Rear axle´s command cylinder
Front axle´s
command cylinder
Installation of the cylinder:
To do this operation, we can´t have any pressure in the circuit. If your machine has only one
cylinder, the automatic lock system enables its easy implementation. Simply attach the
cylinder to the tractor and slowly steer for blocking. However, if your vehicle has the two
cylinders on the jib, put cylinders up manually.
The adjustment should be made with the tractor and trailer hitched
aligned, straight wheels, cylinder attached. It is recommended to drive
straight ahead for about 10 meters. Make sure the handbrake of the
tractor is pulled.
Close the selector valve of the circuit
Open the isolating valves of the different circuits.
Using the manual pump, increase the pressure of the circuits
Between 20 and 35 bars maximum for mounting of a simple cylinder with a diameter of
40/80(the manual pump's valve must be closed)
Between 20 et 35 bars maximum for the mounting of a double cylinder
When the pressure stabilizes (it is tolerated a deviation of 5 bars) close the valves of the
circuits.
To re-use the hydraulic jack, simply re-open the selector valve. (make sure the auto-pilot
valves are closed)
To decrease the pressure in the circuit, you must close the selector valve of the circuit,
open the valves of different circuits and open the valve on the hand pump. The oil then
returns to the pump.
