DRIVING TIPS AND TECHNIQUES STARTING AND OPERATING THE VEHICLE
– 136 – Y53-6008A
Medium Duty (R05/09)
WARNING! Do not move of the fifth wheel
while the tractor-trailer is in motion. Your load
could shift suddenly, causing you to lose con-
trol of the vehicle, which can result in a seri-
ous accident. 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 lock is
engaged.
Fifth Wheel Lubrication
• Frequently operate and lubricate movable or sliding
fifth wheels to prevent corrosion.
CAUTION: Both the fifth wheel plate and the
slide tracks (if a slider) should be cleaned and
lubricated periodically to ensure smooth turn-
ing and sliding action. Failure to keep these
surfaces lubricated can lead to frame or drive-
line damage.
