1. Visually inspect the hinge assembly for cracks,
impact damage and/or deformation before
each and every use. Do NOT use if any of
these conditions exist.
2. Over time, slack may develop in the hinge
assembly due to normal bushing wear.
Therefore, clean and inspect every 90 days or
sooner if your application dictates, and adjust
or replace the bushings if slack is noted.
3. To check for bushing wear, place a crowbar
near the center of the bracket adjacent to
the housing. Apply pressure to the bar and
visually test for free-play between either the
bushing & the housing or the bushing & the
taper pin. If free-play is noted tighten and/or
replace bushing.
NOTE: Pulling forward or backward while the
trailer brakes are set is not an acceptable
method to check for bushing wear.
4. This product is designed to be operated
within the free rotation limits of the coupling to
drawbar eye connection. It is the responsibility
of the vehicle designer/end user to ensure that
these limits are not exceeded (do not bind-up/
jackknife).
5. WARNING: Prior to towing, make certain that
adequately rated safety chains have been
properly connected.
6. Never weld on any Premier part in order to
repair damaged or worn areas. Field and/or
shop weld repairs are inadequate and may
further weaken the hinge assembly.

- Never attempt weld repair of damaged or worn components
- Clean and inspect hinge assemblies for damage or excessive wear before
each and every use
- All welds should be performed by a certified welder skilled in structural
welding practices
- The mounting structure the hinges are welded to must be of sufficient strength to
withstand load ratings of hinges
- Do not bind-up (Jackknife) any application as stresses can cause damage to products
