VEHICLE SPEED RETARDING DEVICES
When operating a tractor bobtail (without a trailer)
or on slippery roads, the engine brake switch must
be in the “OFF” position. Failure to follow this
instruction can result in loss of vehicle control and
serious personal injury or death.
The vehicle ABS will automatically turn off the vehicle
speed retarding device, IF one of the sensed rear
wheels is locking up as a result of vehicle speed
retarding device operation. The vehicle speed
retarding device will be turned back on automatically
when the wheels become unlocked. Consider
switching to a lower braking level if this occurs
frequently.
A vehicle speed retarding device is not intended to bring the vehicle to
a stop. A vehicle speed retarding device is only intended to retard the
vehicle speed under certain conditions.
It is normal for there to be a slight delay in the
application of a vehicle speed retarding device. When
using devices of this type, be sure to think ahead and
analyze conditions in order to use the device properly.
