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.
Repeat the above steps.
5) OPTIONAL: Place a 5/16” pin or lock in hole shown
To Uncouple:
1) Block trailer wheels.
2) Open locking lever. While holding locking lever fully
open, raise trailer off of hitch ball.
NOTE: A 5/16” diameter pin can be used to hold the
locking lever open.
Hitch Coupler Troubleshooting
If the coupler becomes damaged it must be repaired
or replaced before towing. When the coupler is placed
on the ball, the latch should close firmly. Keep the latch
mechanism lightly oiled and clean. Items to check for are
as follows:
1. Latch does not grasp ball securely:
•
Check the ball size. Make sure the ball and
coupler are the same size.
2. Latch does not snap into full latch position:
•
Check adjustment. Latch mechanism may be
too tight.
•
Check to see that the coupler housing has not
been damaged, keeping the ball hitch from fitting
completely into the housing as designed.
3. Keep the tongue blocked up when not in use so the
coupler and mechanism are not in the ground being
exposed to dirt and moisture.
4. Apply a small amount of an automotive grease to the
ball before hitching coupler to prevent wear of the two
parts during towing.
5. Make sure the latch safety pin is in position before
towing.
Coupler & Ball Engagement
If the coupler and towing ball resist attempts to make
engagement, do not force latch assembly. Instead, check
the ball diameter to verify that it conforms to Society of
Before Towing:
Check mounting bracket hardware for wear and proper
tightness. Replace bent, broken, or worn hardware.
Tighten hardware to 75-94 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
