OPERATING INSTRUCIONS AND SPARE
PARTS

2
This handbook describes the use, maintenance instructions
and spare parts supplied for the indicated plough.
The farming implement known as “plough“ is designed to
work the soil, linked to a tractor with lift and universal 3-point
coupling.
Regular and satisfactory operation together with economic
and long lasting use of the implement depends on compliance
with the instructions given in this handbook. It is, therefore,
advisable to strictly comply with the following instructions in
order to prevent faults which could jeopardise the correct and
long-lasting operation of the implement.
Compliance with the instructions in this handbook is also
important
since the Manufacturer declines all and every
responsibility caused by negligence and failure to comply
with these instructions.
The Manufacturer shall, however, remain at the customer’s
disposal for immediate and thorough assistance together with
anything else that may be required in order to ensure the correct
operation and maximum efficiency of the implement. The
Manufacturer reserves the right to make any modifications and
improvements to the implement, as may be considered
opportune, without being obliged to immediately inform the user.

3. SISTEMAS DE SEGURIDAD NON STOP
The Auto Reset protection systems work automatically. When
the share meets an obstacle the protection system pulls the beam
up (Fig. 2) thus avoiding the obstacle and returning to its original
position afterwards with no need to stop the tractor.
This way all the impacts produced by an uneven field are
absorbed by the protection system thus protecting all the elements
of the plough and of the tractor too.
For the same reason, the Auto Reset protections decreases
the traction effort by not making the tractor overcome every
eventual obstacle.
- SERIES MINI:
In heavy duty conditions one or more leafs can
be added to ease penetration of the plough. Always check that the
distance of the arch of the spring is 500 2mm (Fig. 3).
Note
: The Auto Reset systems from OVLAC are adjusted
at the works at an optimal pressure for average conditions.
Always work with a pressure of between 100 and 135
bars

4. SET TO WORK
4.1 –MOULBOARDS
Before starting work, the paint on the mouldboards should be
removed to avoid that the soil remains adhered.
4.2 –HITCHING TO THE TRACTOR
The OVLAC ploughs are designed to fit to the 3-point universal
coupling of any farming tractor.
The cross shaft can be supplied in two different lengths (centre
to centre):
Category II 900 mm.
Category III 1.000 mm.
The cross shaft must have the appropriate length to make the
drawing powers converge in the centre of the frontal axle, as shown
in (Fig. 5).

Fig.5
4.3 –ALIGNMENT
The plough should always work in line with the tractor. If not, the
tractor will tend to leave the furrow course. Check that lengths A1=A2
(Fig. 5)
Crabbing is corrected automatically in OVLAC ploughs thanks to
their oscillating cross shaft. In ploughs with fix coupling, act on the
drifting-correction turnbuckle (hydraulic in option).
The third point should be linked so that the end linked to the
plough be slightly higher than the one linked to the tractor (Fig. 6)
The third point should always be placed in the oblong hole E (Fig.
6), trying that its length does not hinder it to move while working.
4.4 –OTHERS ADJUSTMENTS
The length of the third point should be adjusted so that the frame
works in a parallel position with respect to the field since, if not, the first
bodies would plough at a different depth than the rear ones achieving
an uneven labour (Fig. 7).
For the same reason, check that the beams work vertically to the
field (Fig. 8). To achieve this, make sure that the lifting arms of the
tractor are at the same height and act on the adjusting bolts A at the
headstock (Fig. 9).

6. TRANSPORT AND PARKING
In order to ease transport, the plough should be drawn to its
minimum width by means of the width control system (turnbuckle or
hydraulic cylinder), Fig.10.
The stand P guarantees a steady position when the plough is
parked.
Fig.9
Fig.10
5. PLOUGHING DEPTH
The ploughing depth is adjusted through the hydraulic lever of the
tractor. Nevertheless, obtain an even depth, all ploughs can be
equipped with a depth control wheel (Fig.10) whose height is adjusted
by the bolts.
There is a relation between depth and width which should be
respected in order to achieve a good result.
The following chart gives an excellent reference which, if complied,
will lead to satisfactory results.

7. MAINTENANCE
Retighten all bolts and nuts after the first 8 hours of work, specially
the ones of mouldboards, shares and points. Henceforth, check every 100
hours of work. When putting the plough away, clean and grease
thoroughly the mouldboards to prevent from rusting.
Lubrication: grease the greaser.
Safe maintenance
Be used to the maintenance procedures before carrying out the
works. The working zone must be clean and dry. Don’t carry out any work
of lubrication, repair or adjust with the motor enabled. Keep the hands,
feet and clothes always far from movable components. Turn all the
controls off, to alleviate the pressure. All the components must be in good
state and correctly installed. Repair damages immediately. Change any
worn away or broken pieces. Maintain all the components of the machine
clean of fat, oil and accumulated dirt. Because of being dragged
equipment, disconnect the cable groups of the tractor before making
works of weld in the machine.
Take care of the leaks of high pressure
The fluids that escape of the system can have as much force that
they can penetrate the skin, causing serious injuries. Therefore, it is
essential to leave the system without pressure before relaxing or
disconnecting any pipe and make sure that all the connections and the
hydraulic parts they are well tight before applying pressure to the system.
In order to locate a hydraulic oil leak, use a piece of cardboard that is put
on the connections. Do not approach the hands and the body to a leak of
high pressure. If, in spite of this precaution, it happens an accident, go
immediately to a doctor who should eliminate surgically the fluid within few
hours to avoid gangrene. The doctors who do not have experience in
dealing with these type injuries can go to a specialized medical centre.
Storage of the hydraulic sleeves.
IMPORTANT:
maintain the plugs clean. The abrasive particles, like
the sand or the metallic shaving, can damage the oil seals, shirts and
cylinders, causing internal leaks. Once disconnected of the tractor, make
sure that they are not in contact with the ground

9. SPARE PARTS
Spare parts should always be ordered from your dealer and should
always include the following indications:
- Type, model and serial number of the plough.
These data are
punched on the identification plate with which every plough is equipped.
- Code number of the required spare part.
This will be found in the
attached spare parts list.
- Description of the part and required quantity.
- Means of delivery
. Transport expenses shall always be at the
consignor's charge.
- NOTE: The terms Right and Left
indicated on the descriptions, refer to
the plough when viewed from the rear. The spare parts components of
waste equipment, as shares, mouldboards, etc., are considered right if
they are mounted on a body which spills the soil to the right side and
viceversa.
- Note about the warranty
: The orders of spare parts in warranty should
always be clearly specified.
The Manufacturer will always sentence if
the spare parts are warranted in their replacement.
- Moreover, the warranty is suppressed if:
- The plough is repaired without authorisation from the
Manufacturer, or spurious spare parts, and inadequate bolts are
mounted.
-
The plough has been used beyond the specified power limit, or
anomalous manoeuvres and operations have been made.
