PROTECTION SYSTEMS The Auto Reset protection systems (leaf spring or hydraulic) SHEAR BOLT Protection: In the SSF and SLF models, work automatically. When the share meets an obstacle the beam protection is achieved by means of shear bolts (Fig.2). When the trips up thus overcoming the obstacle and then returns back to its share point meets an obstacle, the shear bolt breaks and permits original position with no need to stop the tractor.

Once the working pressure is set, close valves. Note: The auto Reset systems from OVLAC are set at the factory for average conditions. In order to minimize impacts on both the tractor and the plough, we recommend to work at the lowest possible pressure.
4. SET TO WORK 4.1 ATTACHING THE PLOUGHT Before attaching the plough check the following points: The lift rods of the tractor must be set to the same length and height. The wheels of the tractor must have the same pressure and it must be set according to manufacturer´s instructions.
To detach proceed as follows: Lower the front part of the plough and act on the wheel so the tractor is lowered with the coupling bar in a horizontal position. In this way detaching as well as the next attaching will be much easier.
4.3 MOULBOARDS 4.4 FIRST FURROW WIDTH ADJUSTMENT Before starting work, the paint on the mouldboards should The first furrow width is adjusted hydraulically by means of the be removed to avoid that the soil remains adhered. In order to cylinder A (Fig.11). The longer the ram, the wider the first furrow. ease this operation, a special peel-off paint is applied at the factory.
4.5 ALLIGNMENT 4.7 WORKING DEPTH The working depth is adjusted hydraulically by means of the cylinder C During work, the plough must run straight and parallel to the working (Fig.13). The maximum working depth is adjusted by means of nut D on direction.
4.8 WORKING WIDTH The "S" series (SSF, SSB and SSH) features the OVLAC exclusive system to adjust hydraulically the furrow width – Varilabor - which allows to choose any working width between 12" (30cm) and 21" (53 cm) by means of the cylinder A (Fig.14). The direction of the wheel is adjusted automatically.
4.9 TURNOVER SYSTEM 4.10 OTHER ADJUSTMENTS The turning of the plow is achieved by acting on the telescopic Check that the beams work vertically with respect to the field. To hydraulic cylinders E (Fig.17). achieve this, make sure that the lifting arms of the tractor are set at the same length and act on the stop bolts A below the turn over rams (Fig.18) Fig.17 Fig.18...
TRANSPORT AND PARKING The stand P (Fig.20) guarantees a steady position when the This plough is transported in “butterfly position”. The valves V plough is parked. When parking the plough make sure that the locking pin of the stand is placed in the right hole so that he draw must be closed so that the turn over mechanism is locked (Fig.19).
6. MAINTENANCE Retighten all bolts and nuts after the first 8 hours of work, specially Take care of the leaks of high pressure the ones of mouldboards, shares and points. Henceforth, check every 100 The fluids that escape of the system can have as much force that hours of work.
Page 17
MAINTENANCE PLAN The points marked in Fig 21 must be greased with the following periodicity: 1- every 10 working hours 2- every 50 working hours 3- every 100 working hours As a general rule, all of these points should be greased before and after every season.
CONTENT HEADSTOCK ................. 20 8. SPARE PARTS TURNOVER CONNECTION ..........24 FOLK ..................26 Spare parts should always be ordered from your dealer and should always include the following indications: FRAME SS ................28 FRAME SL ................32 - Type, model and serial number of the plough. These data are punched on the identification plate with which every plough is equipped.
