SAFETY GUIDELINES — TRAILERS
SAFETY CHAINS
If the coupler connection comes loose, the safety chains
can keep the trailer attached to the tow vehicle. With
properly rigged safety chains, it is possible to keep the
tongue of the trailer from digging into the road pavement,
even if the coupler-to-hitch connection comes apart.
JACKSTAND
A device on the trailer that is used to raise and lower the
coupler. The jack is sometimes called the “landing gear” or
the “tongue jack”.
COUPLER TYPES
The GBX24S and GBX24B come standard with a 2" ball
coupler.
BALL COUPLER
A standard 2" ball coupler (Figure D) connects to a 2" ball
hitch normally located on the bumper of the tow vehicle. All
ball couplers come with a locking latch atop the coupler that
must be engaged to ensure that the hitch ball is securely
locked to the trailer coupler.
Figure D. Ball Coupler
Before each tow, coat the ball with a thin layer of automotive
bearing grease to reduce wear and ensure proper operation.
Check the locking device that secures the coupler to the
ball for proper operation.
If you see or feel evidence of wear, such as fl at spots,
deformations, pitting or corrosion, on the ball or coupler,
immediately have your dealer inspect them to determine
the proper action to prevent possible failure of the ball and
coupler system. All bent or broken coupler parts must be
replaced before towing the trailer.
The coupler handle lever must be able to rotate freely and
automatically snap into the latched position. Oil the pivot
points, sliding surfaces, and spring ends with SAE 30W
motor oil. Keep the ball socket and latch mechanism clean.
Dirt or contamination can prevent proper operation of the
latching mechanism.
The load rating of the coupler and the necessary ball size
are listed on the trailer tongue. You must provide a hitch
and ball for your tow vehicle where the load rating of the
hitch and ball is equal to or greater than that of your trailer.
Also, the ball size must be the same as the coupler size. If
the hitch ball is too small, too large, is underrated, is loose
or is worn, the trailer can come loose from the tow vehicle
and may cause death or serious injury.
THE TOW VEHICLE, HITCH AND BALL MUST HAVE A
RATED TOWING CAPACITY EQUAL TO OR GREATER
THAN THE TRAILER
Gross Vehicle Weight Rating
(GVWR). IT IS ESSENTIAL THAT THE HITCH BALL BE
OF THE SAME SIZE AS THE COUPLER.
The ball size and load rating (capacity) are marked on the
ball. Hitch capacity is marked on the hitch.
WARNING
Coupler-to-hitch mismatch can result in uncoupling,
leading to death or serious injury.
Be sure the LOAD RATING of the hitch ball is equal or
greater than the load rating of the coupler.
Be sure the SIZE of the hitch ball matches the size of
the ball coupler.
