Due to the centre of gravity, the machine will lean about 55° while lifting it.
In order to make handling operations safely , always wear safety shoes and
make sure that there are no people or animals nearby while working.
- The machine must be transported by professional means of conveyance (trucks, vans, etc.).Do not
use carry the machine in a car. In all cases, before transporting the machine , make sure that it is well
anchored with straps and strings and that it is stable enough. The anchor points can be the roller
group support, the three point linkage pin, the coupling tractor arms and the roller support.
- Always check that any walkways, ramps, etc. that must be crossed are well anchored and have a
capacity capable of supporting the total load of the vehicle + machine + operator. When using ramps
for loading, ensure that the vehicle has the handbrake on and have been positioned the wedges
suitable for locking the wheels.

5 - Accident prevention
(*note 4 mod. hi)
Most accidents that happen at work, during the maintenance or the shifting of a
machine, are due to negligence in the observance of the most elementary rules of
accident prevention
It is, therefore, necessary that whoever uses the machine read and respect the rules written below
and the ones on the adhesive stickers of the machine.
1. Verify that on the machine are stuck all the security signs and that they are readable.
2. Before cleaning the machine, making any adjustments or reparations, turn off the tractor
engine. Before each operation put the machine on the floor or on steady supports.
3. Never approach to the machine moving parts
4. The STONEBURIER Mod. TST – TSThi has been manufactured for a specialized use. It
must, therefore,always be in perfect working conditions and only R2 spare parts should be
used when making any reparations.
5. Before using the machine , check the tightening of the nuts and screws, in particular those of
the hoes and the three point-linkage
6. Keep away all the people or animals before starting to work.
7. Be careful when working alongside roads, pathways or sloping ground.
8. Do not leave the machine working without supervision.
9. While checking or repairing the machine, be sure that nobody can start it up accidentally.
10.Wear tight-fitting clothes that do not cause any footholds in the rotating parts of the machine .
11.Do not climb on the machine at work.
12.Do not interfere with objects on the machine while working.
13.Never use the machine without the back roller or without the protections delivered with the

6.3 – Cardan shaft connection
Once the machine has been connected to the tractor, verify the exact length of the cardan shaft. For a
safety function of the cardan shaft, it is very important to check that in the different working positions
the drive hoses fit in half of their length and never less than 1/3 of their length (Fig.7); repeat this
control when the STONEBURIER is fitted to another tractor.
When fitting the cardan shaft, be sure that the bolt or push-button on both sides are well locked (Fig.9
- Ref.A).
Lock the cardan protections with the suitable chain to avoid them from turning during the motion drive
(Fig. 9).
To reduce the cardan wear ( and increase the length of life) limit the working angle maximum to 15°
(fig. 10).
Read carefully the cardan instruction booklet
before the connection. Make the operations
wearing appropriate protective devices for each
person.
-It is forbiddden to use the cardan without the protections It is necessary to replace the cardan
protections once they are worn out.
- In order that the cardan and their components last longer, when the machine is not working ,
anchor the cardan to the hook so that it does not touch the ground (Fig. 11 – Ref. A)
Cardan type: CE type 4 for nominal horse-power up to 35 HP at 540 r.p.m
The use of cardans with different characteristics than the ones supplied excludes the GUARANTEE
automatically.
ALWAYS USE CE CARDANS AND IN PERFECT STATE OF REPAIR

7 - Preparation for use
Before using the machine it is necessary to perform the following controls with the
tractor and the key off:
- Check the bolts tightening and that all the elements are in perfect conditions.
- Check that the security signs are present and legible.
8 - Working depth adjustment
(*note 6 mod. hi)
The working depth is adjusted by the screw crank register roller (Fig.12 - Ref.A). The roller must be
adjusted so that during the working the machine sides are leaned or inserted on the soil ( the inferior
side of the chain guard (Fig. 12-Ref. B) touches the soil.
In order to avoid dangerous situations, it is necessary that during the milling the sides
touch the soil.
9 – Levelling adjustment.
The levelling is made with the back shovel (Fig.12 - Ref.C); the scraper is adjusted manually with the
two special screws and depends on the working depth chosen (Fig.12 - Ref.D). For a good levelling
result, be sure that while working there is always earth in front of the scraper.
Adjust the scaper always with the tractor off and the key off. Wear protective
gloves to prevent injury to the hands skin.

10 – Machine use
(*note 7 mod. hi)
10.1 – Soil working
Once you have made the adjustments, it is possible to operate the tractor; the PTO will determinate
the hoes rotation . Pressing the forward, the working soil will start. The operator’s position is 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 tractor feed.
2. Stop the PTO motion.
3. Lift the machine using 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.
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 tractor instruction booklet ).
- Before operating the machine, verify that the safety system of the tractor
functions correctly
10.2 – Milling group
The Stoneburier Mod. TST – TSThi has been designed and constructed so as to minimize the
possibility that the milling group 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 stoneburier from locking, we advise to remove the big stones, the iron
wires, etc. from the surface before working.
To unlock the machine it is possible to do in the following way:
- Disconnect the tractor PTO.
- Lean the machine on the soil (lowering the lifting unit) and go some metres forward (with the
PTO disconnected) so that the milling group turns in the opposite way of the working sense.
If the machine blocks it is necessary to check the milling group. TURN OFF
THE TRACTOR ENGINE and REMOVE THE KEY. The key must be
kept by the person that will remove the stuff that has locked the
machine
To unlock the machine remove the stuff with a long shaped tool; do not use the hands.

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 screws tightening of the three-point linkage frame and the good state of repair of the
pins and the safety pins of the connection arms.
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.
- Regularly:
1. Lubricate the universal joint spider (Fig. 13 – Ref. A) and the other cardan elements as
indicated in the instruction booklet, through the greasers.
2. Lubricate the universal joint (Fig. 14-Ref. A) and the forks (Fig. 14-Ref. B) of the double joint
transmission each 50 working hours :
- At the beginning of the working season and each 4 months:
1. Check the level of the lubricant oil in the gear-box through the transparent cap put on the gear
box side (Fig. 15 – Ref. A); the quantity of oil is enough if it is visible through the cap. If you
need to fill oil up,use the cap put on the upper part of the gear box (Fig. 15 – Ref. B).
2. Grease the roller supports (Fig. 16 - Ref. A).
3. Check the grease level in the chain guard using the specially provided cap (Fig. 17 – Ref. A);
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 tractor off
and the key off.

12 - Hoes replacement
The hoes replacement must be made disassembling the roller group and the lateral protections
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. The hoes are important in the STONEBURIER TST-TSThi
because the depth of the stones burying depends on the hoes length. A higher consumption of the
blades reduces the working quality. Whenever you change the hoes use new nuts, screws and
bolts.
N.B. Use always original steel bolts.

5. Protect and lubricate all the metal unpainted parts, then cover the machine and keep it in a dry
place, it will be ready for use at any time.
Attention: Before using the machine again, refer to the “Maintenance” chapter.
Keep the machine in a way that people or animals do not run any risk (stumbling, machine falling
down) and protect the prominent parts in order that they do not cause injury.
To avoid danger situations, store the machine in a way that does not hamper the escape routes, the
emergency exits, fire protections (fire extinguishers, hydrants, etc.) and first aid (first aid boxes,
etc.) from the storage place.
If the washing and/or cleaning of the machine is made by compressed air
or water, be sure that there are no people or animals in the working area
and wear protective glasses and if necessary a dust mask. Do not direct
the jet of compressed air or water to people or animals
14 - Scrapping and disposal of the components and packaging
In case of machine scrapping, it is necessary to make it unusable to prevent that others can use it
again; the reuse of the machine by a third party, can be dangerous and accidents can be
prosecuted according to Civil and Criminal Procedure, under the laws in force in your country,
towards those that get rid of the machine without precautions.
In order to make the machine unusable, it is necessary to disassemble the pinion-hub and dispose
it separately from the rest of the machine
The machine is made of metal parts and of lubricant substances; they must be disposed in special
waste disposal centers.
According to the type of transport, the machine can be packed in a cardboard (box) wood (pallet)
plastic (polypropylene strapping and stretch film polyethylene) and metal (steel strapping seal or
wire if the machine is delivered directly on a pallet); these items must be disposed in special waste
disposal centers
The polyethylene stretch film must not be used as a children toy because it may cause
e
suffocation.
For the environment respect, dispose the materials in centers for separate rubbish.

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! the 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.
