CALIBRATING THE "DA" CURVE
Do this operation by strictly following the instructions
provided as the proper functioning of pump and
transmission depends on this calibration.
• Turn the speed selector to the forward speed
position.
• Let the engine run at maximum speed and check
the high pressure value. If this value is below 430
bar, increase the pressure 425-430 bar acting on the
pressure cut-off valve
F
.
• Gradually increase the engine speed while checking
the high pressure manometer. When the pressure
gauge shows 400 bar, hold the gas pedal down and
attempt to keep this pressure value.
• If the 400bar pressure is not reached with the engine
running at 2000 revs, adjust the spark advance valve
G
(encl. 3).
The spark advance screw must never be rotated
beyond the vertical axis of the pump (observe the
reference mark on the screw).

CHECKING THE SAFETY VALVE
• With the engine running at maximum speed and the
forward speed engaged, set the pressure cut-off valve
F
at 430 bar.
The two pressure control valves
H
(encl. 3) are the
cartridge type and already set at 450 bar by Rexroth;
therefore they do not require any calibration.
6.
CALIBRATING THE MECHANICAL ZERO
The calibration of the mechanical zero
I
is required if the
machine moves when the forward/reverse speed lever
is in the neutral position.
• Turn the speed selector to neutral.
• With the engine running at idle, adjust the mechanical
zero screw
Y
by rotating it until the high-pressure
manometer reads the same value measured by the
boost pressure manometer.
