Operation 5
Machine travel with the compressed-air braking system of the
trailer
Performing machine travel too fast can cause serious accidents!
The trailer brake can overheat on longer downhill stretches with the
brake-inch pedal pressed only halfway through!
Can cause serious injury or death.
► Reduce the travel speed early enough before turning or downhill
machine travel (pump brakes). Press the brake-inch pedal 34 as far as
it will go to brake the machine.
► Take your foot off the accelerator pedal to reduce the engine speed.
► Select the “Turtle” speed range.
When the machine is braked with brake/inching pedal 34, air pressure is
applied to the compressed-air braking system of the trailer to brake it.
Applying the parking brake also applies it to the compressed-air braking
system of the trailer.
If the travel speed is reduced with the brake-inch pedal 34, a pressure of
about 2 bar (29 psi) is applied to the compressed-air braking system of the
trailer after about 20% of the pedal travel. This “advance action” slightly
brakes the trailer, and the tractor-trailer combination is held in a taut line.
The trailer brake can overheat on longer downhill stretches with the brake-
inch pedal pressed only halfway through!
► Press the brake-inch pedal as far as it will go to brake the machine.
