Horizontal alignment of boom between inner, intermediate and short outer sections

Boom must be unfolded and the hydraulic lock locked.
Procedure is:
1. Loosen lock nut (A).
2. Adjust the lock bolt (B) until the boom sections align.
÷
NOTE! The lock bolt (B) is exccentric. Therefore it is important to
check that it centres on the hole in the lock mechanism while
adjusting.
3. Tighten the lock nut (A) again.

Fold lock adjustment

The "Vertical alignment of boom between inner, intermediate and short
outer sections" on page 23 must be done prior to this adjustment.
The fold lock adjustment is divided into two parts: Vertical and
horizontal adjustment:
Horizontal adjustment
1. Loosen the five bolts (A) on the fold lock bracket.
2. Repostion the fold lock until the hook is aligning to the centre of
the fold lock hole.
3. Tighten the five bolts (A) on the fold lock bracket.
Vertical adjustment
1. Loosen the bolt (B).
2. Turn the hook upside down if needed for better fit.
3. Tighten the hook bolt (B) again.

Breakaway section adjustment

The progressive breakaway function is adjusted by altering the spring
attachment point on the progressive mechanism.
The turning "half circle" part should be in a rest position as in the picture.
If out of adjustment, the "half circle" part is turned more or less as in the
picture and needs adjustment:
1. Loosen the nut (D) on the fork bolt to slacken the spring.
2. Remove the bolt (A) on the turning progressive mechanism that
holds the breakaway wire.
3. Reposition the bolt into hole (B) or (C) to adjust the "half circle" rest
position.
4. Tighten the nut (D) on the fork bolt until a suitable spring load is
achieved.
μ
ATTENTION! Observe the amount of spring load required when
driving with the sprayer. If the breakaway sections release too
much, the spring load must be increased.
