6- Components assembly and coupling of the working equipment.
(*note 5 mod. hi)
Note: all the components that make part of the machine and that must be assembled before using it,
have been designed to minimize the user’s work ; the parts should be assembled using hand tools
(wrenches).
The assembly must be made on a steady surface or on an
homogeneous level floor. During the assembly wear
leather gloves and accident-prevention shoes.
6.1 Roller group and roller adjustment rod assembly.
Put the roller group screwing the two arms (Fig. 5 – Ref. A) in the holes that you will find in the back
part of the power harrow. (Fig. 5 – Ref. B).
Screw the roller adjustment rod (Fig. 5 – Ref. C) in the points indicated on the roller support (Fig. 5 –
Ref. D ) and in the power harrow (Fig.5 – Ref. E).
NOTE: the screws used to fit the roller group and the roller adjustment rod must be well tightened in
order that all the elements can turn during the adjustment.
6.2 Flange assembly and coupling of the machine to the walking tractor or tractor.
Before fitting the machine flange (Fig. 5 - Ref. F), which varies according to the model of the walking
tractor, we advise you to apply some grease on th external diameter of the machine hub (Fig. 5 -
Ref. G) in order that the machine oscillates . Fit in the flange with two special screws (grub screws)
(Fig.5-Ref. H) and two muts; in order to fix the flange on the hub do as follows:
- Screw the grub screws completely and then turn back of one turn, close the nuts and tighten.
Once you have finished, check that the flange oscillates freely without tightening or seizing,
otherwise repeat all again.
- Put the transmission sleeve (Fig. 5 - Ref. I) on the machine shaft previously lubricated.
Afterwards, bring the walking tractor near to the machine paying attention that the sleeve
engages with the connecting-shaft of the walking tractor and that the two flanges, the one of
the walking tractor and the one of the machine, fit perfectly well; then tighten the machine
with the rods of the walking tractor or tractor.

7 – Preparation for use
Before using the machine it is necessary to perform the following controls with the
walking tractor or tractor off and the key off:
- Check that the lubricant is at the indicated level.
- Check the bolts tightening and that all the elements are in perfect conditions.
- Check that the signs security are present and legible.
8 – Working depth adjustment
(*note 6 mod. hi)
The working depth is adjusted by the roller support pin (Fig.6 - Ref.A); choosing a hole on the rod the
working depth can vary from 0 to 14 cm. It is important that while the operator works, lthe machine
leans on its roller.
To transport the machine applied to the walking tractor, use the first hole of the adjustment rod
(maximum extent of leverage); in this way the power harrow will not touch the soil and the roller will
function as a wheel.
In order to prevent the hoes from remaining exposed and to avoid any
dangerous situation during the milling, it is important the the extension
sides (Fig. 6 – Ref. B) are adjusted in such a way that they always touch
the soil; the extension sides adjustment must be made with the walking
tractor or the tractor off and the key off.
9 – Levelling adjustment
The levelling is made with the front shovel (Fig.6 - Ref.C); the scraper is adjusted manually with the
two special screws and depends on the working depth chosen (Fig.6 - Ref.D). For a good levelling
result, be sure that while working there is always earth in front of the scraper.
In order to prevent the hoes from remaining exposed and to avoid any dangerous
situation during the milling, it is important that the scraper is adjusted in a way that it
touches lightly the soil surface.
Adjust the scaper always with the walking tractor or tractor off and the key off.
Wear protective gloves to prevent injury to the skin of the hands.

10 – Machine use
(*note 7 mod. hi)
10.1 – Soil working
Once you have made the adjustments, it is possible to operate the walking tractor (or tractor) and so
the PTO that will determinate the hoes rotation . Pressing the forward, the working soil will start. The
operator’s position is at the rear of the walking-tractor (or semi-laterally where it is possible to adjust
the handlebars) or at the driver’s tractor seat.It is important to remember that while driving you
should not make any turning maneuvers (the hoes are inserted into the ground) but only small
corrections of direction.
To change direction do as follows:
1. Stop the motion of the walking tractor or tractor feed.
2. Stop the PTO motion.
3. Lift the machine using the walking tractor handlebars or the tractor lift group.
4. In order to change direction, place yourself in the track you would like to follow.
5. Lower the machine
6. Operate again the PTO motion.
7. Operate again the forward motion.
Keep in mind the rules for the prevention of accidents mentioned in Section 5.
5. Always remember to:
- Keep away people or animals from the working area; do not allow anyone to aprroach to the
machine while working.
- Never approach to the mecchanical moving parts; wear safety shoes. If while working, there is a lot
of dust (which will depend on the type of soil) wear a dust mask.
- Do not use the machine in reverse; do not use the machine on steep slopes
(verify the walking tractor or tractor instruction booklet ).
- Before operating the machine, verify that the safety system of the walking
tractor or tractor functions correctly.
10.2 – Power harrow locking
The MILL GRADER Mod. MT – MTL – MThi – MTLhi has been designed and constructed so as to
minimize the possibility that the mill grader can lock while working.
. It is not excluded, however, that this can happen if there are stones or big stones, iron wires or
other elements that can fit in or roll in the hoes. In order to avoid the power harrow from locking, we
advise to do as follows:
-Before starting to work, remove the big stones, the iron wires, etc. from the surface .
-Adjust the working depth needed.
-Replace the hoes when they are worn out (see paragraph12)
If the power harrow locks, before making any adjustment , TURN OFF
THE ENGINE of the walking tractor or tractor and REMOVE THE KEY.
The key must be kept by the person that will remove the stuff that
has locked the machine.
To unlock it, remove the stuff with a tool of lengthened shape; do not use the hands. NOTE: usually
the machine is unlocked when the walking tractor or tractor engine is turned off as there is no
pressure in the hoes that keep the blocking piece.

11 - Maintenance
(*note 8 mod. hi)
Operations to be carried out in order to maintain the machine in good working conditions:
- Before using the machine:
1. Check the clamping of the walking tractor tie-rods on the machine flange.
2. Check that the screws are tight, in particular check that the hoes screws are intact, if while
working they break, it is necessary to stop working and replace them.
- At the beginning of the working season:
1. Grease the flange using the appropriate greaser (Fig. 7 Ref. A).
2. Check the grease level in the tank using the specially provided cap (Fig. 7 – Ref. B); this
must be made when the machine has worked for several minutes.
During the maintenance operations wear protective gloves; for the
lubrification/greasing operations always wear nitrile gloves and protective glasses.
If the maintenance is made on a raised plane (for example on a workbench), always wear safety
shoes.
All the maintenance work must be performed with the walking tractor or tractor off and the key off.
After finishing the lubrification/greasing operations, clean the residual of lubricant left on the floor.

12 – Hoes replacement
The hoes replacement must be made disassembling the roller group and placing the machine on
the back side so that the hoes are parallel to the ground. Place the machine on a stable and safe
plane. When mounting the new hoes, be sure that the clamping nut fits well in its seat (Fig. 8 Ref.
B); It is necessary to use new nuts, bolts and washers each time the hoes are replaced. N.B. Use
always original steel bolts. In order to use the hoes as much as possible, the machine has on the
sides two extensions(Fig. 6 - Ref. B), this allows to work even if the hoes are worn out, the
consumption must not exceed the 2/3 of the hoe itself.
N.B. For low-powered walking tractors (8-10HP) check that the PTO height from the ground is at
least 28-30 cms. If the height is of 25-26 cms. it is necessary to replace the hoes with shorter ones in
order that the machine is in-line with the walking tractor or tractor.
Fig. 8
While replacing the hoes, wear protective gloves. If the maintenance is made on a raised
plane, always wear safety shoes.
All the maintenance work must be made with the walking tractor or tractor off and the key off.
If the tightening of the hoes screws is
made with pneumatic screwdrivers,
put on ear protections and protective
glasses.

For the hydraulic machines, it is important to consider the following rules to pevent
accidents:
- Caution: the hydraulic system is under pressure.
- Before connecting a hose to the hydraulic circuit of the tractor, be sure that the circuits side
of the tractor and side of the machine are not under pressure.
- The pipe connections are protected by rubber stoppers, to prevent foreign bodies from
entering. When the Mill Grader R2 is disconnected from the tractor , it is recommended to
place the protective taps on the pipe fittings. When the Mill Grader R2 is connected to the
tractor, the caps remain attached through a ring to the hoses, so that they can be repositioned
next time.
- Check regularly the hydraulic hoses! Ithe damaged or worn out must be replaced
immediately. The new ones must have the specifications and the quality required by the
constructor(contact our technical service).
- If there is a leak, you must repair it immediately to avoid accidents.
- All the liquids under pressure, especially the hydraulic circuit oil , can cause serious skin
accidents!In case of wounds, go immediately to the doctor: there can be risk of infection!
- Before working on the hydraulic circuit, lower
the machine, remove the pressure from the
hydraulic circuit, stop the tractor and remove
the key from the console .
- In case of repair or work wear nitrite gloves and
protective glasses.

General rules for the hydraulic motor use:
- Working oil temperatures in the hydraulic system should be kept between +30°C and +60°C. The
anti-wear and lubrication properties of the oil are greatly reduced at higer temperatures.
- The ambient temperature around the engine should be between -30°C and +90°C
- Only use an oil containing antiwear additives ISO 46 or with a viscosity at normal operating
temperature of approx. 37 cSt, it should also have an adeguate viscosity index. Under no
circumsances should oil viscosity be outside the range of 22 cSt to 75 cSt.
- Before starting the hydraulic system check oil level and firm mounting of all components.
- Run the system unloaded for 10÷15 minutes to purge air from the circuit to prevent foaming and
deviation.
- Check for leak, rectify and refill reservoir
- Check oil level regularly and clean filters or replace them according to filter manufacturers advice
For maximum life from motor oil contamination shoul never exceed the 20/16 (see ISO 4406).
To ensure this level, return line filters should maintain 40 µm absolute or 25 µm nominal in open
circuit, 20 µm absolute and 10 µm nominal in closed circuit.
