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.- Non-Stop Security Systems
“Non-Stop” Leafspring security system acts automatically. When the share meets an obstacle, the
systems gives up, elevating and saving the arm, getting back to its original position without stopping
the tractor.
This way, every impact caued by uneven terrain will be absorbed by the security system, which
protects the elements of the machine, and therefore, also the tractor.
For the same reason, Non-Stop security systems decreases the traction effort by avoiding the
tractor HAVING TO OVERCOME every obstacle and having an uniform labor.
In the machines equipped with leafspring securiry system . the string of the bow that determinate
the leafspring, must have a length of +- 500mm, measure as appears on Fig 2.
Note: OVLAC Non-Stop security system are factory-regulated witn an optimum pressure for
midhardness terrains.
