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

÷
Note: This is a basic adjustment of the boom. This is only to be carried out if an adjustment of the transport brackets
is insufficient.
Procedure is:
1. Loosen the lock nuts (A) and (C).
2. Adjust the nuts at (B) and (D) until the boom sections align.
ATTENTION! The upper edges of the boom sections must align so
the hydraulic lock will engage when folded.
÷
Note: It is important that the adjustments are done
simultaneously and equally on nuts (B) and (D).
3. Tighten the lock nuts (A) and (C) again.
4. Perform the "Horizontal alignment of boom between inner,
intermediate and short outer sections" on page 6.7.
ATTENTION! Illustration shows left boom wing.
5. Fold the boom to see if it hits and rests correctly in the transport brackets.
6. If necessary to readjust, unfold the boom and loosen the nuts (A) and (C) again.
7. Adjust the nuts at (B) and (D) simultaneously and equally until the boom rests correctly in the lock bracket.
ATTENTION! The upper bolt adjusts only half of the travel, while the lower bolt adjusts the other half.
8. Tighten the lock nuts (A) and (C) to 220-370 Ft/lb (300-500 Nm).
When folded, check if the boom rests correctly at the transport pads
between inner and intermediate section (E) and between intermediate
and outer section (F).
If adjustment is necessary:
1. Loosen the four bolts (G) holding the bracket.
2. Reposition the bracket.
