3-6.2
Monitor the air pressure gauge on the
dash of the towing vehicle. Pressure should
not fall below 90 psi at any time.
3-6.3
The semitrailer wheels track to the in-
side of the towing vehicle during turns. Thus,
turning corners requires a wide swing to pre-
vent “curb hopping”, and to allow the semi-
trailer wheels to clear any obstacle on the in-
side of the corner.
3-6.4
To stop, use a gradual and smooth ap-
plication of brakes. If grabbing occurs, apply
less pressure - grabbing brakes are not effi-
cient.
WARNING
ALWAYS CHECK BEHIND AND UNDER
THE TRUCK AND SEMITRAILER FOR
PERSONS OR OBJECTS BEFORE
MOVING. FAILURE TO CHECK CAN
LEAD TO SERIOUS PERSONAL IN-
JURY OR DEATH TO OTHERS, OR
DAMAGE TO PROPERTY.
3-6.5
Backing should be done with care. Tail
overhang, semitrailer length, and allowable
space must be taken into consideration when
backing the semitrailer.
