FIFTH WHEEL STARTING AND OPERATING THE VEHICLE
– 136 – Y53-6033
Regional Haul (R05/10)
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 acci-
dent causing death or personal injury. 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.
See page 252
for maintenance information.
