Important: always works with a pressure in between 100 and 135 bars. NOTE: OVLAC Non-Stop security systems are regulated in factory with an optimum pressure for mid hardness terrains. IMPORTANT: always work with a pressure in-between 100 and 135 bars. Maximum working pressure is 140 bars.

4.- Turn Up - Linking and unhooking Before linking the plough check: Tractor arms are regulated at the same length and heigth. Tractor wheel must have identical pressure adequated to the manufacturer rules. Tractor arms must be centered with a slight margin for oscillating. In order to link follow the next steps: Fig.
Page 11
For unhooking the plough you must: - Hydraulic conections Place the pawn in P position (Fig.8). Lower the frontal part a bit (tractor's link elevator), and play with the wheel of the plough, place the plough on the In this type of plough, 4 double effect controllers are ground so the bolts of the shaft remain horizontal to the required for the next operations: ground.
Page 12
- 1st body width Adjustment The 1st body width is regulated standardly hydraulic through the cylinder A (Fig.11), The more retracted the cylinder gets, the more space between tractor and furrow. IMPORTANT: IT'S RECOMMENDED TO HAVE THE CYLINDER A ON ITS SHORTEST POSITION, AS INDICATED IN FIG.11 Fig.
Page 13
- Adjustment always out of the furrow The labor on this kind of ploughs demands to work out of the furrow, always acting over the cylinder B (Fig.12). which must be retracted to its working position and stretched to make the turning maneuver and also for the transport. This cylinder is connected in a sequential way with the opening cylinder of the rear part, so when one's stretched, the other is retracted.
Page 14
- Turn The turning of the plough it's made by acting hydraulically over the telescopic cylinders E (Fig.14), always must act previously on the cylinder B (Fig.12, pág. 12) this must be stretched for making the turning maneuver (aligning the most possible) diminishing the arm's pull as well as lowering the gravity center and prevent the overturning on the headstock's maneuver.

5.- Transport and parking TRANSPORT: This plough is transported in half-turning position. The valves V PARKING: The support pawn P (Fig.17), assure an static position must be closed to block the turning system (Fig.16 ), the cylinder B (Fig.12, pag. while parking.
6.- Maintenance Must check how tighten the bolts are after the first 2 hours of labor, Watch out for the high pressure leaks specially the ones on the skimmers and shares. Afterwards, check every 100 hours of labor. By finishing the campaign, wash the plough and grease the Leaking fluids from the system might leak strong enough to tear flesh, skimmers to avoid rust.
Greasing points Greasing points shall be greased every 10 hours of operation Not authorised use Placement of jacks For any manipulation of the tyres it is necessary to place the jacks in the places indicated on the axle of the machine, where the stickers indicate.
7.- Maintenance Plan Must grease the stand-out points indicated in the figure (Fig.19) with the next regularity: Every 10 hours of labor Every 50 hours of labor Every 100 hours of labor As a general rule, all this points must be greased before and after every campaign. IMPORTANT: check regularly the re-tighten of screws and bolts.
9.- Spare Parts Spare parts’ orders must be ordered through the distributor, and must always include the next directions: - Type, model, and manufacturing number, indicated on the nameplate. - Spare part’ reference number (indicated on the spare parts pricelist). - Name &...
