Maneuvering of the boom - HV version
The switches on the hydraulic control box control the following
functions:
1 . Power ON/OFF
2. Boom folding (left side)
3. Boom lift raise/lower
4 . Boom folding (right side)
To unfold the boom, do the following:
1 . Engage the tractor’s double acting remote outlet lever and lock it in the engaged position.
2. Push switch (3) upwards to lift the boom clear of the transport brackets.
3. Push switch (2) to the left and (4) to the right to unfold both wings simultaneously.
4 . If only one side of the boom is to be used for spraying, first unfold the boom completely. Then push switch (2) to the
right or switch (3) to the left to fold the desired side back in.
5 . When the boom is completely unfolded, it can be raised or lowered to the desired spray height by pushing switch (3)
upwards or downwards.
To fold the boom, do the following:
6. Before attempting to fold the boom back into transport position, it must be raised all the way to the top by pushing
switch (3) upwards. This will enable the rear cylinder transport locks.
7. Push switch (2) to the right and (4) to the left to fold the boom. The boom can now be lowered into the transport
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! Ensure that the rear cylinder transport lock is properly engaged before transport.
±
WARNING! The folding function (switches 2 & 4) must only be operated when the sprayer is stationary! Failure to do
so will damage the boom.
˜
ATTENTION! Only unfold and fold the boom on level ground.
˜
ATTENTION! The SPB-HV boom cannot be operated with tractor’s hydraulic levers.
˜
ATTENTION! It is not advisable to go directly from transport position to spray position with one side only. Both wings
must first be completely unfolded and then one side folded back in.
