WARNING
Do not use the trailer air supply for parking trail-
ers not equipped with spring parking brakes.
This applies the trailer service brakes only. As air
bleeds from the trailer brake system, brake appli-
cation is lost. This could allow the unattended
vehicle to roll away, possibly resulting in serious
personal injury or death.
2.
Chock the front and rear tires of the trailer.
3. Disconnect the trailer air and electrical lines.
Plug the air lines to keep them free of dirt.
4. Take the weight of the trailer drawbar off the
pintle hook.
5. Open the latch by first removing the cotter pin,
then lift up the lock and raise the latch.
6. Slowly drive the vehicle away from the trailer.
Premier Trailer Couplings
General Information
IMPORTANT: Before operating the Premier cou-
pling, refer to the Premier web site at
www.premier-mfg.com for complete safety,
operation, and maintenance instructions.
Trailer couplings are attached to the rear closing
crossmember. The Premier trailer couplings
(
Fig. 18.3 ) are designed for use with trailers having a
maximum gross weight of 100,000 lbs (45 455 kg).
The Premier 2200 and 2400 trailer couplings are air
adjusted couplings with a rigid pintle hook, attached
to the rear closing crossmember. An air chamber,
mounted forward of the coupling, operates a push
rod, which pushes against a shoe inside the cou-
pling. The shoe maintains constant pressure on the
eye of the trailer drawbar when it’s over the pintle
hook. This takes up any slack in the trailer connec-
tion, providing smoother towing and less wear on the
pintle hook. The air pressure is activated when the
trailer brakes are released.
Trailer Hookup
1. Chock the trailer tires.
2.
Push the latch lock towards the mounting plate
as far as possible then, while holding the latch
lock in place against the mounting plate, pull the
top of the latch as far as possible toward the
pintle hook.
3. While holding the latch in place, release the latch
lock.
4. Back the vehicle up until the drawbar eye is over
the pintle hook, then lower the trailer.
5. Pull the top of the latch as far as possible toward
the pintle hook then, while holding the latch in
position, push the latch lock towards the mount-
ing plate.
6.
While holding the latch lock in place against the
mounting plate, release the latch.
7.
Release the latch lock and make sure it is fully
seated in the slot on top of the latch.
NOTICE
Always make sure the connection hanger keeps
the trailer air hoses and electrical cables posi-
tioned so that they do not rub on anything. Rub-
bing may wear through hoses or cables, resulting
in air leaks, or exposed or broken wires, poten-
tially affecting trailer brake or electrical systems.
8. Connect the trailer’s electrical and air lines.
Trailer Release
1. Apply the truck and trailer parking brakes.
