    Operating instructions Filling the main tank Water is filled into the tank by removing the tank lid located right on top of the sprayer tank. It is recommended to use as clean water as possible for spraying purposes. Always fill water through the strainer basket to prevent foreign particles from entering the tank.

    Boom height Correct boom height is very important in order to achieve the most optimal spray pattern. (See Spray Technique book). Small adjustments of the boom height can usually be made with the 3- point suspension from the tractor - raising or lowering the sprayer. In crops where greater adjustments are needed the boom height can be changed manually by removing the 4 bolts holding the boom to the frame.
