10.7.2 Side damping
Side forces, which occur during driving on the spraying equipment, are controlled by
polyurethane springs, installed between boom holder and fastening holder of the boom. It is
important that the springs are equally pre-tensioned, to ensure setting of spraying equipment, in
case of side tilting, in original position
.
Polyurethane springs are factory pre-tensioned – factory length of spring with washers is 90±3
mm. If the sprayer does not return to original position correctly, the springs must be correctly pre-
tensioned by tightening/loosening the nut, so that the equipment is perpendicular to the chassis.
When a spring loses its elastic properties (becomes stiff), it must be replaced.
10.7.3 Two-point fastening of spraying equipment and hydraulic damping
Swing frame is fitted on swing frame holder in two points, which enables movement of spraying
equipment in all directions and good central position. Two-point fastening system enable better
stability and control during operation. Fastening between use and pendulum is done with
tensioners (factory set at 420 mm)
.
Factory damping is done through a hydraulic cylinder, which enables floating fastening of
equipment. It is fastened diagonally between parallelogram fastening and swing frame.
Cylinder response is set with choke on the cylinder, which is filled with ATF oil.
WARNING: Never remove the choke bolt, to prevent oil spill. Warranty is void in
case of modifying the hydraulic damper. Repairs can be performed only by an
authorized service.
