Adjustment of Boom Tilt

The unfolded spray boom must be horizontal to begin with, before you start a spray job. If needed, horizontal adjustment
of the boom wings is possible when adjusting the ram eye on the hydraulic cylinder for tilt motion on both sides of the
sprayer.
÷
NOTE! This boom can tilt down to max. 4 degrees below horizontal level (only if the AutoHeight function is installed).
Steps for adjustment:
μ
ATTENTION! If the hydraulic cylinder is not to be replaced, it is not necessary to disassemble the ram eye / hydraulic
cylinder from the boom, when using a wrench for adjustment, as it is described in the following steps. Instead, the
piston rod can be rotated by turning it with a wrench placed just behind the ram eye, thus avoiding decoupling the
hydraulic cylinder from the boom.
1. Disconnect the ram eye from the boom parts.
2. Loosen the counter nut (A) and the pin bolt inside. This will unlock
the ram eye from the cylinder's piston rod.
3. With a wrench fitted on the flat surfaces on the end of the ram eye
(above A), the ram eye is now turned inwards or outwards in
relation to the cylinder. The direction depends on your need for
adjustment.
To raise the boom wing: Turn the ram eye inwards.
To lower the boom wing: Turn the ram eye outwards.
4. To be able to lock the ram eye to the piston rod after adjustment,
turn the ram eye 1 full round at a time; this will move the ram eye
2 mm sideways.
5. Reconnect the ram eye to the boom parts to check the horizontal
level of the boom wing.
If further adjustment is needed, go back to step 2.
If horizontal alignment is OK, tighten the pin bolt and the counter
nut (A).
Adjustment is now completed.
