Replacing the DOSING ROLLER
Perform this operation while the dosing chamber is empty:
A) Empty hopper;
B) Hopper with product: use the movable panel (P, Fig. 303)
to exclude feeding from the hopper to the doser. Then empty
the dosing chamber.
1) Remove the belt from the agitator and fully disconnect the
metering roller transmission (Fig. 304).
2) Take out the bearing support of the metering roller (G, Fig.
306);
3) Take the metering roller out sideways (H, Fig. 306) ...
To re-assemble, follow the steps in reverse order.
IMPORTANT: before starting seeding, open the panel (P, Fig.
303) to feed the doser.
FEELER PIN
The feeler unit may also be easily disassembled in a single block in a matter of minutes for cleaning purposes. It consists of 5 single
hatches that are spring-loaded to ensure tight closing. The hatches do not touch the seeding wheel while it is in operation! Thanks to
the separators xed between one hatch and the next, it is possible to activate each element independently of the others. Moreover, the
separators are shaped in such as way as to act as a shield against foreign bodies that could damage the dosing roller. The hatches are
adjustable, and their shape has been speci cally designed to adapt to the seeds.
Always use gloves. The new parts especially might have sharp edges that could injure the operator!
1) In order to disassemble the feeler unit, loosen the four nuts of the axles (front and back) (Fig. 307), using a 13 mm spanner ...
2) until it is becomes possible to push out the discs tted inside, remove them from their seats (Fig. 308) and move the axles.
3) Remove the back part (Fig. 309) of the feeler pin unit, rst, followed by the front part.
When the hatch is disassembled, it is also possible to remove the emptying hatch, by
sliding it out from below.
On completion of cleaning, re-assemble the unit by following the above mentioned steps
in reverse order, taking care to position the at parts of the axles correctly! Put the feeler
pin unit in place. Then slide the washers back in their housing and nally tighten the nuts
by hand.
Once the hatch has been mounted, the elements must be mobile. To check that they
are, simply push them with your ngers (Fig. 310). If they do not move, it is advisable to
disassemble them and clean them.
During re-assembly, before tightening the various parts, ensure that the rear part
of the hatch (on the spring side) is not too high. Install the dosing roller in order to
ensure that the height is correct.
