disconnect and stop up the Inching flex in order to use
the service brake.
Forward movement, high speed engaged, engine in
maximum regime.
2-
Accelerate the engine slowly in order to raise the
pressure gradually in the H.P. circuit.
3-
Read the speed in rpm by placing an optoelectronic
sensor on the fan pulley.
4-
Measure the high pressure (1 fig. 1) using the
manometer.
5-
If the regime of the engine is too high, turn the screw
(1 fig. 2) clockwise in order to reduce the number of
rpm.
The adjustment screw acts on an eccentric,
therefore it must not be tightened or loosened
by more than a quarter-turn .
