When the throttle pedal is released and the RSC
switch is ON, dynamic retarding will activate at, or
above, the RSC dialed speed and will adjust truck
speed to maintain, the dialed speed.
With the RSC switch ON and the dial adjusted, the
truck will operate as follows:
As truck speed increases to the "set" speed and
throttle pedal released, dynamic retarding will apply.
As truck speed tries to increase, the amount of
retarding effort will automatically adjust to keep the
selected speed. When truck speed decreases, the
retarding effort is reduced to maintain the selected
speed. If truck speed continues to decrease to
approximately 3 mph (4.8 kph) below "set" speed,
Dynamic Retarding will turn off automatically. If truck
speed must be reduced further, the operator can turn
the Adjust Dial to a new setting or depress the foot
operated retard pedal.
If the operator depresses the foot operated retard
pedal and the retard effort called for is greater than
that from the automatic system, the foot pedal retard
will override RSC.
RSC Control Adjustment
While operating truck at desired maximum speed:
1. Rotate RSC dial (12) clockwise to fastest speed.
2. Pull RSC switch (11) out to engage system.
3. Reduce throttle, allowing truck to coast.
4. Rotate RSC dial counterclockwise until dynamic
retarding is activated.
Dynamic retarding will now be activated automati-
cally whenever the "set" speed adjusted in the above
steps is reached, provided the RSC switch is ON and
the throttle pedal is released.

retarding will still be available.
If this light is on, notify maintenance personnel so
they can diagnose and repair the problem the next
time the truck is in the shop for repairs or at the next
PM (Preventative Maintenance) interval.
PAYLOAD METER (NOT SHOWN)
The Payload Meter and Download Connector
(located on the back wall behind the passenger seat)
is used to provide management with operational data
such as tonnage hauled and cycle times. Refer
