locking lever, or use a padlock for added security.
6. Check that the coupler is securely attached to the ball
hitch.
To uncouple the trailer from the tow vehicle:
1. Remove the locking pin (or padlock, if used) from the
hole in the locking lever.
2. Pull the locking trigger upward and lift the locking lever.
