All personnel must stand clear of towing vehicle and trailer during coupling operation. Failure to
follow this warning may result in serious injury or death to personnel.

Close pintle hitch (2). Check that locking latch is locked by pulling up on pintle hitch. Pintle hitch should not
come up. Install safety pin (1) into pintle hitch.
CAUTION
Safety chains must be attached on opposite sides of the trailer tongue or frame and crossed under
the tongue when passed forward to the towing vehicle so as to cradle the tongue in the event of a
breakaway. Slack should only be sufficient to permit full turns.

chains are too long, they can be twisted to be shortened. It is recommended that wire be used across the hook

permanent damage may occur.
