USE
Pump unit
1.
Connect the pump hose to the hydraulic
cylinder and check that the connections are
properly secured.
2.
Close the relief valve by turning it clockwise.
3.
Pump the handle up and down.
4.
Relieve the pressure by turning the valve
anticlockwise.
NOTE
The pump can be used in all positions between
horizontal and vertical. If the pump is tilted, the end
of the hose must be lowest.
MAINTENANCE
NOTE:
•
The bleed screw must be tightened to bleed before use. Close the bleed screw when in use.
•
When the tool is not being used, the pump unit’s relief valve must be left open.
•
The tool is filled with hydraulic oil at the factory. Only use approved oil.
•
Change the oil after extended use.
Checking the oil
To check the oil level, place the tool on a horizontal surface. Set the handle as high as possible; if the handle does
not reach the highest position there is not enough oil, and refilling is necessary.
Top up with oil
Put the tool in a vertical position. Unscrew the bleed screw and top up the oil.
Changing the oil
Drain the oil by removing the bleed screw and opening the relief valve. Make sure no contaminants enter the system.
Fill with oil of an approved grade as above.
