To open the coupler:
Remove the hitch pin from the hole in the side of
the coupler. Push the button on top of the hand to the
side. While holding the button to the side, raise the
handle by lifting the front with two fingers. The coupler
should unlatch easily. If not, the ball may be over-sized
or egg-shaped, or foreign matter could be lodged in the
coupler ball socket, or the coupler is pushing on the
hitch ball. Check to make sure the wheel on the tongue
jack is raised or that you are not parked downhill. Cor-
rect these conditions, then try to open the handle. Also
if the tongue jack is forcing the front of the trailer up or
the trailer is pushing against the tow vehicle, it can also
result in failure of the coupler to open properly.
To close the coupler:
Place the coupler over the ball, lower the coupler
and close the handle. An audible “click” will be heard.
The handle should close with finger pressure. If the
handle will not close freely, the ball is not fully inserted
into the socket, it is over-sized or egg-shaped. DO NOT FORCE THE HANDLE. If neces-
sary, replace the ball with a quality unit that meets SAE specifications.
Insert the hitch pin into the hole on the side of the coupler.
DO NOT tow the trailer with the handle
open or if the latch handle will not re-
main closed. Check to see if the coupler is
locked. Li on the handle without push-
ing the button to the side. If the handle
opens, the hitch ball is not the right size, shape or the latch parts have been
damaged. If the latch is damaged, contact an authorized MasterCra dealer
for assistance.
