Putting into operation Putting into operation This chapter provides you with information for putting your machine into operation. Before starting to operate the machine the operator must have read and understood the operator’s manual. When hitching the machine on and off, observe the chapter "Safety advice for the operator", page 23.
Putting into operation Initial operation 8.1.1 Calculation of the payload Payload [kg] = permissible total weight [kg] – empty weight [kg] The empty weight depends on the relevant equipment of the trailed sprayer. The empty weight of the complete trailed sprayer is deter- mined by the empty weight of the base machine (please see type plate) and the weights of the individual components (see "technical data").
Putting into operation 8.1.2 PTO shaft Only use the supplied PTO shaft Walterscheid WWE 2280. This PTO shaft is suited for driving bends in the field with- out stopping the spraying operation (observe the max. PTO shaft angling advice of the manufacturer). Important Maintain the permissible PTO shaft rev.
Putting into operation 8.1.2.1 First fitting and matching the PTO shaft At the initial coupling match the PTO shaft to the tractor accord- ing to Fig. 93. Any matching up refers to only this one type of tractor. When changing the tractor the length of the universal joint shaft should be checked again.
Page 102
Putting into operation 8. Apply grease to the sliding profiles and slide them into each other. 9. Affix the stop chain in such a way that a sufficient manoeuvrability of the PTO shaft is allowed in all normal operational posi- tions.
Putting into operation Hitching up Allow nobody to stand between tractor and implement while the tractor is backing up. Any assistants may only stay at the side of the tractor and Danger the trailed sprayer and help to direct it. Only when the vehi- cles have come to a full standstill they are allowed to step between them for the actual coupling procedure.

Putting into operation Supply lines between tractor and trailed sprayer 4. Couple the supply lines between tractor and trailed sprayer. Brake axle with air brake system 4.1 Coupling claw of brake hose (yellow). 4.2 Coupling claw of second hose (red). Before coupling the brake or second hoses ensure that the seal rings of the coupling claws are in perfect condition.
Putting into operation Various 5. Before the first daily travel drain the air reservoir. 6. Remove chocks, deposit in the retainers and secure. 7. Release the parking brake. Not releasing the parking brake would cause damage on brakes and/or tyres and a dangerous driving behaviour. Important 8.
Putting into operation 8.3.1 Manoeuvring with the unhitched trailed sprayer Air brake system Special care is imperative when manoeuvring with released ser- vice brake as only the towing vehicle would now brake the field sprayer. Danger Ensure that the trailed sprayer is connected with the towing ve- hicle before activating the release valve on the brake valve of the trailed implement.
Putting into operation Initial operation with the service brake system Carry out a brake test with the empty and loaded trailed field sprayer to check the braking behaviour of tractor and coupled field sprayer. Important For an optimum braking behaviour and a minimum wear of the brake lining, we recommend the re-adjustment of the coupled tractor and trailed sprayer by an authorised workshop (please see chapter "Maintenance").
Putting into operation Preparing spraying operation Pre-condition for an appropriate application of plant protec- tive agents is a trouble-free operation of the field sprayer. The field sprayer should be regularly checked on the test bed. Remedy possibly existing faults immediately. Important Use all designed filters.
Putting into operation 8.7.1 Preparing the spray mixture Implicitly wear protective gloves and relevant protective cloth- ing. The highest risk to be contaminated by the spray agent pre- vails when mixing the spray agents. Warning Besides the general hints listed up here, please also adhere to the product specific procedures, described in the instruc- tions for the plant protective agent.
Putting into operation 8.7.1.1 Calculating the filling or refilling quantities For the calculation of the required refilling amount for the previ- ous spray agent tank filling, use the table "Filling table for left over areas", page 111.

Putting into operation Filling with water When filling observe the permissible payload of your field spray- er. When filling your field sprayer carefully bear in mind the dif- ferent specific weights [kg/l] of the individual liquids. Important When filling via the suction port (chapter 7.7) implicitly open the lid of the spray mixture tank.
Putting into operation Inducting spray agents For inducting spray agents wear the protective clothing pre- scribed by the plant protective agent manufacturer. Warning Usually the agitation remains engaged from the time of fill- ing until termination of the spraying operation. Please ob- serve the advice of the spray agent manufacturer.

Maintenance, repair and care work Maintenance, repair and care work The following will provide you with information regarding cleaning, maintenance and repair work on the trailed sprayer. Precondition for the efficient operation of the trailed sprayer is carrying out mainte- nance work in regular intervals according to the check list mainte- nance work.
Maintenance, repair and care work Cleaning The regular cleaning of the trailed sprayer is the pre- condition for the appropriate maintenance and eases the operation the sprayer. Regularly check the field sprayer for corrosion. Monitor Important brake-, air- and hydraulic hoses with special care. Grease the trailed sprayer after any cleaning work, particu- larly after cleaning with a high pressure / steam jet cleaner or fat soluble agents.

Maintenance, repair and care work Air reservoir Daily drain the air reservoir. Fig. 118/... (1) Air reservoir. Important (2) Tensioning straps. (3) Drain valve. (4) Inspection port for pressure gauge. Fig. 118 1. Pull the drain valve (3) via the ring to the side until no water will run out of the air reservoir (1) any more.
Maintenance, repair and care work 4. Visual inspection of the brake cylinders 1. Check the dust collars or the bellows (Fig. 118/5) for damage. 2. Replace defective parts. 5. Joints on brake valves, brake cylinders and brake linkages Ensure the smooth running of all joints on brake valves, brake cylin- ders and brake linkages, if necessary grease or slightly apply oil.
Maintenance, repair and care work Tyres / wheels Check in regular intervals the firm seating of the wheel nuts. Tyre pressure (please refer to chapter 9.6.1). Important Only use tyres and rims prescribed by us. See chapter 4.2.3. Repair work on the tyres must only be carried out by skilled persons with appropriate fitting tools.
Maintenance, repair and care work Hydraulic system Only an authorised workshop is allowed to carry out repair work on the hydraulic system. The hydraulic system is under high pressure. Danger When searching for leaks, appropriate aids should be used. Before starting and work on the hydraulic system, relief the system from pressure.
Maintenance, repair and care work Prior to any putting to operation 1. Check the hydraulic hose circuits for obvious defects. 2. Remedy any rubbing points on hydraulic hoses and tubes. 3. Exchange worn or defective hydraulic hoses immediately. Inspection criterion of hydraulic hoses Please adhere to the following inspection criterion.
