2.5 Folding and Unfolding
2.5.1 Unfolding into the Work
Position
1. Open the machine if possible on level
ground, if this is not possible try and
orientate the machine so the drawbar
and tractor is pointing up any slope.
2. Fold down the light units and open the
inline hydraulic tap on the wing catcher
circuit (A).
3. Operate the wing circuit (yellow) spool.
This will then lower the catchers (B) then
open the wings out (C and D). Continue
to pressure the wings out keep pumping
until the wing cylinders have reached full
stroke.
When the wings are fully open they
will appear not to be parallel. This is
to enable the machine to ‘float’ over
uneven ground in work and is normal.
4. With the wings fully open (E) operate the
tilt (red) spool to lower the machine
rearwards (F). Continue to operate the
tilt spool once the working elements
have touched the ground to roll the
machine rearwards onto the DD roll (G).
NOTE: when tilting rearwards from
folded there will be a delay (5-15
seconds depending on flow) before the
machine begins to tilt. This is normal,
continue to pump oil as normal.
5. With the machine now tilted onto the
rear roll fully turn off the inline hydraulic
tap on the wing (yellow) circuit. This will
isolate the catcher arm circuit.
6. The machine is now ready to be set for
work.
