Manoeuvring of the boom - Y-versions
The SPB/SPC boom with hydraulic Y-version are operated as follows:

Activate the double acting hydraulic outlet to unfold the boom. Both wings will now unfold simultaneously.

When the boom is completely unfolded, it can be raised or lowered to the desired spray height by activating the single
acting hydraulic outlet.
4.
Before attempting to fold the boom back into transport position, it must be raised all the way to the top by activating
the single acting outlet. This will enable the rear cylinder transport lock.

The boom can now be lowered into the transport brackets.

The rear cylinder transport lock will automatically engage when lowering the boom after it has been raised all the way
to the top. To disengage the rear transport lock, simply raise the boom back up a few centimetres and then lower it
again.
