Important Trailer Safety Information
Trailer Ball & Couplers
WARNING: Failure to properly engage the hitch ball
in the coupler ball socket and securely lock the
coupler latch mechanism can cause the trailer to
become detached from the tow vehicle while trav-
eling, which may cause serious injury or property
damage.
AVERTISSEMENT : Le non-respect d'engager
correctement la boule d'attache dans la cavité de la
boule de l'attelage et de verrouiller solidement le
mécanisme du loquet de l'attelage pourrait mener
la remorque à se détacher du véhicule remorqueur
pendant le déplacement, ce qui pourrait causer des
blessures graves ou des dommages à la propriété.
Ball diameter for which rating (GVWR) shall not exceed
the gross trailer weight marked on the trailer coupler.
The hitch balls have the rated load they are capable of
towing stamped Into the top of the ball.
Make sure the ball that you use to tow your trailer has
the same capacity rating as the coupler.
Do not use a different size ball than the size the coupler
is designed to use.
Before Towing:
Check mounting bracket hardware for wear and proper
tightness. Replace bent, broken, or worn hardware.
Tighten hardware to 90-96 ft. lbs. Use only the
hardware provided with the Trailer. If replacement
hardware is needed, order replacement kit 8.924-
356.0.
Make sure that the trailer safety chains are properly
connected to the towing vehicle and trailer according to
SAE J684. See Safety Chain information in your
manual.
Make sure that all trailer lighting is hooked up and
working properly.
Warning: Failure to follow all installation instructions
could result in coupler failure.
Variable Height Bracket:
Coupler operation must not be impaired in any way. Do
not use if coupler operation is impaired.
Bolting Instructions:
Align holes in coupler and mounting bracket. NOTE:
Coupler must be secured to mounting bracket using
two sets of holes in the mounting bracket. Insert two (2)
5/8”x4.5”, grade 5 bolts through desired mounting
bracket holes and coupler. For each bolt, Place one (1)
washer at the bolt head side and another at the bolt
thread side before assembling the nuts. Tighten lock
nuts to 90-96 ft. lbs. After installation, ensure coupler
operation is not impaired in any way. Do not use if
coupler operation is impaired. The hardware provided
with the trailer has a self-lubricating coating which is
taken into account for the tightening torque above, and
is lower than standard hardware and also is more
consistent with re-torque specifications to first-torque
than standard hardware. Order replacements with the
8.924-356.0 replacement kit, or consult your hardware
vendor for applicable, higher, torques for the
application.
Maintenance
Keep ball pocket and mechanism clean. The following
procedures should be performed at least annually:
Check set screw torque Grease ball pocket
Oil pivot points with SAE 30 wt. motor oil
Inspect retaining pin and replace if necessary
Operation
To Couple:
1. Block trailer wheels.
2. Align hitch ball beneath coupler.
3. Open coupler locking lever. While holding locking
lever open, lower the coupler over the hitch ball
until ball is fully seated into the ball pocket.
4. If locking lever is pinned open, remove pin. Move
locking lever to the closed position. Check that the
latch is engaged by lifting up on back of locking
lever. Also, check that the hitch ball is fully seated
and ball clamp is below the ball. If the ball is not
seated with lever in the closed position and latch
engaged, DO NOT TOW.
