COUPLING TO THE TOW VEHICLE
• Rock the ball to make sure it is tight to the ball support, and visually check that the gooseneck
ball nut is solid against the lock washer and ball support frame.
WARNING
A loose gooseneck ball can result in uncoupling, leading to death or serious injury.
Make sure the gooseneck ball nut is tight before coupling the trailer.
• Wipe the inside and outside of the receiver clean and inspect it visually for cracks; and feel
the inside of the receiver for worn spots and pits. If any of these conditions exist, have the
receiver replaced before coupling the trailer.
• Lubricate the inside of the receiver with automotive bearing grease.
• Be sure the receiver is tight to the trailer. All receiver fasteners must be visibly solid against
the trailer frame.
• Release the jack handle or crank from its holder.
• Rotate the handle/crank clockwise to raise the bottom surface of the gooseneck to be above
the top of the gooseneck ball.
PREPARE THE BALL AND RECEIVER
• Release the lock plate on the gooseneck ball receiver. With the spring-loaded lock plate locking
pin in the OPEN position, rotate the lock plate to a position that allows the gooseneck ball to
enter the receiver.
• Slowly back up the tow vehicle so that the ball is aligned under the receiver.
WARNING
If the trailer drops during coupling, death or serious injury may result. There
must be no one under the trailer or coupler before or during the coupling operation.
COUPLE THE TRAILER TO THE TOW VEHICLE
• Rotate the jack handle counter-clockwise. This will retract the jack causing the receiver to
drop down so it can fully engage the ball and transfer the weight of the trailer tongue to the
towing vehicle hitch. If the receiver does not line up with the ball, raise the receiver again and
adjust the position of the tow vehicle. Then lower the receiver over the ball. When the drop leg
base is no longer resting on the ground, the towing vehicle hitch is holding all of the weight of
the trailer tongue.
• Close the lock plate on the receiver.
• Move the spring-loaded lock plate locking pin to the CLOSED position. Be sure the locking pin
is holding the lock plate.
• Be sure the receiver is all the way on the ball and the lock plate is engaged. A properly
engaged locking mechanism will allow the coupler to raise the rear of the tow vehicle. Using the
trailer jack, test to see that you can raise the rear of the tow vehicle by 1 inch.
