3.3.2.1. Before coupling the trailer to the tow vehicle
Coupler-to-hitch mismatch can result in uncoupling, leading to death or
serious injury.
Be sure the LOAD RATING of the hitch ball is equal or greater than the load
rating of the coupler.
Be sure the SIZE of the hitch ball matches the size of the coupler.
Wipe the hitch ball clean and inspect it visually and by feel for flat spots, cracks and pits.
A worn, cracked or corroded hitch ball can fail while towing, and may result in
death or serious injury.
Before coupling trailer, inspect the hitch ball for wear, corrosion and cracks.
Replace worn or damaged hitch ball.
Rock the ball to make sure it is tight to the hitch, and visually check that the hitch ball nut is solid
against the lock washer and hitch frame.
Wipe the inside and outside of the coupler clean and inspect it visually for cracks and
deformations; feel the inside of the coupler for worn spots and pits.
Be sure the coupler is tight to the tongue of the trailer. All coupler fasteners must be visibly solid
against the trailer frame.
A loose hitchball nut can result in uncoupling, leading to death or serious
injury.
Be sure the hitch ball is tight to the hitch before coupling the trailer.
Raise the bottom surface of the coupler to be above the top of the hitch ball. Use the jack if one
is provided; otherwise, use wood or concrete blocks to support the trailer tongue.
Prepare the coupler and hitch
Lubricate the hitch ball and the inside of the coupler with a thin layer of automotive bearing
grease. If your trailer is equipped with a jack, raise the coupler above the ball height.
Open the coupler locking mechanism. Ball couplers have a locking mechanism with an internal
moving piece (ball clamp) and an outside handle, wheel, or latch.
In the open position, the coupler is able to drop fully onto the hitch ball.
See the coupler instructions for details of placing the coupler in the "open" position.
Slowly back up the tow vehicle so that the hitch ball is near or aligned under the coupler, if the
trailer jack has raised the coupler.
Couple the trailer to the tow vehicle
If your trailer does not have a jack, you will have to lift the coupler and place it over the ball.
