Instruments and Controls 101
Exhaust/Engine Brake
When operating your tractor bob-tail
without a trailer or on slippery roads,
the engine brake switch must be in the
“OFF” position. Failure to follow these
instructions can result in loss of vehicle
control and serious personal injury or
death may occur.
WARNING
A vehicle speed retardation device (such
as “Jake Brake,” “C-Brake,” “Exhaust
Brake,” etc.) is not intended to replace
the service brake system on your vehicle
nor intended to bring your vehicle to a
stop. A vehicle speed retardation device
is only intended to retard the speed of
your vehicle under certain conditions.
NOTE! It is normal for there to be a slight
delay in the application of a vehicle speed
retardation device. When using a device of
this type, be sure to think ahead and ana-
lyze conditions in order to use the device
properly.
Failure to observe these precautions can
result in loss of vehicle control and seri-
ous personal injury or death can occur.
