Page 19: Axle Loads
Preparation of the Tractor Axle Loads The attachment of implements to the front- and rear-three point linkage must not lead to exceeding the allowed total weight, the allowed axle load and the allowed tyre load of the tractor. The tractor front axle must always be loaded with 20 % of the tractor dead weight at minimum. -
Page 20: Use
General Instructions Before the first use it is recommendable - with fully lowered implement - to carry out the following adjustments at the farm. Afterwards only few adjustment correc- tions have to be carried out in the field. Top Link Connection Connect top link to headstock (1) and en- sure that the top link rises slightly towards the plough. -
Page 21: Adjustment Of The Outer Turnbuckle Of The Adjustment Centre Optiquick
Adjustment of the outer Turnbuckle of the Adjustment Centre Op- tiquick The outer turnbuckle (2) has been adjusted to the extreme to allow compact transport on lorries. Adjust this turnbuckle to a length similar to that of the main link (3). Final ad- justments can take place in the field. -
Page 22: Clearance For The Turnover Operation
Clearance for the Turnover Operation Check whether there is sufficient clearance between plough/depth wheel and ground. If not, shorten the inner turnbuckle (1), set drawbar deeper, fit top link to a higher hole in the headstock or use an hydraulic frame swing-in assy. -
Page 23: On The Field
On the Field Set tractor hydraulics to ‘Draft Control’ or 'Mixed Control'. Set in the plough and adjust the length of the top link, vertical pitch, front furrow width, working depth and depth control wheel / depth and transport wheel as re- quired. -

Page 29: Turning The Plough Frame
Turning the Plough Frame TURNING THE PLOUGH FRAME The turnover device is equipped with a double acting turnover ram (1) with auto- matic turnover valve and automatic lock valve for the connection to a double acting spool valve. In combination with a separate return pipe to the oil tank of the tractor it is possible to connect the turnover ram to a single acting tractor spool valve. - Page 30 Turning the Plough Frame − For the turning operation raise plough completly! − Switch control lever to "H": Plough frame turns through about 180° ! − After completion of the turnover opera- tion move the lever to the position ‘N’. After 3 - 6 seconds the next turnover can be started.

Page 37: Tractor/Plough Alignment
Adjustments Tractor/Plough Alignment Adjust the tractor/plough alignment by means of the inner turnbuckle (2), so that there is no lateral draw. Tractor pulls to the ploughed land => lengthen inner turnbuckle (2)! Tractor pulls to the unploughed land => shorten inner turnbuckle (2)! It is always positive to adjust the inner turnbuckle as short as possible (saving of turning energy, low oil heating, higher lift height, lower landslide wear and lower tractive-force requirement). -
Page 38: Angular Adjustment
Adjustments Angular adjustment 8.3.1 General information When ploughing, the base blade should be almost vertical to the ground as seen from the direction of travel. If this is not the case, then the angular adjustment must be altered as described below. 8.3.2 Angular adjustment (double acting) a) Raise plough by several centimetres (approx. -

Adjustments 8.3.3 Angular adjustment (single acting) In combination with a slewing cylinder (1) connected to a single-acting control unit with a return line to the tractor's oil tank, the angular adjustment is set as mentioned in points a) - c) of the previous section. Following this raise the plough completely, turn it all the way and then back again after approx. -
Page 40: Working Depth
Adjustments • Risk of crushing and shearing in the area between the stopper arm and the end stop! Keep to a sufficient safety distance! Working Depth The working depth adjustment occurs via the tractor hydraulics and the depth wheel of the plough.

Adjustments 8.6.2 Working Width per Body After the basic adjustment has been car- ried through by means of the OPTIQUICK- adjustment (Trulign), the working width per body can be adjusted from the tractor seat by means of a Memory ram (1) or an ad- juster ram (2). -
Page 44: Tail Pieces
Adjustments 8.6.3 Tail Pieces The tail pieces (2) being positioned at the end of the mouldboards (1) should be ad- justed so that they help to turn the furrow slice. They should be adjusted uniformly. Set too deeply, they can cause soil to fall back into the furrow. -

Adjustments 8.7.2 Angle Adjustment The angle of the skimmers which are fitted with their flat stalk (4) directly to the stalk bracket (5) or the beam of the X-ploughs, cannot be changed. Otherwise the angle is adjustable either − − − − variably by means of clamp screws with the skimmers with round stalk or −... -
Page 46: Conversion To The Front Or Rear
Adjustments 8.7.4 Conversion to the front or rear By means of re-positioning the skim stalk (4) or the bracket of the angle adjustment to the front or rear, the position of the skimmer (1) can be optimised. To the rear = more clearance between skimmer and the plough body fitted in front. -

Page 60: Operation
Overload Safety Devices 9.4.2 Operation During work the plough bodies will be kept in working position via the rolling sys- tem. When touching an obstacle the plough body trips upwards, therewith the oil will be led into the hydro-reservoir. If several bodies trip at the same time, the oil cannot be kept by the hydro-reservoir. -
