Operating Characteristics
Low idle speed
Once the engine starts and the accelerator pedal is
released, a return spring pulls control lever (6) back to
the low-idle position. Linkage lever (5) is now up against
idle-speed stop screw(10).
During warm-up, low idle speed follows the idle-speed
control curve and stabilizes at Point L.
When speed increases, flyweights (22) move outward,
and shift governor sliding sleeve (20) to the right. During
operation within the idle range, sliding sleeve
movement is transmitted through reverse-transfer lever
(11) and fulcrum lever (13); moving the control rack (4)
toward Stop (shutoff). At the same time, sliding-sleeve
movement causes guide lever (9) to swivel about pivot
point A, compressing the idle leaf spring (12). This
spring's pretension (and thus the low idle speed) is
set using adjusting screw(8). At a given speed, the
fulcrum lever also comes up against the adjusting nut
for auxiliary idle spring (14).

Intermediate speed
After passing through the idle stage (a), governor
sliding sleeve (20) and spring retainer (18) for torque
control come into contact with each other. In the
uncontrolled range between idle and maximum speed,
the position of the flyweights (22) remains constant up
to high idle (maximum) speed, the only exception being
for minor adjustments necessary for torque control.
Control-rack setting and therefore delivery quantity are
selected directly through control lever (6).
That is, the driver uses the accelerator pedal to select
the delivery quantity necessary to increase speed or
climb hills (control-lever position between idle stop and
full-load stop).
If the driver depresses the accelerator pedal fully, the
control rack shifts to the full-load delivery setting.
