How To Attach The Trailer
To connect the trailer to the tow vehicle, open the coupler mecha-
nism (instructions below). When necessary, raise the trailer jack. 
Slowly back up the tow vehicle until the hitch ball is under the cou-
pler. This is easier to perform with another person standing beside 
the trailer and guiding the driver.
Do not move the trailer to the tow vehicle. When the trailer is 
moved without a tow vehicle, the brakes do not work.
If the latch accidentally opens, the coupler could detach from the 
hitch ball. The hitch pin should fit easily into the hole. If it does not, 
the coupler latch is not completely closed. Every time the coupler is 
attached to the hitch ball, be sure the coupler completely covers the 
hitch ball and the lift handle will not open. If the hitch pin is damaged 
or lost, contact an authorized MasterCraft dealer to purchase a 
replacement pin.
You must install either the hitch pin that is supplied or a padlock 
(1/4” or 5/16” shank) into the hitch pin hole before towing to pre-
vent the coupler latch from accidentally opening.
To Open The Coupler
Remove the hitch pin from the hole in the side of the coupler. Slide 
the lock/latch rearward which should allow the latch to spring 
upward. The coupler should unlatch easily. If not, the ball may be 
over-sized or egg-shaped, 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 the rig is 
not parked downhill. Correct these conditions, and 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  
latch and slide the lock forward.
