Mounting Kit
The delivered parts are to be mounted on your HARDI sprayer.
They represent the boom wings to be connected to the boom centre.
Where on the Sprayer
On the left and right sides of the boom centre.
Tools and Materials Needed
Crane or forklift truck Lifting strap, 500 kg Sizes: 19 - 24 - 30 - 46 mm
Multi-purpose grease,
e.g. Shell Gadus

Instructions

Preparations
The sprayer should be hitched to the tractor to prevent it from moving
or rolling during the mounting work.
Activate the handbrake for the tractor.
Connect the hydraulic hoses for boom folding functions to the tractor
during the mounting work. Release the oil pressure to start with.
Keep children and bystanders at a distance.
Lifting The Boom Wing Into Position
The following instructions and pictures show the right side boom wing to be mounted.
Lift up the boom wing from the delivery position using a suitable lifting
strap (A) connected to a crane or forklift truck.
Pay attention to the balance when lifting.
The boom wing weighs approximately 150 kg.

Instructions
5
Move the boom wing near to the boom centre on the sprayer.
Move the boom wing carefully to avoid damaging other parts on the
sprayer during the mounting work.
Open the boom wing by means of a wood piece - this makes room for
the mounting work.

Mounting Instructions
Bearing Pins
On the boom centre, remove the black bearing pins and lock nuts at the
mounting points at the top and bottom, 4 sets in all.
Check that the bearing pins are greased, or apply extra grease now.

Instructions
7
Pivot Joints
Align the mounting holes at the bottom of the boom centre and boom
wing.
Insert the black bearing pin - use a rubber mallet if needed.
Knock the bearing pin fully through.
Mount the lock nut on the opposite side.
At the top, mount this red bracket inside the red square pipe.

Instructions
8
Fasten with bolt and nut in the bottom hole.
Note that the boom wing has been raised beyond this mounting point,
allowing the red bracket to be mounted as shown.
Prepare the mounting hole for the black steel bar connected to the
boom centre.
Raise or lower the boom wing to align the mounting holes.

Instructions
9
These parts are used to mount the black rod.
Tighten the locknut at the end of the steel bar.
Four thread turns must be visible when finished - this is close to the final
setting for the boom wing.

Instructions
10
Connect the other end of the steel bar as shown.
Lift the boom wing to a horizontal position, and place a support under
the boom wing.
Remove the lifting strap, and move over to mount the opposite boom
wing.
This will create a good balance in the boom for the coming mounting
work.
Opposite Boom Wing
Repeat the steps for mounting the opposite boom wing in the pivot joints.
When completed, lift the boom wing to a horizontal position, and place a support under the boom wing.
Now return to the first boom wing to complete the work here.
Hydraulic Hoses
Remove the dust caps from the hydraulic cylinder on the boom wing
and on the hydraulic block in the boom centre.
Check that the O-rings are mounted in the oil ports in the cylinders after
removing the dust caps. If not, you will have leaks during operation!

Instructions
11
Connect the hoses to the hydraulic cylinder.
Tightening torque: 28 Nm.
1. Hose length = 2.0 meters
2. Hose length = 2.3 meters
Hoses for other boom wing.
Note the path from boom centre to hydraulic cylinder.

Instructions
12
When connecting the hoses to the hydraulic block in the boom centre,
note the oil flow direction:
Left side of the block is for
•pressure lines
•hose length = 2.0 meters
Right side of the block is for
•return lines.
•hose length = 2.3 meters
Bundle the hoses together and attach them to with cable ties where
cable ties. Note that the hoses will move a little when pressurized.
Refrain from attaching hoses (and cables) to the moving steel parts in
the centre of this picture behind the hoses.
Tightening the Boom Wing
Disassemble the four black rigging screws.
Adjust the nuts to a distance of 20 mm from the end of the threaded
pins. This will facilitate adjustments later.
Reassemble the rigging screws

Instructions
13
Adjust the chain on the chain wheel.
There is to be five free chain rolls after the red bracket with the fifth chain
roll aligned with the bolt line on the chain wheel.
Unfold the boom wing fully by hand.

Instructions
14
Check that the rigging screw (B) on the backside of the boom wing is
mounted.
Pull the rigging screw on the front side to the mounting point above the
hydraulic cylinder on the boom centre.
The pulling may seem hard due to the spring force - you might need an
extra hand, or a lifting crane (as shown) to assist getting the rigging
screw into position for mounting.

Instructions
15
Mount the rigging screw with the black pin bolt and black ring (see the
arrow).
Secure with a cotter pin at the top.
Turn the rigging screw, until the arch on the steel wire is straightened
out along the spring

Instructions
16
Turning can also be carried out with a screw driver or similar inserted in
the hole in the body of the rigging screw.
When the steel wire is straight, turn the rigging screw an extra two turns.
The rigging screw on the opposite of the boom wing is not adjusted yet.
Apply hydraulic pressure and fully extract the hydraulic cylinder pistons
for the boom wings = full unfolding of the boom wings.

Instructions
17
Vertical Adjustment of Boom Wings
Loosen the four bolts in the boom centre (no dismounting!) until they
can be turned by hand.
Wrench size: 24 mm.
This will facilitate the boom movements when driving in the field.
Position of the four bolts in the vertical boom structures.
Place a spirit level on the middle of the boom centre. Check the
horizontal position.

Instructions
18
Place a spirit level on the middle of a boom wing.
The far end of the boom wing should be raised a little relative to the
horizontal position.
The bubble in the spirit level should just be touching black line as shown
here, then the adjustment is all right.
To adjust the boom wing up or down, turn the nuts holding the black
steel bar at the top.
Pull the black steel bar at the top towards the boom centre to raise the
boom wing or the opposite way to lower it.

Instructions
19
Tighten both nuts when adjustment is finished.
Repeat this adjustment for the other boom wing.
Horizontal Adjustment of Boom Wings
To counteract for the unfolded boom moving backwards when driving
in the field, both boom wing tips are adjusted to be a little ahead at
standstill (B).
The adjustment is to be 1 cm forward per boom meter.
Check again that the boom wings are fully unfolded be means of the
hydraulic folding cylinders.
The boom sections must be aligned with each other when unfolded.
Adjust the stop bolt below the chain wheel if adjustment of alignment
is needed.
Wrench size: 19 mm.

Instructions
20
The boom sections are aligned correctly, when the black liquid pipes are
in a straight line.
Measure horizontally from a fixed point on the first nozzle holder and
out in front of the boom to another fixed point.
In this case a laser light is positioned on the boom centre and marking
the current position on the measuring tape.
Now measure the same way near the boom tip to see the difference.
