3. Preventive maintenance

To get the best results and safest operation from
pumps, we recommend that you carry out the
following checks before connecting the pump to the
application:
• General state and cleanliness of the equipment
• Any excessive play in the movement of the
handle
• Oil leaks
• Operating efficiency of the oil release valve
• Damaged or badly fitted accessories
If any products are found to be damaged or
defective, mark them clearly and store them in a
specially designated area for unsuitable material.
Consider using the SKF repair service to get it back
in good working order.
4. Assembly and operating
instructions
The pump has a stop lever clip to lock the handle.
Do not transport the product without locking the
handle. In you see the lever clip in locked

position.

4.1 Positioning

Place the pump in a horizontal position where it is
stable and its feet are all in contact with the surface
it is standing on. Make sure there is enough space to
operate the handle over the complete handle stroke.

4.2 Oil

Remove the oil filler plug to check the oil level, it is
located at the back of the pump, see
sure there is sufficient oil to complete the operation.
Use the appropriate oil as described in chapter 2.6.
The oil filler plug also works as a safety valve. In
the event that too much oil is returned to the pump
reservoir, the plug will leak the superfluous oil to
ensure that the reservoir is not over-pressurised.

4.3 Prepare the application

Screw the appropriate THPN nipple, with G thread,
to the application. Screw on the loose quick
connection nipple (THPN 300-1) to the selected
THPN nipple: Maximum torque for the M16 thread
is 40 Nm / 29.5 ft-lb See
For dismounting of components make sure that
with the built up of oil pressure these are not
suddenly released and can't freely fly away from
the application. Position retaining or locknuts if
necessary.

4.4 Connecting and using the pump

1. Make sure the hose and pump are
depressurised.
2. Connect the quick connection coupling on the
hose to the quick connection nipple. Check the
locking of this connector.
3. Release the stop lever clip, see
4. Close the oil release valve clockwise, see
5. Operate the handle to pressurise the application
carefully, watch the pressure increase on the
gauge and the check the application. You can
now mount or dismount your application.
6. When finished the job at hand, open the oil
release valve to depressurise the application.
