8.2.2 Pressure vessel
Never open or adjust (welding, drilling etc.) the pressure vessel (pressure accumulator). The
pressure vessel is still under gas pressure even after it has been emptied.
Empty the pressure vessel in case of any work on the hydraulics of the machine. The manometer
must not show any pressure, or the pressure on the manometer must decrease to 0 bars. Only
then it is permitted to work on the hydraulic circuit.

8.3 Folding and unfolding of the machine
•
The hydraulics for the folding and unfolding must be connected to the double-action control
unit.
•
The operator must ensure that during folding and unfolding of the side frames, no person or
animal is within their reach (i.e. at the place of their impact) or vicinity.
•
Perform folding and unfolding on flat and solid
surfaces or laterally to the slope with the fully
open control unit.
•
Execute the folding or unfolding only with a
machine that is raised on the axle with the side
rollers in the recessed position, i. e. their piston-
rods should be drawn in.
•
Remove stuck soil from folding points, soil may impair function and cause damage to the
mechanics.
•
During folding or unfolding, check the side frames and have them continuously fold into the
end position to the stoppers.
CAUTION!!! The machine must be lifted on the axle, when the machine is folded and unfolded.
Otherwise, the rollers may get damaged.
