Alignment of Center Section and Inner Wing
For boom widths of 80’ - 100’.
The boom tip must point slightly forward. If necessary, adjust the inner
wing as follows when unfolded:
1. De-pressurize the hydraulic folding cylinders.
2. Loosen jam nut (A).
3. Adjust stop screw (B) until the correct setting is reached.
4. Tighten jam nut again.
Adjustment of Boom Tilt
The horizontal adjustment of the boom wings is done by the retracted
tilt cylinder. The boom must be straight and horizontal. If necessary,
adjust the wing as follows:
1. Support the boom wing with jack stands or similar to relieve the
load from the hydraulic cylinder.
2. Loosen the jam nut (A), which is positioned by the hinge ring on
the cylinder’s piston rod.
3. Adjust the cylinder ram inwards or outwards (using a wrench on
the two flattened sides on the end of the ram) to get the desired
level for the boom wing.
