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.
