3.- Security Systems Shearbolt security systems warantee protections 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.

Once the pressure is adjusted, close the keys A and C. Fig. 4 NOTE: The OVLAC Non-Stop security systems are regulated in-factory at an optimum pressure for medium-hardness terrains. Always work with apressure in between 120 and 135 bars. Maximum working pressure is 140 bars.

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, pág. 10). In the OVLAC ploughs, the drifting effect is auto-corrected thanks to the oscillating shaft.
- 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. 12) which height is regulated through the threaded tops A, as the Fig.
- 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. 14). Fig.

5.- Turn up - Turning and memory The turning point of the plough is done from the tractor·s cabin, acting in a programmed way over the corresponding hydraulic controller up to the end of the turn - This is made by turning always to the same side. Ploughs with 5 or more bodies standardly incorporate an hydraulic memory that aligns the plough automatically, turnit y and give it back to the working position prior to the turning maneuver when acting continously over the corresponding hydraulic controller.

- Varilabor In the OVLAC Series L 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. 16). 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.
Page 17
- 1st Furrow width The first furrow width is adjusted acting over the tensor T that displays the headstock (Fig. 19) in a way that verifies the observations described in the Fig. 21. The plough counts with regulation possibilities conceived for a width between wheels of 110 to 150 cm.
Page 18
- Perpendicularity of the plough working For the same reason, you must check (while laboring) that the anchors adopt a perpendicular position to the ground (Fig. 22). 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.
Page 19
6.- Wastes burial For an optimal burial of harvesting leftovers and weeds we can equip the plough with trashboards (Fig. 24) or the bodies (Fig. 25). The trashboards can be regulated according to the working depth, scrolling it over the holder's slider. The skimmers must adapt to the working depth acting over the bolts that supports them.
Page 20
7.- 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 B of the bolt C (Fig.
8.- Maintenance Must check how tighten the bolts are after the first 2 hours of labor, specially the Watch out for the high pressure leaks ones on the bodies and shares. Afterwards, check every 100 hours of labor. When Leaking fluids from the system might leak strong enough to tear flesh, finishing the campaign, wash the plough and grease the bodies to avoid rust.

9.- Optional Gear L and S OVLAC ploughs can be equipped with: Trashboard (Fig. 31) Landslide extension (Fig. 32) Transport wheel (Fig. 33) Discs (Fig. 34) Advanced wheel (Fig. 35) 1st body hydraulic width (Fig. 36) Fig. 36 Fig. 31 Advanced Transport wheel (Fig.37)
10.- Spare parts Spare parts orders must always be placed through dealers and will include the next indications: - Type, model and plough's number of manufacturing. This data is indicated on the identification plate of the plough. - Reference of the piece. Indicated on the spareparts catalogue. - Name of the piece and quantity required.
