  • Page 2: Intended Use

    Only use genuine LEMKEN spare-parts. Spurious parts negatively influence the function of the implement, show a shorter lifetime and increase in nearly all cases the maintenance effort. We trust that you will understand that LEMKEN is unable to guarantee poor operation and damage caused by using spurious parts!
  • Page 3 ’General Health- and Safety precautions’! • Your LEMKEN-field sprayer has been designed purely for the spraying of insecticides, fungicides, herbicides in the form of suspensions, elmusions and mixtures as well as of liquid fertilizers for the agricultural use.

  • Page 16: Valve For The Internal Cleaning

    3.2.3 Valve for the internal cleaning The internal cleaning valve (3) must be set to “Internal cleaning ON” for cleaning the inside of the main tank. The intensity of the internal cleaning can be increased if the distribution valve is set to the “chemical inductor”. (a) Internal cleaning ON.

  • Page 17: Distribution Valve

    3.2.4 Distribution valve In combination with a chemical inductor, the liquid conveyed by the pump is delivered via the distribution valve (4) either to the spray boom or to the chemical inductor. If no chemical inductor is present, the valve is usually in the “spraying” position.

  • Page 18: Induction Valve

    3.2.5 Induction valve The liquid from the chemical inductor is delivered into the main tank by activating the induction valve (5). The induction valve operates proportionally. It should therefore only be activated insofar as there is always sufficient water remaining in the chemical inductor for dissolving the medium.

  • Page 19: Valve Block Of The Chemical Inductor

    3.2.6 Valve block of the chemical inductor All filling and cleaning functions of the chemical inductor as well as the functions of the outside cleaning are performed using the individual valves of the valve block (7).

  • Page 30: Separate Internal Cleaning Of The Chemical Inductor

    Separate internal cleaning of the chemical inductor Internal cleaning of the chemical inductor (1) must be performed after the induction of spray mixtures and also after a canister rinsing. If the filling is done using a filling hose, this is done already during the filling of the main tank with clean water.
  • Page 31 − Switch on the boundary wetting with the lever (6), the agitating nozzle with the lever (9) and the canister rinsing with the lever (11). − Close the cover. − Operate the pump(s) at low speed for a short time. −...

  • Page 33: Spraying

    Spraying − Switch on the pump(s). − Thereby, it must be ensured that the power takeoff of the tractor operates smoothly at low engine speed. − The maximum permitted pump speed is 540 rpm. − Unfold the spray boom and adjust it to the specified spacing before starting spraying.

  • Page 34: System Cleaning When The Main Tank Is Empty

    System cleaning when the main tank is empty Before cleaning the system when the main tank is empty, first carry out the internal cleaning of the main tank and afterwards the internal cleaning of the chemical inductor. The internal cleaning of the chemical inductor is not necessary if it has already been done as recommended during the external filling of the main tank...
  • Page 35 − After spraying the contents of the main tank, the cleaning process described above must be repeated twice.

  • Page 36: System Cleaning When Main Tank Is Partially Filled

    System cleaning when main tank is partially filled If the filled or partially filled main tank cannot be sprayed until it is empty or transfer pumped, a system cleaning must be performed. − Switch off pump. − Close the rinsing valve (1) of the pressure filter (2).
  • Page 37 − Switch on the pump and operate at low speed until clean water discharges from the nozzles. − Switch off pump. − Put the main switch on the on-board computer in the “spray boom OFF” position. − Use the pressure adjustment to put the spraying pressure back in the middle position.

  • Page 38: Emptying The Machine

    Emptying the machine ATTENTION! Pesticides must not be left on the side of paths or introduced into the sewer system under circumstances. Collected pesticides must be taken to the specified waste disposal location (ask for the responsible place) recycled (after consultation with the respective pesticide manufacturer).

  • Page 39: Volumetric Measurement And Calibration

    Volumetric measurement and calibration 4.9.1 General The actual spraying pressure and nozzle wear are determined with the volumetric measurement. A volumetric measurement is always necessary if the output quantity of the machine deviates from the output quantity in the spraying table of the nozzles used.
  • Page 40 - Switch off the machine. - Divide the collected liquid by the number of measurements = l/min per nozzle (e.g. 4.5 l: 3 measurements = 1.5 l/min/nozzle). - If individual nozzles show deviations from each other, the nozzles must be checked on a tester and/or replaced.

  • Page 42: Cleaning

    5 CLEANING Rough cleaning The rough cleaning must be done as a matter of principle after completion of the spraying work on the field before “drying-in” of the remaining mixture can occur. See also the sections “System cleaning when the main tank is empty” and “Internal cleaning of the chemical inductor”.

  • Page 43: Outside Cleaning

    Outside cleaning The field sprayer must also be cleaned on the outside after the internal cleaning. The external cleaning is used for care of the machine and also prevents the dripping or running-off of adhering spray mixtures. The cleaning equipment hose can be connected to the connection with the GEKA coupling (1).
