The machine described in this “Use and Maintenance" booklet is a pump designed to
handle non-homogeneous animal waste or industrial plant processing residue that is diffi-
cult to pump. The solid residue contained in the sewage is broken down by the double
chopper with which the AFI pumps are equipped (blade / counter-blades and rotor /
counter-rotor), making it easier to transfer.
Thanks to the AFI pumps, the sewage may be:
- collected and input into the collection tanks;
- conveyed to the fertigation system pipes;
- loaded onto tankers for transportation.
AFI pumps feature carbide mechanical seals.
Manufactured in various models with variable performance and power absorption. The
following operation options are available: cardan joint, electrical or hydraulic drive mo-
tors.
Technologically, this machine was also built in accordance with the concept applied to all
DODA products:
"Highest quality to obtain the maximum reliability and durability."
Fig. 1 shows a pump with cardan transmission. The
gear ratio is specified on the plate located on the
PTO box. Various models of the pump are avail-
able, with or without a cart or support frame.
Fig. 2 shows the same model
with an electric motor. The
plate on this pump specifies the
connection type and voltage.
Various models of this pump
are also available, with or with-
out a truck or frame.

3. GENERAL WARNINGS
1) Check that no component has been damaged during transportation. If damage has
occurred, contact your dealer immediately.
2) The power connection must be carried out in accordance with the DODA instructions,
by qualified personnel (by connecting the cables of the electric motor to the power or
the pump to the tractor by Cardan shaft). DODA is in no way responsible for the
electrical connections (please follow the instructions on the motor plate and the
sticker which indicates the direction of rotation).
3) Before starting the machine, check that the rotating parts of the transmission are
adequately protected as required by their manufacturer.
4) The protection of the rotating parts not supplied with the machine must be performed
by the operator based upon existing provisions of law.
5) DODA accepts no responsibility for changes that alter the characteristics of the
purchased machine.
6) DODA machines may not be installed on structures that do not comply with EC
safety requirements.
7) Before operating the machine, it is essential to read the instructions contained in the
Use and Maintenance Booklet.In particular, ensure that you have fully understood
how the machine operates.
8) The machine was designed and constructed to treat water and sewage, but not
chemical products. Treating the latter substances may cause permanent damage.
9) Check that the length of the machine is appropriate to the depth of the tank.
10) With regard to machines with oil bath transmission, the transmission pipe and the
gear units, if present, should be filled with oil.
11) During assembly, ensure that the rubber parts of the machine do not come into
contact with oil, grease or oil derivatives.
12) The pump must never be run under no-load operating conditions (see
"OPERATION").
page 4

4. PRELIMINARY CHECKS page 5
The machines are supplied without lubricating oil both in the transmission pipes and
the gear units. Before starting the machine, ensured they are filled correctly:
- unscrew the caps: fill and breather;
- very slowly add SAE90 oil (ISO VG150 for HD and IV) (see oil quantity tables);
- wait at least 3 hours (ONLY FOR TRANSMISSION PIPES) before checking the oil
level from the relevant cap;
- close the caps.
- check the level cap periodically: the oil must never fall below the level.
If the machine is equipped with a vacuum pump (11 fig. 2), the relevant tank (12 fig. 2)
must be filled with fluid oil (hydraulic) to lubricate the vanes.
FOR PUMPS WITH HD AND IV UNITS:
These pumps are equipped with a special double chamber suction cone, which circu-
lates and cools the lubrication oil for the step-up gearbox. In this case, proceed as fol-
lows:
- fill the step-up gearbox,
- fill the double chamber of the suction cone,
- start the hydraulic pump of the step-up gearbox moving, so that the oil that has al-
ready been introduced circulates throughout the hydraulic circuit. Check the level in the
cone and in the step-up gearbox, and top up as necessary.

5. POSITIONING AND TRANSPORTATION page 6
N.B.: for machines equipped with a cardan
joint, connect the cardan shaft between the
tractor's power take off and the machine
unit. For proper functioning, the cardan
shaft must be parallel to the ground when
operating.
Also check that the chain, supplied to protect the cardan transmission, is connected to the
dedicated ring, and that the protective devices are intact.
N.B.: for all machines with electric motor, DODA is not responsible for any electrical
connections (follow the instructions on the motor plate and the sticker which indicates the
direction of rotation).
N.B.: for transporting the machine over long distances, load it onto an appropriate vehi-
cle, following the instructions in the paragraph “MACHINE LOADING AND
UNLOADING”. Never use the tractor for road transportation.
AFI pumps must be placed in the immediate vicinity of the place
where suction is to be applied. Connect the suction pipe and the delivery pipe as required.
Thanks to the pressure supplied by these pumps, the suctioned material can be transferred
long distances or used to feed pressure-based spreaders.

6. OPERATION
WARNING: prior to starting the machine, read the “GENERAL WARNINGS” chapter.
After establishing and ensuring the stability of the machine, it may be used.
Steps for start-up:
- start the tractor;
- fill the suction cone with water or sewage using the dedicated inlet (2 fig. 3). Use the
vacuum pump for quicker priming. See the "OPTIONAL EQUIPMENT" chapter.
- activate the tractor power take off;
- increase the tractor revolutions until the pump starts (the priming time varies based on
the depth of the tank and the density of the suctioned material);
- bring the tractor back to the required number of revolutions.
Steps to stop:
- deactivate the tractor power take off by progressively decreasing the speed of the PTO;
- stop the tractor motor;
- disconnect the cardan shaft from both the tractor and the pump;
- remove the suction pipe from the cone to discharge the residual material contained
therein;
- open the valve inside the cone (using a suitable lever), to discharge any residual sewage
from the pump;
For all electric motor versions, after checking the correct direction of rotation, connect to
the power supply.
WARNING: before opening the delivery pipe, ensure that the system is not still un-
der pressure.
WARNING: never run the pump under no-load operating conditions, without filling
the cone (1 fig. 3) using the dedicated filling inlet (2 fig. 3).
If the vertical gap between the surface of the liquid and the suction cone is greater
than 3.5M, then use of the foot-valve is recommended (see "OPTIONAL EQUIP-
MENT" chapter).

7. WORKING AND SAFETY GUIDELINES
1) When working and carrying out inspections on the machine, wear appropriate cloth-
ing (overalls, gloves, helmet, safety shoes, fastened clothes, etc.), which have been
previously checked and approved by the site's safety manager. The machine should
be used in an adequately lit space.
2) Check that:
- the work area is adequately ventilated;
- there are no naked flames in the vicinity.
3) Never inspect the sewage tank alone. In the case of loss of balance or fainting due to
fumes, immediate assistance is required.
4) When you do not need to perform operations in the tank, it should remain covered.
5) Only suitably trained staff can use the machine and access the operating areas.
6) Do not perform repairs or adjustment operations when the machine is in operation or
when it is connected to the power supply.
7) The machine should only be used when all protective equipment is in place, follow-
ing the instructions identified in the above paragraphs in order to avoid contact with
moving parts. Do not damage or remove the protective equipment.
8) Never operate the machine without having filled the oil (transmission pipes and gear
units).
9) Prior to starting the work phases, ensure that the entire working unit (machine and
tractor) is stable.
10) During maintenance, ensure that the machine is completely at a standstill and dis-
connected from the power supply.
11) Do not use the truck for road transportation (if required).
12) During use, adjustment or maintenance, avoid the rubber parts of the machine
(gaskets, etc.) coming into contact with oil, grease or oil derivatives.
13) Ensure that the motor is rotating in a clockwise direction as indicated by the arrow
positioned on the motor (where appropriate).
14) For all electrically operated machines, the connection should be carried out in a loca-
tion protected from rainfall.
15) If the outlet is connected to pipes or hoses, check that the fixing joints are in perfect
condition; do not stand close to them.
16) Store the machine in a dry place, protected from rainfall, when not being used for
prolonged periods.
17) Never start the machine up under no-load conditions.

8. MAINTENANCE page 9
Before carrying out any maintenance operations, stop the machine and disconnect it
from the power supply.
1) Regularly check the oil level of the parts that require lubrication, (transmission pipes
and gear units). Replace the oil after the first 50 hours of operation and again after
1500 hours of operation (800 hours for the HD unit) or every year (use ISO VG150
oil).
2) Every 50 hours of operation, grease the rotating parts (lubricators, piston articulated
joints, toothed wheels, etc.).
3) Wash the machine after use to prevent the residual sewage from generating natural
gas (explosion risk) and to prevent corrosion damage.
4) Regularly check the state of wear of the blade and the rotor. If necessary, replace
them.
Contact DODA authorised dealers directly for all spare parts.
For pumps with the "IV" unit, it is recommended that the oil be replaced
after every 500 hours of operation.
Oil should be introduced into both the bell housing and the gearbox.
Warning!! If not enough oil is introduced, it will remain in the bell hous-
ing and the gearbox will not be properly lubricated.
WARNING!
To properly replace the oil in the "IV" unit, carefully follow the instruc-
tions on pages 10 and 11.
