Hydraulic systems

General info

Ensure that the quick couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the vehicle's hydraulic oil level and top off, 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 (TERRA FORCE model)

The hydraulic system requires:
• One double-acting outlet for the electro-hydraulic operation of the boom functions. The hydraulic hoses are marked
with arrows and colored tie straps to indicate 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 4 - 10 gal/min. (15 - 38 l/min) and a min. pressure of 2610 psi (180 bar).
• Maximum permissible oil pressure is 3050 psi (210 bar).
• Return flow of the connected tractor must be maximum 215 psi (15 bar).
• For Load Sensing systems an oil flow of approximately 0.8 gal/min (3 l/min) at 360 psi (25 bar) supplied by the sprayer
hydraulics.
