3 Lift the pump above the cylinders
and keep it in the po-
sition where the plastic plug (2) is topmost. Remove the plug
and filling screw located inside the plug.
4 Press the spout of the filling bottle into the filling hole and
squeeze the bottle to make the oil enter. Let air flow into the
bottle, and fill the pump container completely with oil.
5 Replace the filling screw and plastic plug.
6 Vent the complete hydraulic set by closing the valve (3), open
the air vent screw (7) and pump until air void oil flows out. Close the
screw (7).
7 If a large oil amount escapes when venting, refill the
container.
The system is provided with bayonet couplings including non-
return valves which means that venting is necessary when filling
the container, only.
The non-return valves are opened by the pins located in the
centre of the male and female parts. If these pins get worn, replace
the couplings. Risk of blocking system.
If, exceptionally, it is necessary to operate the with couplings
not completely intact, it is advisable to open the air vent screw to
assure that the passage is open to all cylinders before tightening
the connection.
07.3.3 Dismantling hydraulically tightened screw
connections
1 Attach distance sleeves and hydraulic cylinders
according to Fig 07-12A. Screw on cylinders by hand.
2 Connect the hoses to the pump and cylinders according
to Fig 07-12B. Open the release valve (2) and screw cylinders
in clockwise direction to expel possible oil.
3 Screw the cylinders in counter-clockwise direction about
half a revolution (180
°
), otherwise the nut is locked by the
cylinder and impossible to loosen.
4 Close the release valve and pump pressure to the stated
value.
5 Screw the nut in counter-clockwise direction about half a
revolution with the pin.
6 Open the release valve and remove the hydraulic tool
set.
7 Screw of the nuts by hand.
