IMPORTANT ADVICES
- InorderthattheAXIALEIIsuspensionprovidesyouwithcompletesatisfaction:
- running in is needed, and this takes place in the first few hours of operation,
- it is highly recommended that you grease moving and frictional parts before each use.
- Choose correct advance speed for your field, and do not make rapid or ill-considered changes of direction:

balance point
- TheAXIALE suspension "autostablependular" type,
isbased ontheprinciple ofabalance positioned near
thegravity center of the boom.
- Balanceis maintained, and, consequently,the boom
remains parallel to the axle, as a result of the action
of 4 springs (20/21/24/27/28 m) or for 6 springs
(30/32/33m).
- These springs continuously correct position of the
boom.
- Two shock absorbers provide a final filter against
shocks.
- Angle correction, is provided by a ram acting on the
floating and stabilizing bar to which the springs are
attached.

ADJUSTMENT OF THE ARMS
ADJUSTMENT OF THE BOOM
- Your boom is equipped with a device which adjustsarm alignment in working position and adjustment for
thetransportposition.
ADJUSTMENT OF THE MAIN ARMS
IN TRANSPORT POSITION (figure 1):
Arms closed in transport position (they must be fully against the arm supports).
- Removethepin (5) (figure 1) then actuate the unfolding actuators (1) in open position (end of travel).
- Adjustment of the ball joint (4):
- unscrew the set screw (2),
- unscrew the socket (3) to gain access to the set screw (6),
- adjust the ball joint (4) so that the pin (5) can be replaced easily,
- tighten the set screw (6) and adjust the socket (3) for working position.
IN WORK POSITION (IN THE HORIZONTAL PLANE):
Open the arms fully.
- Check the alignment in the horizontal plane.
- If not horizontal, decompress the actuators, then loosen the set screw (2) so that you can tighten or
loosen the socket (3) (figure 1).
- Open the arm again to check the alignment.
- Repeat the operation until the desired setting is obtained.
- Tighten the set screw (2).
IN WORK POSITION (IN THE VERTICAL PLANE):
Open the arms fully.
• Case of booms without GV (variable geometry) (figure 2):
- Adjust the main arms (2) by turning the coupler (1) positioned on the upper part of the arm.
• Case of booms with GV (variable geometry) (figure 4):
- Thesebooms areequipped with aposition indicator(2)and anoptional automatic reset(2 positionsensors
(1) (figure 3)). The actuator (1) (figure 4) is used to incline the arm.
• Adjustment of reset sensors (figure3):
- If your reset is not correct adjusted:
- open the arms in work position (see electrical control box, pages 17, 18 and 20),
- loosen the nuts (2),
- slide the sensors (1) into the opening up to the limit of illumination of the LED located on top of the
sensor; when the LED goes out, retighten the nuts of the sensor.
WARNING:
The sensors (1) (figure 3) must have a clearance (a) between 2 and 4 mm.
WARNING:
- Spray equipped with GV (variable geometry):
The GV must be positioned on 0 before folding the boom.

LOCKING OF A BOOM WITH AN
HYDRAULIC LOCK (figure 7)
- Before making any adjustments, make sure that the central part is in horizontal position.
To adjust the lock, extend the actuator rods (1), loosen the locknuts(2), end tips(3) fully against the oscillating
framethen retighten the locknuts (2).
LOCKING OF A BOOM WITH A
MECHANICAL LOCK (figure 9)
- The adjustment of a boom with mechanical lock is done with the boom open in raised, horizontal position.
- The cable (3) must be tightened by screw/nuts (4), without hindrance.
- Ifthe cable is not taut,loosen the eyebolts/nuts (4)completely, tighten the cable using the twocable clamps(5)
only, they retighten it using the eyebolts/nuts (4).
-Note : To use the boom in HIGH POSITION, on each side, you must withdraw the joining shackle (6) from the
oscillating frame (7), and hook the joining shackle (6) on the ring (2) of the lock (1).
FLOW LIMITERS ON INTERMEDIATE ARM (figure 8)
- The flow limiters (1) fitted on the boom's rams are used to adapt the speed of the boom's lifting and folding
movementsto suit the fluidity of the oil and the flow rate of the tractor within the limits of good agricultural use.
- Procedure:
- Unscrew the hex-socket cap screw (2) situated in the flow limiter's adjusting wheel (3).
- Adapt the flow limiter's setting.
- Make sure that the adjustment is correct (speed of movement not too fast).
- Tighten the hex-socket cap screw (2).
IMPORTANT:
- The adjustment must be carried out without anyone in the boom's working radius
and without risk of untimely movement of the boom.
WARNING:
- Before folding the boom, replace the cables (3) correctly on the oscillating frame (7).
IMPORTANT :
- Before each treatment and after unfolding arms, the boom must be unlocked.
- Before folding arms and during transport operation, lock the boom to the oscillating
frame (refer to the technical manual of your device).

ADJUSTMENT OF LOWERING AND SUSPENSION
OF THE BOOM (figure 10)
- The limiter (1), located below the hydraulic units, is used to set the boom's lowering speed.
- Nitrogencylinders mounted on the raising cylinders are used for vertical damping of the boom.
(The more open the limiter, the more brutal the shocks. Do not close the limiter completely).
ADJUSTMENT OF ARM SUPPORTS (figure 11)
- The boom is mounded on the sprayer in low position.
- It can be raised using the arm supports (2).
- With the boom in closed position, adjust the arm supports 10 cm above the wood plate (3).
- Removethe bolts (1), respecttheholes used to ensureproperinclination of the supportandplace the supports
(2) in position (A) or (B).
- Replace the bolts.
- Note: When at rest or during road transport, lower the boom so that it touches the arm support wood plates
(3)alongtheir entire length.
Do not attempt to lower the boom beyond this point as damage may be result.
WARNING:
- Sprayer with axle suspension:
When folding the boom arms, leave at least 150 mm between the top of the tank and
the main arm (make modifications with arm geometry).
WARNING:
- Spray equipped with GV (variable geometry):
The GV must be positioned on 0 before folding the boom.
ADJUSTMENT OF THE ARM STOPS (figure 12)
INTERMEDIATE AND END ARM'S STOP
- Makesure that stops (1), (2) and (3) correctly touch the intermediate andendarmswhen the boom is in folded
position.
- To do this, loosen the nuts, move the stops and tighten the nuts.
BOOM HEIGHT IN TRANSPORT POSITION
- Whenlowering the boom onto itssupports, always ensure that thereisat least 100 mm betweentheboom arm
and the tank.

- Procedure:
- Unscrew the hex-socket cap screw (2) situated in the flow limiter's adjusting wheel (3).
- Adapt the flow limiter's setting.
- Make sure that the adjustment is correct (speed of movement not too fast).
- Tighten the hex-socket cap screw (2).
ADJUSTMENT OF THE ANGLE CORRECTOR
RESET OPTION (figure 14)
- Adjustment of reset sensors:
- If your reset is not correct adjusted:
- check that the mobile frame (3) is level (arms open),
- loosen the nuts (2),
- slide the sensors (1) into the opening up to the limit of illumination of the LED located on top of the
sensor; when the LED goes out, retighten the nuts of the sensor.
CENTRAL PART ADJUSTMENT (figure 15)
INSPECTION OF THE CENTRAL PART:
- Your boom is equipped with an anti-whipping device to ensure the best possible boom behaviour; regularly
check that the 2 bolts (3) are tightened.
SYNCHRONISATION OF THE MAIN ARMS:
- Thisdevice consists of a flow divider (1) and two flow limiters (2) with a built-in control valve. No adjustment is
necessary for the opening and closing speed of the main arms.
WARNING:
- The sensors (1) must have a clearance (a) between 2 and 4 mm.
