Spray Boom Alignment

The spray boom must be aligned both horizontally and vertically.

The centre frame, first boom segment and second boom segment must be aligned.

The first boom segments (left and right) must be aligned with the centre frame by adjusting the boom stops (A) between the centre frame and the first boom segments.

The second boom segments (left and right) must be aligned with the first boom segments by adjusting the boom stops (B). The spindle (C) in the folding mechanism between the first and second boom segments must be tightened to prevent play between the boom segments.

For sprayers with triple-folding booms, the same adjustment has to be made for the third boom segment. The third boom segments (left and right) must be aligned with the second boom segments by adjusting the boom stops. The spindle in the folding mechanism between the second and third boom segments must be tightened to prevent play between the boom segments.

The boom breakaway system has to be aligned and tightened in both horizontal and vertical directions. The boom stops between the outer obstacle protection segment and the first part of the second boom segment need to be tightened, both in forward and rearward directions (D). The vertical alignment of the obstacle protection boom segment must be carried out with the adjustable rod end (E). If there is too much movement at the boom breakaway protection, tighten the two bolts at position (D).
