5HORIZONTAL BOOMS FOR HERBACIOUS CULTIVATIONS
5.2HYDRAULIC HERBICIDE BOOMS
These are made in of steel painted with epoxy paint or hot galvanised. The jet booms are made of stainless steel with the jets mounted normally ever 50 cm.
All of the booms are folded onto the central body and the external arms have safety joints to prevent breakages.
In the case of a knock the boom bends to avoid the obstacle and normally re- turns to the working position automatically. In any case the operator should try to avoid knocking against objects as this could damage both the boom and the obstacle in time; all the more so if the two elements get stuck. Check that no one and nothing is in the area where the booms will open; par- ticular attention should be paid to the presence of any electric power lines. The hydraulic plant can be fed from the hydraulic pump of the tractor or be fully independent.
-The hydraulics are controlled by a hydraulic distributor with mechanical or
-All of the controls on both versions are sustained action controls and each lever or switch has a pictogram of the relevant operation it controls.
See the enclosed handbook for instructions on the use of the electrohydraulic version (Elettroil).
WARNING: with hydraulic booms, don’t stand in the range of action of the machine.
Pay attention to the integrity and efficiency of the hydraulic components and in particular to the pipes to prevent the risk of bursting.
Do a full check on the pipes and components at least once a year, we recommend replacing hydraulic pipes every
5.1.1 INDIPENDENT HYDRAULIC PLANT
In this case there is a tank, a filter and a hydraulic pump fitted with a flange behind the main pump of the sprayer.
IMPORTANT:The entire plant is designed to be used at 540 RPM. Periodically check the oil level in the tank and avoid filling it over 3/4 full as the oil might overflow.
The tank has a filler cap with a breather, when the need arises (for repairs or to replace a component) you can drain the oil by disconnecting the suction pipe of the pump and collecting the oil in a recipient.
WARNING: the oil used mustn’t be dispersed in the environment and must be collected in the relevant containers.

Consult the use and maintenance manual of the tractor.

=For manual or electric distributors (Elettroil), the distributor inlet pipe is connected to the aluminium flow separator valve next to the distributor (see photo).
The flow separator must be adjusted correctly so it send less than
To prevent the cylinders moving at a dangerous speed, adjust the relevant chokes near the cylinders. If the registration ring nuts aren’t visible then fixed chokes are fitted. The chokes are fitted on the discharge line of the movement to slow.
Any impurities in the oil could block the chokes and as a consequence block the cylinder; remove the dirt if necessary.
The maximum pressure valves of the distributors are regulated to a pressure of around 150 bar.
