314 OPERATION
If the fifth wheel is equipped with a sliding mounting, follow the advisory labels
attached to the component. Also, read the literature provided by the manufacturer.
DANGER
Always keep the fifth wheel plate well
lubricated to prevent binding between
the tractor and trailer. A binding fifth
wheel could cause erratic steering and
loss of vehicle control that may result in
serious personal injury or death.
There are three operating positions for the fifth wheel locking mechanism (ASF fifth
wheel is shown as a typical fifth wheel):
Locked
— This is the position that the fifth wheel will be in with a trailer hooked
up. In the locked position, the operating rod is retracted and the safety latch will
freely swing back and forth.
W9000180
Lockset
— This is the position the fifth wheel is in when uncoupling the trailer. To
achieve the lockset position, the operating rod is pulled out with a slight upward
motion. The operating rod shoulder will catch on the plate casting. The safety latch is
rotated toward the rear of the fifth wheel.
