Operating Instructions
5. Servicing and Maintenance
Rear Roll to Mid Roll
1. Unfold the press unit (all other working
elements should remain in the transport
position).
2. Remove the depth control rod and the
shim storage tie rod (items 17&19 on
Page 128).
3. Put the wing circuit into float.
4. Remove the 6 nuts on the rampoint unit
and the 2 outer rampoint bolts (fold
cylinders).
5. Disconnect the hydraulic hoses on the
valve block (at ports F01 & FI1).
Pressure may be retained in the
circuit between the valve and the
cylinders. Although it shouldn’t be
necessary to remove the fittings
between the valve and the
cylinders, the de-pressurisation
procedure (page 35) should be
followed before doing so.
7. Remove the bolts from the lift (rotate)
cylinders on the carriage unit and lower
the upper roll carriageunit to the ground.
8. Remove the chassis support unit and
reattach the disc gang for safety.
9. Remove the remaining (rear) lower roll
carriage bolts and lower the roll to the
ground.
10. Remove wear pads for the roll carriage
from the rear position to the mid-mount
position (item 31 on Page 66).
11. Remove the bolts on the rear gang
mounting unit (as seen on Page 86).
12. Close the drawbar cylinder taps.
13. Carefully raise the machine until the
gang unit is clear of the mounting plate.
14. Drive forwards so the machine passes
through the rear gang hole and bolt into
position.
15. Raise the machine and place the rear
gangs into the transport angle setting.
16. Fully raise the machine and put the
maximum amount of shims into the lift
axle rams.
17. Open the drawbar taps and lower the
machine until the front gangs are just
clear of the ground so that the rear
gangs can clear the roll unit.
18. Reverse the machine until the back
gang is clear of the roll unit.
19. Raise the machine, take out the lift axle
shims before lowering the machine
again.
20. Raise the roll carriage unit to the
mounting plate at the mid-mount
position of the machine.
21. Re-insert the depth rod and the shim
storage bar.
22. Bolt on the top cylinder plate.
23. Lift the carriage unit and attach the rams
to the top.
24. Re-route hoses as per revised piping
for mid/rear roll configuration. Utilise the
the hoses from the toolbox (P13640 (3/
8" 1450mm long)) between the junction
and the valve to bridge the gap. Take
care whilst reconnecting the hoses to
the valve to put the
twin cable-tied
hose into port F01 (rod side) and the
single cable-tied hose into port FI1
(cylinder side).
25. Fit the rear drawbar (see page 70).
