4.5. CHECKING THE TRACTOR LIFTING FORCE AND STABILITY
When an extra machine is added to the tractor, becoming a part of the tractor itself, as far as road circulation
is concerned, stability is different and driving and working become more difficult.
Depending on the composition of the machine, it is therefore advisable to add ballast to the front part of the tractor so
as to adequately distribute the weight on the axles.

On the front bridge of the tractor it must, in any case,
burden at least 20% of the total mass tractor-tool in march
order. It is how ever to hold present that, beyond to the
appropriated one chosen the connection tractor-tool, the
application of ballasts in front position, the limits and with
the modalities indicated from the constructor of the tractor,
can improve of the stability . Moreover, with firm tractor it
must be made to come down to earth the too lavoiding the
ref ore possible in voluntary reductions, improving at the
same time, the stability .

4.7. HYDRAULIC CONNECTIONS TO THE TRACTOR
The good performance of the implement depends largely from its correct use and from a regular maintenance program.
It is therefore advisable to follow carefully what is described in order to prevent any trouble which may impair the
performance of the machine and shorten its lifespan. It is also important to comply with the rules contained in this
manual, since the Manufacturer disclaims all responsibility for damages due to negligence or the non-observance of
said rules.
1. Connect the quick-plug of the hydraulic circuit to a socket of the tractor
( a pressure between 160/190 bar is required);
2. Gradually put the hydraulic system under pressure - shown by the manometer -
until the working pressure necessary for your particular type of soil is reached
Suggested pressure = 80/100 bar (see chart 5.5)
Remove the two pins from the side shaft support B and place
them in their correct place in the tractor connections A

5. USER INSTRUCTIONS
Follow all the safety regulations described in section 3 of this manual and consult the
documentation regarding tractor use carefully.
When the machine is connected to the tractor, activate the lifting
device then raise the support leg as indicated in the diagram
(do not move machine while leg is in resting position).
5.1. USE WITH TRACTORS EQUIPPED WITH CONTROLLED LIFTER STRESS
Start working by moving forward at a slow speed and lowering the shanks slowly until you reach the working depth needed.
Select working speed according to the soil and the power you have, keeping in mind that the faster the speed forward, the better
the soil breaking effect is.
5.2. USE WITH TRACTORS WITHOUT CONTROLLED LIFTER STRESS
If you are working with a tractor that does not have a controlled lifter stress device, the working depth can be regulated with the
right accessories that can be supplied upon request, such as a SET OF FRANTER ROLLERS or a set of rear wheels.
These accessories support the machine and regulate the working depth. It is advisable to start working at minimum depth then to
lower gradually until you reach the required working depth.
5.3. HYDRRAULIC OPERATION
The SKAT K1 – K2 series hydraulic subsoilers come with a cylinder hydraulic system. The single-acting cylinders work on the
shanks, lifting them while working (when there is an excessive force) and immediately repositioning them when the obstacle has
been passed.

5.4. SPECIAL VALVE OPERATION
This hydraulic device (ref. V) makes it possible to send to the accumulator A
the oil of the pistons of the shanks which are working under particularly severe
conditions.
Under extreme conditions, should all the shanks of the implement kick back at
the same time, a pressure of over 180 bar (max. service pressure in the
accumulator) would suddenly build up. In this case the valve will discharge
through the transparent tube T the quantity of oil necessary to keep the pressure under the maximum level allowed.
Above the valve there is a manometer M which shows the actual pressure in the
circuit.
Underneath there is a valve of max. pressure E, already calibrated at 180 bar to
guarantee the safety of the entire circuit.
The working pressure is adjusted directly from the tractor through its hydraulic
distributor.
In order to disconnect the hydraulic hose P for the connection to the tractor
hydraulic system it is necessary to eliminate the pressure from the
quick-coupling plug by shutting off the tap which is mounted at the end.
When storing the implement it is necessary to insert the pins into the
supports of the front shanks when these are in the idle position (see sticker).
While operating with the implement frequently check on the manometer M that the working pressure is of 80 bar.Should a
decrease caused by excessive stress occur, it is mandatory to restore the pressure by supplying more oil from the tractor.
5.5. VALVE SETTING – ACCUMULATOR SETTING
The working pressure of the shanks can be adjusted directly
from the tractor by acting on the distributor.
The recommended pressure is shown on the sticker -
reproduced here at the side - which is applied on the
accumulator .
This pressure is correct for working in medium-hard soils at
medium working depths.
Should the working conditions be different, it is possible to
increase or decrease the working pressure through the tractor
distributor, although remaining within the following range of
values: min. 70 bar, max. 110 bar.
(●) Recommended working pressure

5.6. MECHANICAL SAFETY
As well as being equipped with a
hydraulic safety device, each
machine shank has a bolt that
breaks by traction each time there
is a force above the machine
capacity. This safeguards
machine structure from excessive
forces. In addition, to guarantee
structure resistance, do not make
turns and do not change direction
while shanks are underground
because you would modify the
safety devices effect.
5.7. END OF SEASON OPERATIONS
If the machine is not used for long periods, the following operations should be carried out to maintain integrity
of parts of parts and machine:
•Lower supporting leg and lock it with the pin.
•Insert safety pins in the shank lateral supports as shown in pos. B(see section 4.2).
•Depressurise the hydraulic system (see section 5.4).
•Separate the tractor and the subsoiler.
•Wash machine carefully, then dry it.
•Make sure that the machine is in perfect condition.
•
Protect all unpainted metal parts with lubricants, then cover the machine or place it in a dry area.
The ground should be solid to guarantee machine stability. It is an advantage for you to find machine ready for use.

6. MAINTENANCE
6.1. CHECKS AND CONTROLS
During the first 50 working hours it is a good idea to check the tightness of all the bolts, because the power generated while
working creates structure movement. If necessary, tighten as indicated in the chart below.
Repeat this operation on a regular basis, every 200 working hours.
