SPECIFIC INSTRUCTIONS FOR
WELDING REPAIRS
When repair by welding is authorised by the manufacturer, the
following points shall be taken into account generally.
In particular cases, appropriate welding instructions shall be
provided for each application.
1 Repair welding should be carried out by qualified welders and
in accordance with good technical and safety code practice.
2 Before welding repairs, remove paint, rust, dirt or any other
substances harmful to the weld.
3 To avoid damage to mechanical or hydraulic components such
as bearings, shafts, hydraulic actuators, hydraulic systems, etc.,
care should be taken to place the earth connection in an area of
good contact, free of paint and rust.
On machines with hydraulic cylinders, we must ensure that the
welding current does not flow through such elements. For this
purpose, the earth connection shall be placed on the same part
of the machine to be repaired.
4 Our machines are made of high elastic limit (HEL) steels, which
means that special attention must be paid to welding processes
and filler materials. In general, basic coated electrodes E7016 or
E7018 will be used. For the MAG (semi-automatic) welding
process, ER70S6 wire and Ar+20C02 will be used as shielding gas.
In both cases, follow the recommendations for drying times and
temperatures recommended by the manufacturers of the filler
material.
5 When the parts to be welded are thicker than 15 mm, or the
ambient temperature is lower than 15 C, preheating by flame
between 75-100 C is recommended.
6 It is strictly forbidden to cool welding seams with water, air or
any other substance.
In case of questions during repair, please contact the
manufacturer via the usual means of communication.

3.- Varilabor
In the OVLAC XP models the working width can be adjusted up to the needs of the farmer, in 4 different positions divided by steps of 2" (5 cm). The
positions 1 and 4 answer to the minimum and maximum positions, respectively (Fig. 3). After changing the working width of the plough, you must
regulate the landslide extension of the plough through the memory cylinder (C) by adjusting the working measure as the sticker X indicates (Fig. 2).
Make sure that the allignement of the bodies coincide with the working direction.
XPV models incorporate the exclusive OVLAC control system of the fisrt body and variable cut –Varilabor-, which allows to adopt any working width
between 10” (30 cm) and 22” (55 cm), with a single operation directed over the cylinder C, even moving, from the tractor's cabin.
If the plough does not have an oscillating shaft available you must adjust the drifting through the tensor T (Fig. 1) until it matches the measure
indicated in the sticker (P).
The indicator points to the selected working width. The possibility of modifying the furrow width allows to adapt the plough to the terrain conditions
and the tractor's power.

4.- Security Systems
Shearbolt security systems warantee protection through its shearing bolts.
When the tip faces an obstacle, the bolt breaks, allowing the leg to turn on
its hosting. In order to continue the labor you need to place the leg again
and find a new replacement for the bolt B. (Fig. 4)
WARNING: Use only original shearbolts. Other kind of bolts will not offer the
same resistance, which can result in malfunctioning and therefore
cancellation of the warranty.
NOTE: size and quality of the shearbolts is calculated for them to break at a
determined pressure. Is essencial to replace the bolts with same-quality-
and-size bolts, otherwise you'll lose the warranty.
Hydraulic "Non-Stop" security systems act automatically. When the shear
faces an obstacle, the system gives up, allowing the leg to elevate and save
it, retrieving afterwards to its original position without stopping the tractor.
(Fig. 5)
By doing so, all the impacts made by uneven terrain are absorbed by the
security system, which protects all the elements of the plough, and of
course, the tractor.
For the same reason, "Non-Stop" security systems decrease the traction
effort by avoiding the tractor to face all the obstacles by itself.
Fig. 3
Fig. 5

Fig. 4 B

In the HYDRAULIC models, in order to adapt the plough to the conditions of
the terrain, you may regulate the trigger pressure by injecting (hard terrains)
or retiring (soft terrains) oil from the circuit and modifying the pressure in the
whole system. For regulating the working pressure you must:
-Open the key C (Fig.6) in order to read the pressure in the pressure gauge.
-Open the key L (Fig.6).
-Acting over the corresponding tractor command to increase o decrease
the pressure.
-Once the pressure is adjusted, close the keys L and C.
Note: The OVLAC Non-Stop security systems are regulated in-factory at an
optimum pressure for medium-hardness terrains. Always work with a
pressure in between 120 and 135 bars. Maximum working pressure is 140 bars.

5.- Turn Up
5.1 - Adaptation to the tractor
OVLAC ploughs are designed to be adapted to the three universal linking
points of any tractor.
The oscillating shaft, or linking rod, is supplied in 2 versions (distance
between centers):
CategoryII 890 mm.
Category III 1025 mm.
The linking rod must have the right length in order to make the pulling
forces converge at the center of the front axis, as displayed in the
Fig. 7.
11
Fig. 7
5.2 - Working bodies
Eliminate the layer of paint that protects the bodies before
working, in order to avoid sticky soil in your bodies.
Check that the distances A1=A2 and B1=B2 as shown on the
Fig. 6. If said distances doesn't match, adjust them through
the pulling C and the Bolts D and D'. (Fig. 8 and 9).
Fig. 8 Fig. 9

5.2 - Vertederas
5.3 - Alignment
The plough must work aligned with the tractor, if not, the plough will tend to
abandone the working direction. Must check that the distance A1=A2 (Fig. 7, page 11).
In the OVLAC ploughs, the drifting effect is auto-corrected thanks to the oscillating
shaft.
At ploughs with no oscillating shaft you must act over the tensor T of drifting
correction (Fig. 11) by making the rules on the sticker P.
The third point arm must be coupled in a way that, when on working position, the end
that links over the plough remains slightly higher than the end that links to the
tractor (Fig. 10).
The third point (EXCEPT TRACTORS WHOSE CONTROL IS ON THE THIRD POINT) must
always link the drill E (Fig. 10) trying that its length doesn't stop its free movement
throughout the whole labor.

5.4 - First furrow width
The first furrow width is adjusted acting over the tensor T that displays the headstock (Fig. 14)
in a way that verifies the observations described in Fig.13. If we stretch the Tensor we increase
the width of the first body and viceversa.
The plough counts with regulation possibilities conceived for a width between wheels of 110 to
200 cm, being optimal 120-180 cm.
As a starter point, after regulating the perpendicularity of the ANCHOR according to the terrain,
acting over the turning tops A (Fig. 17) we'll settle a working width of 40-45 cm and then we'll
place the point of the first body around 40 cm of the inside of the wheel as indicated on the
right image in fig. 13.
After, adjustments are meant to be made according to the wheel's width, speed, and terrain.
We don't recommend wheels over 710mm in order to work in-furrow.
Optionally, the width adjustment of the first body can be done from the tractor's cabin with the
hydraulic cylinder H (FIG. 12). If we stretch the cylinder we increase the width of the first body
and viceversa.

5.5 - Other adjustments
The length of the third point must be adjusted in a way that the
frame is parallel to the ground, otherwise the first bodies would
work at uneven depth compared to the last bodies, resulting in
uneven labor (Fig. 15).
For the same reason, you must check (while laboring) that the
anchors adopt a perpendicular position to the ground (Fig. 16). For
that, we need the tines of the tractor to be at the same height AND
ACT OVER THE TURNING TOPS (A) FOUND AT BOTH SIDES OF THE
HEADSTOCK (Fig. 17).
IMPORTANT: Must try not to drive over curves while laboring,
specially with long ploughs, since the pulling strength may cause
damage on both the tractor and plough structure.

6.- Working depth
The working depth is regulated through the lifting pull of the tractor. Nontheless, in order to obtain an even working width in order to save
power, all ploughs must be equipped with a depth-limiting wheel (Fig. 18) which height is regulated through the threaded tops A, as the figure 19
indicates. There is a relation between depth and working width that is convenient to respect in order to obtain the best results.
The board provides an excellent reference between working width and depth, which applied correctly it will turn out as great results.
We recommend to maintain the right pressures in order to extend the life of the wheel, as noticed on the last board.

7.- Wastes burial
16
For an optimal burial of harvesting leftovers and weeds we can equip the
plough with trashboards (Fig. 20) or the skimmers (Fig. 21). The trashboard can
be regulated in height according to the working depth, moving it along the
bracket slide.
The skimmers must be adapted to the working depth, acting over the bolts
that support it. As a reference, the share of the skimmer must dig in 10-12 cm
in the labor.
At the same time, in order to adapt the skimmer to different textures of the
terrain and working speeds we may set them in 2 positions (advanced or rear)
turning 180 degrees the bracket S (Fig. 22 and 23)

8.- Transport and parking
In order to ease the transport, the plough must be retracted to its minimum width, acting over the cut control system. Ploughs with great
lenghts (5 and 6 bodies) can be optionally given with polyvalent wheels of control/transport.
To transport the plough over the control/transport wheel, place the hole C in the position of the bolt B (Fig. 25). Pull the puller A of
the blocking headstock (Fig 24) so when the plough turns over it remains blocked in mid-turning position and block the oscillating
shaft with D bolts(Fig.24). Place the plough's wheel and unplug the tine on the third point of the headstock.
The support pawn (Fig.26), assures an static position of the plough on the parking.

9.- Maintenance
Must check how tighten the bolts are after the first 2 hours of labor, specially the
ones on the bodies and shares. Afterwards, check every 100 hours of labor. When
finishing the campaign, wash the plough and grease the bodies to avoid rust.
Lubing: must grease regularly the turning points based on the ambiental
conditions, both dust and humidity, to assure that no waste of the machine happens.
In the reversible ploughs its recommended to grease, if the greasers allow it, once
per each hand (clockwise and counter-wise), assuring that the grease, affected
by gravity, it extends for the whole turn and not just from the greasing point to below.
Safe maintenance
Get familiar with the maintenance proccedures before doing any labor.The working
area must be clean and dry. Not doing any greasing labor, repair or adjustment while
the engine is running. Keep the hands, feets, and clothes always far from the moving
components. Place all the hydraulic controls on neutral-gear in order to relieve
pressure. Lower all gear to the ground.
All the components must be in good shape and correctly installed. Repair damage
immediately. Change any wasted or broken piece. Keep all the components of the
machine clean off of grease, oil and accumulated dirt.
By dealing with trailed equipment, disconnecting the group of cables from the tractor
before doing any wielding on the machine.
Watch out for the high pressure leaks
Leaking fluids from the system might leak strong enough to tear flesh,
causing severe injuries. Therefore, is indispensable to leave the system
pressure-less before loosing or disconnecting any pipe and assure that all the
connections and connectors are well-tighten before applying pressure to the
system. In order to locate an hydraulic oil leak use a piece of cardboard
placed in between the connections. Don't get near high-pressure leakings.
Even if after all this measures an accident happens, go immediately to see a
doctor, who should remove the fluid surgically in a few hours in order to avoid
gangrene. Unexperienced doctors with injuries of such nature may go to a
specialized medical center.
Maintenance of hydraulic cylinders. IMPORTANT: keep the plugs clean.
Abrasive particles, such as sand, metal sharps, may damage the cylinders,
causing inner leaks. Once unplugged off the tractor, place the protection bolts
and make sure they're not touching the ground.
