OPERATING INSTRUCTIONS
Pre-Coupling of Semitrailer and
Tractor
1. Slowly back the tractor up to the front end of the
semitrailer so the
kingpin of the semitrailer is
centered between the tractor fifth wheel jaws. Stop
the tractor several inches ahead of the semitrailer.
Set tractor parking brake.
2. The king pin plate should be the same height as, or
slightly lower than, the latch area of the fifth wheel
plate of the tractor. If necessary, connect the tractor
hydraulic lines or start the trailer hydraulic power
engine. Use the
TRAILER TILT lever to raise or lower
the kingpin plate sufficiently to allow proper coupling
(See Figure 3-2.) Drain all air and moisture from the
tractor air brake system in accordance with the
tractor manufacturer’s instructions.
3. Connect the service and emergency air hoses of the
tractor to their respective gladhand on the front of the
semitrailer. The tractor’s air hose couplings are then
attached and locked to the appropriate gladhands;
the
red emergency line to the gladhand with the
“EMERGENCY” tag, and the blue service line to
the gladhand with the “SERVICE” tag (See
Figure 3-1.) Chock the semitrailer wheels before
activating the semitrailer air supply valve in the
tractor. Set the semitrailer brakes.
4. Check the air brake operations of the semitrailer as
follows:
a. Apply brakes and inspect brake action on all
wheels for prompt application.
b. Release brakes. All brakes should release
immediately. Air pressure should discharge
quickly from the relay emergency valve.
c. Disconnect the emergency air line from the
semitrailer gladhand. Semitrailer brakes should
promptly set.
d. Reconnect the emergency air line to the
semitrailer and activate the semitrailer air supply
valve. The semitrailer brakes should set.
Coupling of the Tractor to the
Semitrailer

DANGER
1. Verify the semitrailer wheels are chocked and brakes
function properly.
2. Make sure the tractor’s fifth wheel coupler is open.
3. Slowly back the tractor so its fifth wheel contacts the
front of the kingpin plate on the semitrailer and slips
under it. Continue backing until the fifth wheel
coupler locks onto the semitrailer kingpin.
4. Try to pull the tractor forward a few inches to verify
the vehicle coupling is secure. If the tractor
disconnects from the semitrailer: locate the source of
the coupling failure; repair before continuing; and
repeat
steps 3 and 4.

CAUTION
5. Check that the tractor couples securely to the
semitrailer before setting tractor and semitrailer
parking brakes.
IMPORTANT
Keep brakes engaged for remainder of coupling,
check-out, and parking.
Keep all personnel clear of front, rear, and sides
of tractor and semitrailer during coupling,
component operations, and uncoupling. Failure
to stay clear can result in serious personal injury
or death.
Pushing semitrailer backwards can damage
landing gear.
