a. Mount the quick coupling of the hydraulic hose (Pos. 3) in the tractor’s oil outlet.
b. Turn on the ball valve (Pos. 4) and the working pressure can now be adjusted up or
down with the tractor’s oil outlet.
c. When the desired pressure is achieved, turn off the ball valve again (Pos. 4) and the
tractor’s hydraulic system is relieved before the quick coupling (Pos. 3) is
dismounted and placed in the parking device of the machine.
During the operation of the machine the tine is swinging automatically to the rear if it meets an
obstacle. In normal circumstances the tine will automatically return to the working position again
after having passed the obstacle. At extreme obstacles and/or soil conditions it might be necessary
to stop and eventually lift the machine from the soil.
It is important that no persons is near to the machine as the tine is returning to the
