Boom tilt function - ‘DH’ control
WARNING! Ensure that the rear cylinder transport lock is properly engaged before transport.
ATTENTION! Only unfold and fold the boom on level ground.
On tractors with ‘closed center’ hydraulic systems, the SPB booms
with hydraulic HZ-version are operated as follows:
1. Activate the single acting hydraulic outlet to raise the boom and
release it from the transport brackets.
2. Engage the tractor’s double acting remote outlet lever and lock it
in the engaged position.
3. Activate switches A and B upwards and hold to unfold both wings
simultaneously.
4. “One side folding” will be achieved by following step 3 except that
only one of the switches is activated. See section “Folding one side
only”.
5. When the boom is completely unfolded, it can be raised or low-
ered to the desired spray height by activating the single acting
hydraulic outlet.
6. Before attempting to fold the boom back into transport position,
it must be raised all the way to the top by activating the single act-
ing outlet. This will enable the rear cylinder transport locks.
7. The boom is folded by holding switches A and B downwards (with
tractor’s double acting remote outlet lever still locked in the
engaged position). The boom can now be lowered into the trans-
port brackets.
8. The rear cylinder transport locks 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.
WARNING! Unexpected boom movements may occur if wings are tilted when folding.
WARNING! Never use tilt function when boom is folded into transport position.
WARNING! Never attempt to fold boom to transport position when wings are tilted. Always let wings down to hor-
izontal position prior to folding.
WARNING! Never attempt to work on or around wing section when tilted up.
