by use of retaining nut).
• Do not use damaged hoses. Avoid sharp bends and kinks when connecting hoses.
Sharp bends and kinks will internally damage the hose leading to premature failure.
Applying pressure to a damaged hose may cause it to rupture.
• Do not lift the equipment by the hoses or couplings.
• Do follow local safety regulations.
• Do service the equipment by a qualified hydraulic technician or SKF Repair Centre.
• Do replace worn or damaged parts with genuine SKF parts.

SKF 728619 E
1. Description
The 728619 E is a two stage pump. The pump supplies a high rate of flow
(20 cm³ per stroke) below the switching pressure. Above the switching pressure the flow
is automatically decreased to 1 cm³ per stroke.
A 3 metre long high-pressure hose is supplied to connect the pump to the workpiece.
One end of the hose has a quick-connection coupling for the connection to the pump.
The other end of the hose has a G 1/4” quickconnection nipple for the connection to the
workpiece.
The pump comes prefilled with SKF mounting fluid (LHMF 300).
A 1 litre can of mounting fluid is also included. These items are stored in a sturdy
metal box.
The pump has an oil outlet connection (P).
The pump also has a return connection (R), to return oil to the oil container.
The return connection can be connected to an external oil reservoir when the oil container
capacity is not sufficient.
The release valve is in the pump head. The pump includes a safety valve to prevent high
pressure that can cause damage to the pump. PR

3. Operating instructions
• Remove the container plug under the pump handle to check the oil level.
Make sure there is sufficient oil to complete the operation. Use oil with a viscosity
at operating temperature of 300 mm²/s (1 400 SUS) to mount bearings with the
SKF Oil Injection Method or a hydraulic nut. Use oil with a viscosity at operating
temperature of 900 mm²/s (4 100 SUS) for dismounting bearings.
• Hold the pump in a horizontal position and tilt forward as necessary to make sure
the oil supply is constant.
• Screw the quick connection nipple (G 1/4) tightly into the workpiece.
• Connect the hose to the quick connection nipple. To connect or disconnect the hose
you must retract the collar on the quick connector. Do not disconnect the hose while
the oil is pressurised.
• Move the release valve to the pump position. Do not tighten the valve too much.
The release valve is found on the side of the pump.
• Operate the pump until the pressure increases to the level necessary for your
application. When the pressure is more than 150 MPa (21 750 psi), the safety valve
will open.
• Last, open the release valve to let the oil flow back to the oil container.
