- Preliminary operations
Before starting planting, position the machine on flat
ground and carry out the following operations.
1) Check that the plant spacing is correct (see "Adjust-
ing the plant spacing" - page 22).
2) Check that the row spacing is correct (see "Adjusting
the row spacing" - page 20).
3) Assess the soil consistency in order to adjust the dis-
tance between the packing wheels and the plough-
share using the knob (B) (see "Adjusting the spacing
between the packing wheels and the ploughshare"
- page 17).
4) Decide whether the gap between the packing wheels
is large enough to ensure the correct pressure is ap-
plied to the root ball (see "Adjusting the packing ef-
ficiency" - page 18).
5) Turn the levers (E) by the same amount to set (de-
pending on the model) the dispensing unit(s) paral-
lel to the ground.
6) Use the knob (A) to adjust the furrow depth (see
"Planting depth adjustment" - page 19).
7) Use, alternatively, the handwheel (C) and the nut (D)
to adjust the load of the packing wheels (see "Adjust-
ing the planting unit load" - page 23).
8) Use the nut (D) to apply the load of the driving wheel
to the ground (see "Adjusting the driving wheel load"
- page 19).
9) Position the trays (F) safely in the tray holder.

- Planting operations
1) To prevent overloads on the ploughshare, the tractor
driver must lower the work vehicle with the tractor
moving forwards at low speed. Do not reverse the
tractor with the work vehicle on the ground as this
could damage the ploughshare.
2) Stop the tractor and let the operators get on the work
vehicle.
In the planting stage, the operators on the work vehi-
cle must adopt a correct posture with their feet rest-
ing on the footboard (G) and must agree - together
with the tractor driver - on the most effective speed
of travel.
3) Load the seedlings into the dispenser and keep it
loaded during the planting stage.
Do not load the seedlings into the front cups as they
are continually opening and closing.
4) The operators on the work vehicle must decide on
the tractor's speed of travel together with the tractor
driver so that a least 60 seedlings can be placed in
the dispenser per minute and correct ejector/seed-
ling timing is obtained.
5) Move forwards with the tractor before starting the
planting.
6) The operators on the work vehicle must check the
planting quality constantly. In the event of anoma-
lies, stop the tractor moving forwards and adopt cor-
rective measures (see "Information on adjustments"
and "Troubleshooting"- pages 17 and 32).
