Hydraulic systems

General info
Ensure that snap couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check tractor's hydraulic oil level and add oil 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 (SPB/SPC HY-model)
Connection requirements are:
• One single acting outlet for the lift function of the spray boom.
• One double acting outlet for the folding function.
Ensure that snap couplers are clean before connection!
The hydraulic system requires a minimum oil pressure of 2,175 p.s.i. (150 bar), max. oil pressure of 3,050 p.s.i. (210 bar) and
an oil capacity of approx. 6.6 gal (25 liters).
˜
ATTENTION! After having operated the boom and the system has been filled with oil, then check tractor's hydraulic
oil level and add oil if necessary.
±
WARNING! Due to the variation in tractor hydraulic systems and capacities, care should be exercised when initially
operating the sprayer hydraulic cylinders. It is advisable to adjust the hydraulic flow control down to the minimum
rate before operating the system. Adjust/increase the flow control after the system is bled of any air, if necessary.
Requirements - tractor (SPB/SPC HZ-model)
The hydraulic system requires a double acting hydraulic outlet. The hydraulic hoses are marked with arrows to indicate
direction of oil flow.
The hydraulic system requires an oil flow between 6.6 - 34.3 gal/min. (25 and 130 l/min) and a min. pressure of 2500 p.s.i.
(170 bar).
