th
Wheel

OPERATING CAUTIONS:
1. Keep all people away from the front, back and sides of the tractor/trailer when
coupling, raising, lowering or moving the vehicle. Keep all parts of your body away from
all moving parts.
Keep workers away from the back of the trailer near dock doors or other areas when
operating the
5
th
wheel.
2. Be sure that the tractor is locked to the trailer. Make sure that the fifth wheel is
securely locked before attempting to move the tractor/trailer.
3. Be sure that the lifting
5
th
wheel is ABOVE the level of the trailer king pin plate before
attempting to couple. The
5
th
wheel should be several inches above the trailer king pin
plate.
Because the
5
th
wheel may be lower or higher than the standard
5
th
wheels that you may
now be using, you must be sure that the
5
th
wheel is raised slightly before attempting to
couple to any trailer.
4. Do not push the king pin Jaw control valve until you want to release the trailer. As
soon as you push down this valve, the trailer will drop.
5. Before traveling on public roads, put the Road Lock into a ‘locked’ position. Do not
pull a trailer on public roads unless the road lock is in the locked position.
6. Engage the PTO only when lifting. Take the PTO out of gear when not lifting. Do not
move the tractor trailer with the PTO in gear. Leaving the PTO in gear when not lifting
will cause damage to the pump and PTO
