LS600 PUMP — TRAILER SAFETY GUIDELINES
Coupler Types
The trailer is shipped from the factory with a 2-inch ball
coupler.
Ball Hitch Coupler
A ball hitch coupler (Figure 52) connects to a ball that is
located on or under the rear bumper of tow vehicle. This
system of coupling a trailer to a tow vehicle is sometimes
referred to as “bumper pull.”
A ball hitch trailer may be fitted with a tongue jack that can
raise and lower the coupler. The tongue jack is mounted to
the A-frame (front, or tongue) part of the trailer. By rotating
the jack handle clockwise, the jack will extend and raise
the tongue of the trailer.
Figure 52. Ball Hitch Coupler
Adjustable Tongue
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 flat 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.
When replacing a ball, the load rating must
match or exceed the GVWR of the trailer.
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.
WARNING
-
Hitch Ball Load Rating
Before coupling the tow vehicle to the trailer,
be sure the size and rating of hitch ball
match the size and rating of the coupler.
Hitch balls and couplers are marked with their
size and rating.
