7.
Put the non-stop hydraulic circuit under pressure again/ see chapter «9.6.5.4 Th
e
performance of the ope
rations for changing of the pressure of the hydraulic non-stop security
disengagement».
10.3. HOW TO CONTROL THE SUITABLE WORK AND FITTING OF THE
HYDRULIC SECURITY ON THE ADDITIONAL PLOUGH BOTTOM
1. Fasten the plough into the transporting position and the plough bottom into the
vertical position.
2.
Eliminate the pressure in the hydraulic circuit as
it follows:
1. Open the pipe valve at the end of the
accum
ulator.
2. The circuit pressure which is in the connection
with the accumulator eliminate by putting the
distribution lever into self-adjusting position and follow
the instructions about tractor usage.
Attention, by elim
inating the pressure in
the security cylinders, the plough
bottoms cannot be kept up and there is
the risk that they may fall down. The
plough must be fastened.
3.
The manometer of the a
ccumulator must show zero.
4.
Every plough bottom mu
st go down one by one.
5.
If the hydraulic connection has been performed properly, th
e supplementary plough
bottoms sho
uld go down as well. If it does not happen we should check the fastening as it
described above.
6.
For accumulator blowing up and the circuit placing under the pressure the tracto
r
distribution
levers should be put into the operation till the manometer indicates in the green
line the required pressure.
