WARNING!

IMPORTANT INFORMATION

This Trailer’s Hitch Coupler MUST be properly 

secured to the hitch ball of the towing vehicle.  

After assembly and attachment, pull up and down 

on the Hitch Coupler to make sure the hitch ball is 

fitting snugly in the Hitch Coupler.  There must be 

no play between the hitch ball and Hitch Coupler.  

If there is play, tighten the Adjustment Nut until no 

play is present.  If the Adjustment Nut is too tight, 

the Handle will not lock.  Carefully read and follow 

the complete instructions in this manual BEFORE 

setup or use.

IF THE COUPLER IS NOT SECURED PROPERLY, 

THE BALL COULD COME LOOSE WHILE 

THE TOW DOLLY  IS IN MOTION, POSSIBLY 

CAUSING PROPERTY DAMAGE, SERIOUS 

PERSONAL INJURY, AND/OR DEATH.
