TECHNICAL SPECIFICATIONS
4.2
CHECKING THE SAFETY VALVE
• With the engine running at maximum speed and the
forward speed engaged, adjust the pressure cut-off
valve
F
to 430 bar.
The two pressure control valves
H
must not be
calibrated since they are of cartridge type and already
set to 450 bar by Rexroth.
4.3
CALIBRATION OF THE MECHANICAL ZERO
The calibration of the mechanical zero
I
is required if the
machine is set to neutral position with the forward-
reverse speed lever.
• Set the forward-neutral-reverse selector to neutral
position.
• With the engine running at idle speed, adjust the
mechanical zero screw
Y
by rotating it until the high-
pressure manometer reads the same value measured
by the boost pressure manometer.
5.
SETTING THE BRAKING SYSTEM
PRESSURE (annexes 4)
• Connect a 0-250 bar manometer to position
T
(annexes 4).
• Depress the foot brake some times until the
manometer starts increasing. When it stops, the value
shown is the calibration value of valve
R
which must
be 140 bar. If the displayed value is inferior, loosen
valve
R
; if the value is greater, tighten the valve.
Note:
To check the pressure, it is necessary to
depress the foot brake some times until the
manometer restarts increasing; when it
stops in stable position, it shows the
calibration value.
Pay special attention while disconnecting
the hose from the accumulator. Oil can
splash all around. First of all, release any
residual pressure from the accumulators.
6.
SETTING THE POWER STEERING
• Connect a 0-250 bar manometer to position
Z
(annexes 5).
• Select the front axle steering mode.
• Move the steering cylinder to stroke end and make
sure the value of the power steering
A
is 140 bar. If
the value is less, tighten valve
X
; if the value is greater,
loosen the valve.
Note:
To gain access to valve
X
, remove the
protection cap (annexes 5).
