9.6.7.4. The operation for modification of the disengaging torque of the hydraulic Non-
Stop security.
1. Put the pull device on the ground before beginning the securities base setting.
2. Turn the plough on the right side vertically without putting the plough bottom on the ground.
3. Leave about 15 cm (6’’) between the end of the plough and the ground.
4. In the cabin put into the neutral position controling lever of the lifting device.
5. With the help of flat screw-key 2 turning open the doing cock (37).
6. As the security hydraulic circuits are in the opened position, it will be easier to add or take the
oil if the directing lever of the rear beam lifting devices is pulled back in the driver cabin.
7. After the movement of the manometer indicator (38) close the cock back (37) when the
required pressure was reached.
8. Perform test ploughing to see if the disengagement is suitable.
If the parts hammer and all the time disengage then the pressure of the security circuit should be
increased.
If the maximum set in the green line of the manometer is not enough, connect the brand dealer. He
can recommend more optional solutions to use the plough in the given conditions.
¾ The increasing of the security cylinder Ø on every element (100, 110 or 125 mm);
¾ The equipment of 150 bar pressure accumulator (nitrogen pressure).
If the plough bottom too often catch stones or there are too many stones then the industrial pressure
of the securities should be decreased.
If the pressure is too high it may obstacle the disengagement of the plough bottom during the impact.
It is dangerous because of the breaking (wearing pieces, bolts, screws, holder) the life of the plough
will be reduced because of the beam unnecessary force action.
If you have problems connect with the GRÉGOIRE-BESSON dealer who can recommend you
suitable solutions.
IMPORTANT:
If the pressure is too low then two upper supporting ball pins turns out of the case
and plough bottoms slowly go down to the ground. It is enough if the pressure will be increased
again to put the elements into the normal position.
ATTENTION:
Too low pressure can result the plough bottoms putting
down. It is dangerous as we may be injured or suffer such crush injury
which may lead to amputation or even death.
