Hydraulic part (Up to no.A09001559) The front hydraulic lifting system becomes operational when the front lifting isolation valve is open. The hydraulic jacks are supplied in double effect by the "A59-2"

electrohydraulic distributor. The accumulator dampens the oscillations due to the tool traansported.

Important: Do not use the "8033", "8035" rear couplings when front lifting is used.

Measurement and check points Front lifting inspection If a malfunction appears on the front lifting, check the following in sequence:

– Close the isolating valve.

• Look for any oil leaks:

– Wait for 15 minutes.

– Inspect the hydraulic circuit from the electrodistributor to the jacks at the front of the tractor.

– In case of leak, replace the jack's gaskets.

– Mark the position on the jack rod.

• Look for any oil leaks inside the jacks:

• Perform the hydraulic checks on electrohydraulic distributors.

– Load the front lifting.

– Refer to the section on electrohydraulic distributors.

– Lift the load.

Hydraulic part (From No.A09001560) The front hydraulic lifting system becomes operational when the front lifting isolation valve is open. The hydraulic jacks are supplied in double effect by the "A59-1" or "A596" electrohydraulic valve or the "6057" mechanical valve.

The accumulator dampens the oscillations due to the tool traansported.

Important: Do not use the "8033", "8035" rear couplings when front lifting is used.

Measurement and check points Front lifting inspection If a malfunction appears on the front lifting, check the following in sequence:

– Mark the position on the jack rod.

• Look for any oil leaks:

– In case of leak, replace the jack's gaskets.

– Inspect the hydraulic circuit from the valve to the jacks located at the front of the tractor.

• Perform the hydraulic checks for electrohydraulic or mechanical valves.

• Look for any oil leaks inside the jacks:

• Refer to sections:

– Load the front lifting.

– Electrohydraulic spool valves.

– Lift the load.

– mechanical manifolds.

– Wait for 15 minutes.

– Close the isolating valve.

Online control of the "R76-1" front lifting The inline control of the "R76-1" front lifting is located on the "A100" multifunction armrest. The inline control of the "R76-1" front lifting allows actuating the "A59-2" electrodistributor.

The front lifting online control provides a proportional supply to its displacement. This control has a floating position: – Position "A": Neutral.

– Position "B", "C": Supply proportional to the displacement of the control.

D E

– Position "D": Floating position.

– Activation of spool valve for the external controls.

Note: When the inline control of the "R76-1" front lifting is activated at less than 70 % of its stroke, continuous operation is inoperative, even when set via the "Cebis".

External controls for "U59-1", "U59-2" front lifting Pressing one of the "U59" external controls of the front lifting allows achieving a flow rate equivalent to 20% the maximum flow available on the "A59-2" electrodistributor.

The distributor shifts automatically to neutral after pressing for more than 20 seconds.

Electronic components (Up to no.A09001559) Safety solenoid valve "Y330" The hydraulic circuit is fitted with a safety solenoid valve designed to set up or interrupt the control pressure required for using the distributors. When powering off the "Y330" safety valve, the (HYD) module cuts the piloting pressure supply of the auxiliary distributors. The safety solenoid valve is fitted with a 3 channel pressure reducer (2) which generates the "X" piloting pressure. The pressure must be between 21 and 24 bar.

When the solenoid is not supplied, the "X" and "Tx" lines are connected to "T". When the solenoid is supplied, the "X" piloting line is connected to "P".

In this case, an error message is displayed on the "Cebis" terminal, a lock appears on the distributor concerned, and the auxiliary hydraulic activation indicator blinks.

When the internal and external controls are actuated simulatneously, the external controls have priority, to protect the operator located in front of the machine.

The electrohydraulic spool valves are fitted with backup controls (A) that enable an implement to be moved following an electrical supply failure. Operate control (A) of the spool valve concerned.
