DANGER! Before unfolding the boom, it is important to connect the sprayer to the tractor to prevent overbalanc-
ing of the sprayer.
DANGER! When folding or unfolding the boom, make sure that no persons or objects are in the operating area of
the boom.
DANGER! Always follow the guidelines listed below when driving in areas with overhead power lines:
WARNING! Ensure that the rear cylinder transport lock is properly engaged before transport.
ATTENTION! Only unfold and fold the boom on level ground.
The boom must not be folded/unfolded while driving! Never use the folding/unfolding functions before sprayer has
been stopped! Failure to do so will cause damage to the boom.
Never use the folding/unfolding functions in areas with overhead
power lines.
Unintended boom movements can cause contact with overhead
power lines.
The SPB booms with hydraulic HY-version are operated as follows:
1. Activate the single acting hydraulic outlet to raise the boom and release it from the transport brackets.
2. Activate the double acting hydraulic outlet to unfold the boom. Both wings will now unfold simultaneously.
3. 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.
5. The boom is folded by activating the double acting outlet in the opposite direction that was used to unfold the boom.
The boom can now be lowered into the transport brackets.
6. 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 inches and then lower it again.
ATTENTION! A label (ref. no. 10533003) is located on the
sprayer’s drawbar. This label must be visible to the operator
when hooking up the sprayer.
