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 the 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 trailer is in motion, possibly
causing property damage, SERIOUS
PERSONAL INJURY, or DEATH.
Read this material before using this product.
Failure to do so can result in serious injury.
SAVE THIS MANUAL.
