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 mm
mount bearings with the SKF Oil Injection
Method or a hydraulic nut. Use oil with a
viscosity at operating temperature of 900 mm
(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
into the workpiece.

4. Maintenance

4.1 Filling the oil container

Set the pump on a flat, level surface to fill the oil
container. Remove the plug from the oil container.
Fill the oil container until the oil level is at the
bottom of the filling pipe. Do not fill the pump above
the bottom of the filling pipe. Too much oil in the oil
container can cause a malfunction.
Make sure that there is no air in the oil system.
Check for air in the oil system after the oil is
replaced and after maintenance to the pump is
complete. Operate the pump, and make sure that
only air-free oil is supplied from the hose.

• 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.
Use only clean hydraulic oils such as SKF LHMF 300
or LHDF 900.

4.2 Cleanliness

Do not let metal particles or other contamination
enter the pump or oil.
Contamination will decrease the service life of the
pump.
