Hydraulic systems
General info
Ensure that the snap couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the tractor’s hydraulic oil level and top up, if
necessary.
€
DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which
can cause violent movements of the boom.
€
DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Due to high
pressure, hydraulic oil may penetrate the skin.
Requirements - tractor
The hydraulic system requires:
• One double-acting outlet for the electro-hydraulic operation of the boom functions.
• One double-acting outlet for the operation of the FlexCapacity pump (optional).
• One double-acting outlet for the operation of the hydraulic support leg (5500/7000).
ATTENTION! The hydraulic hoses are marked with arrows or colored tie straps to indicate the direction of oil flow. Red
tie strap = pressure. Green tie strap = Return to tank. The hoses must be hooked up to the correct outlet for the
hydraulics to function properly (pressure hose to pressure outlet, return hose to tank outlet).
• Oil flow between 3 -24 gal/min (10 and 90 l/min) and a min. pressure of 2500 p.s.i. (170 bar) for Force™ booms.
• Oil flow between 13 -34 gal/min (50 and 130 l/min) and a min. pressure of 2800 p.s.i. (190 bar) for Terra Force booms.
• Maximum permissible oil pressure is 3000 p.s.i. (210 bar).
• Return flow restriction of the connected tractor must be maximum 220 p.s.i. (15 bar).
• For Load Sensing systems an oil flow of approximately 0.8 gal/min (3 l/min) at 360 p.s.i. (25 bar) supplied by the sprayer
hydraulics.
