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 (HAY model)

Connection requirements are:
• A single outlet to raise or lower the boom.
• A double outlet to fold or unfold the boom.
• A double outlet for Hydraulic Slanting Control (optional equipment).
ATTENTION! The hydraulic hoses are marked with arrows to indicate direction of oil flow.
• Oil flow between 25 and 130 l/min and a min. pressure of 160 bar.
• Maximum permissible oil pressure is 210 bar.
• Return flow restriction of the connected tractor must be maximum 15 bar.
• For Load Sensing systems an oil flow of approximately 3 l/min at 25 bar supplied by the sprayer hydraulics.

Requirements - tractor (HAZ model)

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.
ATTENTION! The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
• Oil flow between 25 and 90 l/min and a min. pressure of 170 bar.
• Maximum permissible oil pressure is 210 bar.
• Return flow restriction of the connected tractor must be maximum 15 bar.
• For Load Sensing systems an oil flow of approximately 3 l/min at 25 bar supplied by the sprayer hydraulics.
