PREPARING TO TOW
Rotate flip lock counter-clockwise and seat in groove.
Insert safety lynch pin and flip bail to secure.
Attach electrical harnesses.
Attach lanyard and insert electric brake break-away
plunger. If hydraulic surge brakes are present, attach
lanyard from the surge brake assembly as required.
Fully retract front trailer lifting jacks.
Close truck tailgate or reinstall tailgate as required.
Remove tire chock blocks.
Check running lights, directional signals
and brake lights for proper operation.
Pull forward a few feet and apply brakes to check
that trailer brakes are activating. Adjust the electric
brake controller if necessary.
When parking it may be necessary to unload the forces
on the kingpin by lightly backing against the kingpin.
This maneuver helps put the kingpin and 5th wheel in a
neutral position. Once parked on a firm and level surface,
set automatic transmission vehicles to park and activate
emergency brake, set standard transmission vehicles to
neutral and activate emergency brake.
Multiple wheel chocks should be used in front of
and behind trailer tires. Do not substitute objects
such as, but not limited to: stones, wood blocks, etc.
Disconnect as required all harnesses,
lanyards, safety devices, etc.
Do not extend rear trailer stabilizer jacks at this time.
Lower or remove truck tailgate as required.
Begin extending front trailer lifting jacks. Extend lifting jacks
just enough to remove the weight of the trailer from the 5th
wheel skid plate. Creating a gap between the trailer skid
plate and the 5th wheel skid plate is not necessary and is
not recommended. If a gap is present, it should be minimal
and no more than 1/16". Excessive gap while coupled can
damage internal components of the 5th wheel hitch as well
as components of your trailer.
Flip safety lynch pin bail and remove lynch pin.
Lift flip lock and pull lock bar outward approximately 1/2".
While holding lock bar in this position, drop flip lock back onto
the lock bar. Pull lock bar to its full extension. Flip lock will
drop and engage second groove. Release lock bar. Lock bar
should remain in full extended position. The red dot NOTE:
is visible (cab side) through lock bar guide tube. This signifies
that the jaws are not locked and are prepared to be uncoupled.
Flip lock to secure.
Slowly pull vehicle out from underneath trailer skid
plate. Observe that trailer is uncoupling. If resistance
is encountered, determine corrective action and repeat
uncoupling steps.
Once uncoupled from trailer, you may elect to reset 5th
wheel for future coupling at this time. To reset for future
coupling, lift the flip lock from its groove. This will allow the
lock bar to partially retract into its coupling position.
IMPORTANT: Failure to reset lock bar in this manner prior
to next coupling will not allow the jaws to lock around
the trailer's kingpin. See Figure 6 below.
