When driving the tractor and semitrailer, the overall length of the unit must be kept in mind when passing other vehicles
and when turning. Because the unit is hinged in the middle, backing is also affected.
When turning corners, allow for the fact that the semitrailer wheels turn inside the turning radius of the tractor. Make a
right turn at a road intersection by driving the tractor about halfway into the intersection and then cut sharply to the right.
This will keep the semitrailer off the curb.
The brakes of the tractor and the semitrailer are applied at the same time in norrnal operation when the driver steps on
the brake pedal. Brake pressure must be applied gradually and smoothly. The semitrailer brakes may be applied
separately by using the semitrailer handbrake control lever on the steering column. On steep downgrades or slippery
surfaces, the semitrailer brakes must be applied before the tractor brakes. This will reduce the possibility of jackknifing
When parking tractor and semitrailer to leave unattended, set parking brake on tractor, and turn off engine before
leaving cab. Block the semitrailer wheels with chock blocks (1). Block in front of the outer forward wheel and tire
assembly (2), and behind the outer rear wheel and tire assembly (3).
