Performing machine travel with the hydraulic trailer brake
WARNING
Performing machine travel too fast can cause serious accidents!
The trailer brake can overheat on longer downhill stretches with the
brake/inching pedal pressed only halfway through!
Failure to observe this can cause serious injury or death.
►
Reduce the travel speed early enough before turning or downhill
machine travel.
►
Reduce engine speed: remove your foot from the accelerator pedal.
►
Brake the vehicle by braking intermittently. To do this: briefly press the
brake-inch pedal several times through the inch range.
►
Select the next lower speed
.
When braking the vehicle with the brake/inching pedal
oil pressure is
fed into the hydraulic trailer braking system and the trailer is braked.
The parking brake has no effect on the trailer braking system.
If the travel speed is reduced with brake-inch pedal
, oil pressure is
applied to the trailer braking system 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.
