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 CANNON spout (optional).
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.
Ensure that snap couplers are clean before connection!
After having operated the hydraulics and the system has been filled with oil, check tractor’s hydraulic oil level and top up
if necessary.
