Fifth Wheel Lock (Slider Adjustment) Switch
Vehicles having an air slide fifth wheel have a fifth wheel
slider lock controlled by a switch on the instrument panel.
By placing the switch in the unlock position, you can slide
the fifth wheel to various positions to adjust weight distri-
bution. There is a guard over this switch to protect you
against accidentally activating or releasing the lock.
WARNING! Do not move the fifth wheel while
the tractor-trailer is in motion. Movement of
the fifth wheel while a tractor-trailer is moving
can cause a serious accident involving death
or personal injury. Your load could shift sud-
denly, causing you to lose control of the vehi-
cle. Never operate the vehicle with the switch
in the unlock position. Always inspect the fifth
wheel after you lock the switch to be sure the
fifth wheel is engaged.
CAUTION: Both the fifth wheel plate and the
slide tracks (if a slider) should be cleaned and
lubricated periodically to ensure smooth turning
and sliding action. Failure to keep these sur-
faces lubricated can lead to frame or driveline
damage.
