Hydraulic automatic release system
Before each season it has to be controlled, that the gas pressure in the accumulator (Pos.1) is 90
bars.
This requires special tools and can only be performed by an authorized dealer.
Before the start-up of the machine the hydraulic pressure in the closed hydraulic stone protection
system must be controlled on the machine’s pressure gauge (Pos. 2). The hydraulic reset pressure
should be
minimum 120 bar and must not exceed 160 bar.
IMPORTANT – the hydraulic pressure is to be controlled continuously and must never be under
100 bar.
If there is a need to adjust the working pressure, follow the below instructions:
Mount the quick coupling of the hydraulic hose (Pos. 3) in the tractor’s oil outlet.
Turn on the ball valve (Pos. 4), and the working pressure can now be adjusted up or down with the
tractor’s oil outlet.
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 are near to the machine as the tine is returning to the
working position with high speed and might throw with soil and stones.
