WARNING
W h e n towing the semitrailer with M818, M931 series, or M932
s e r i e s the fifth wheel wedges must be in the locked-in (pushed
i n ) mode for highway and secondary road use, and in the
locked-out (pulled out) mode for cross country operation.
Extreme caution shall be exercised in all turns, curves, and
h i g h w a y cloverleafs when towing a high center of gravity
containerized load.
WARNING
Under no circumstances shall speeds exceed the following:
Highway . . . . . . . . ....... ...... . . . . . . . . . .... 55 mph
Gravel/Dirt . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 mph
O f f - R o a d . . . . . . . . .... ..... . . . . . . . . . .. 10 mph
Failure to observe these warnings may result in personnel
i n j u r y and damage to equipment.
( 1 ) D r i v i n g . When driving the towing vehicle and semitrailer, the overall
l e n g t h 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. The semitrailer's payload will affect stopping and off-road
maneuverability.
(2)
Turning. When turning corners, allow for the semitrailer wheels turning
inside the radius of the towing vehicle. Make a right turn by driving the
towing vehicle about halfway into the intersection, then cutting sharply
to the right. This will keep the semitrailer off the curb.
