7 ONLAND-USE (VARIOPAL OF)
7.1 General Instructions
The range 8 and 9 of the VariOpal are also
available as onland version. This version
can be used onland = O-operation or in the
furrow =F-operation.
O-operation = onland use behind a
crawler or a tractor
F-operation = use in the furrow behind a
tractor
Contrary to the VariOpal the VariOpal OF shows the adjustment centre Optiquick
with a long main link (1), a hydraulic ram (2) and a hydraulic ram (3) with lock
valve (4) for the frame swing-in procedure.
Attention: The lock valve (4) is used for switching on or off the frame swing-in
device during turning operation, only. In O-operation the lock valve
should be closed.
7.2 Conversion from F-Operation to O-Operation
For the conversion from working in the fur-
row (F-operation) to working onland (O-
operation) the inner hydraulic ram (2) must
be closed.
The outer hydraulic ram (3) must be ad-
justed so that the headstock is nearly in
right angle (90°) to the landslides of the
plough bodies.
The lock valve (4) must be closed after that
to switch off the frame swing-in assembly.
