2 HYDRAULIC CONTROL AND ADJUSTMENT
Remove the protective cap of the pressure test (Ref. 2) tted
on the side of the directional control valve (Ref. 1).
In vehicles 7140 - 990 - 10160 - 10180 - 10210 - 10225 access
the directional control valve from the vehicle area under the
boom.
For type 10120 vehicles, access the pressure test connector
(Ref. 2) through hole (Ref. 3) on the LH side of the truck frame.
Connect a pressure gauge to the pressure test connector (Ref. 2)
by means of the exible tube provided for the purpose (Ref. 4).
CHECKING PRESSURE VALUES
To check the pressures, use a pressure gauge with minimum scale 400 bar.
The oil temperature must be about 60, the I.C. engine must be at the maximum rpm for all the checks.
If the pressure is 200 bar, rst of all, check the anti-block valve alongside the pump (LH side).Check the consistency of the values measured with the data shown on the hydraulic layouts:

Check the pressure value of the relief valve bringing the boom all the way down; if the pressure is not
set at the correct value (350 bar), adjust the screw (Ref. 5) on the valve.
BOOM MOVEMENTS
Check the pressure values of the various movements of the boom, bringing the cylinders concerned to
the limit stop and act on the valves concerned to adjust them (see Table).

4 HYDRAULIC CONTROL AND ADJUSTMENT
COMPENSATION EXCLUSION CIRCUIT VALVE
The correct values of the compensation cylinder pressures
must be:
Rod side anti-shock valve = 350 bar
Bottom plate side anti-shock valve = 200 barIn optimum value conditions, the adjuster screw (Ref. 11) on the
bottom plate side must project by about 7mm and the adjuster
screw (Ref. 12) on the rod side must project by about 6 mm.
If the values are not correct, act as follows:
Slacken screws (Ref. 11 and 12) completely
Raise the boom all the way and act on the slewing movement
Bring the boom all the way down and act on the slewing
movement; repeat these operations 3 or 4 times to remove
air, if any, from the compensation circuit
Retighten the adjuster screw (Ref. 11) until it projects byabout 7 mm.
Retighten the adjuster screw (Ref. 12) until it projects by
about 6 mm.
SLEWING CYLINDER BLOCK VALVE
In case the slewing movement start is delayed or is slowed, act
on the control air regulator valve (Ref. 13) of the slewing cylinder,
always leaving a minimum valve opening pressure of 80 bar.

LEVELLING
Check the levelling pressure by means of the pressure test
connector (Ref. 14) positioned on the pump and act on valve
(Ref. 15) to adjust the pressure.
Check the levelling until the cylinder limit stop is reached; thevalue must be 205 bar.
DIRECTION
After adjusting the relief valve pressure to the correct value
(350 bar), check the pressure of the power steering (Ref. 16), by
means of the same pressure test connector and, if necessary,
act on valve (Ref. 17) to bring the value to 190 bar.

6 HYDRAULIC CONTROL AND ADJUSTMENT
CHECKING THE HYDRAULIC PRESSURE OF THE LS CIRCUIT
Check the hydraulic oil level.
Dismantle the housing of the valves unit (Ref. 18) behind
the vehicle.
Bring the oil to the operating temperature (50) by performinghydraulic movements.
Note: Below 1200 min-1the valves unit pressure does not exceed
200 bar.
CHECKING AND SETTING THE STANDBY PRESSURE
(To make the connection also adjust the FR regulator)
Connect the 0-600 bar digital pressure gauge to the pressure
test connector (Ref. 2). Insert the rev counter.
With the engine running at minimum speed and without
making any movement, read the pressure value on the
pressure gauge.
Standby pressure: 30 bar 3.
If the pressure is not correct, turn the FR adjuster screw (Ref.
19) on the main pump. Tighten the screw to increase the
pressure, slacken it to reduce the pressure.
Note: If the pressure cannot be adjusted by means of this
operation, refer to the indications on page 2
Using the rev counter, check the minimum engine speed:
850 min-1.
Adjust, if necessary.
CHECKING THE ANTI-STALL VALVE
A - With the I.C. engine running at minimum speed, press the
manipulator button (accessories circuit).
- Progressively increase the engine rpm.
- Note down the number of rotations at which the pressurechanges from 200 to 350 bar (approx. 1200 100 min-1).
B - With the I.C. engine running at maximum speed, press the
manipulator button (accessories circuit).
- Progressively reduce the I.C. engine rpm.
- Note down the number of rotations at which the pressure
changes from 350 to 200 bar (approx. 1200 100 min-1).
Note: The anti-stall valve (Ref. 20) does not work correctly in
the following cases: The main pressure remains at 200 bar.
The main pressure remains at 350 bar (engine stop at minimum).
Pressure unstable.
