ROLLOMAXIMUM XL
Page 19
To prolong the ROLLOMAXIMUM's service life and the optimise the tilled
field finish, it is very important that the extend/retract outlet (marked:
Red) is set to the float position for field work.
If the outlet (marked: red) is not set to float position, this constitutes in-
correct use and in the worst case may cause the frame to break.
Adjustment of the hydraulic suspension on the middle cross-kill shaft
The hydraulic suspension on the front centre cross-kill shaft (A), transfers part of the
machine's total weight to the axle, but also has the task of helping the axle to vertically
avoid collisions with rocks or when driving on undulating terrain.
The pressure of this sus-
pension is set ex works
to 50 bar (B), which is
the optimum setting un-
der most conditions. The
manometer for this func-
tion is the first (C) of the
two
manometers
mounted on the ma-
chine. If it is wished to
change the pressure, the
stop cock (D) on the sin-
gle-acting
outlet
is
opened (marked: black),
the pressure adjusted
and the cock is closed
again.
If the pressure on the centre axle are not identical with that on the side arm
axles, the pressure in the hydraulic system may be dissipated and the sys-
tem should be refilled with oil. If, however, the earth piles up in front of the
centre axle or the it only clears rocks with difficulty, the pressure is too high
and should be lowered.
Never set the pressure higher than 70 bar, as this may damage the centre
axle and result in very uneven working of the field.
