To do this, turn the vent valve (1) by about one
1/2 turn. After the air has been released

the vent valve completely.
When disassembling hydraulic pipes and pumps,
fluid will flow from the hydraulic tank. In this case, a
vacuum pump can be supplied for the machine as
special equipment; when correctly installed, this
pump will prevent the hydraulic tank from draining
out.
For longer repair operations, a case with a complete
assortment of environmental protection plugs and
stoppers can be ordered. These can be used, for
example, to seal off disconnected pipes.
6.2 Package content
• Place the vacuum pump (3) on the hydraulic
tank. The vacuum pump must be at a higher
level than the fluid in the hydraulic tank.
• Press hose fitting (4) carefully into opening

• Run the cable (5) to the battery.
Connect the positive lead (6) to the positive
terminal first, then the negative lead (7) to the
negative terminal.
• Switch on vacuum pump (3) at switch (8).
The hydraulic system fluid is first pumped up
into the hydraulic tank. Air is then drawn
continuously into the hydraulic tank by the
