IMPORTANT SAFETY INFORMATION
Use Precautions
1. This product is not a toy. Do not allow
children to play with or near this item.
2. Use as intended only.
3. Inspect before every use; do not use
if parts are loose or damaged.
4. Do not exceed listed weight capacity.
Be aware of dynamic loading!
Sudden load movement may briefly create
excess load causing product failure.
5. Maintain product labels and nameplates.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
Product Specific Safety Precautions
1. Do not exceed the Gross Vehicle
Weight Rating of the truck.
2. Before each use, always examine the trailer (not
supplied) for: proper tire air pressure, damaged
tail lights, damaged side running lights, loose
bolts and nuts, structural cracks, bends, and any
other condition that may affect safe operation. Do
not use a trailer when minor damage appears.
3. Never allow adults, children, or
pets to ride in the trailer.
4. Before each use, always attach the safety chains
(not supplied) of the trailer to the towing vehicle.
Make sure the safety chain is attached to the towing
vehicle with the same length for each side. Do not
allow the safety chain to drag on the ground.
5. Verify that the payload being transported is
properly and safely secured in the trailer.
Load the trailer evenly from side to side with
60% of the load forward of the Axle.
6. The towing vehicle must be capable of towing the
trailer and its payload. Verify that the towing vehicle
hitch (not included) is capable of towing the weight
of the trailer and its payload. The towing capacity of
the hitch is typically stamped on the Hitch drawbar.
7. Make sure the Ball Coupler and the vehicle’s ball
hitch (not included) are of equal mating size (see
Specifications on page 2), and are rated equal to, or
greater than, the weight of the trailer and its payload.
8. Do not exceed 45 miles per hour when
towing a trailer. Excess speed is a major
cause of vehicle-trailer accidents.
9. Whenever possible, park the trailer on a flat,
level, paved, surface and chock both tires to
keep the trailer from accidentally moving.
10. Industrial applications must
follow OSHA requirements.
11. The warnings, precautions, and instructions
discussed in this manual cannot cover all possible
conditions and situations that may occur. The
operator must understand that common sense and
caution are factors, which cannot be built into this
product, but must be supplied by the operator.

Operation
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
1. Place Ball Coupler on trailer Tongue (not supplied).
See illustrations below. Tongue width (usually
marked on the Hitch) must exactly match with
width of the Ball Coupler (see “Specifications”
on page 2); otherwise, do not use.
2. Align holes in side of Ball Coupler to holes in trailer
Tongue. See illustrations Below. If no holes are
present, use Ball coupler as a template, mark Tongue
through holes and drill. Be certain that Ball Coupler
is well seated on hitch before marking for drilling.
Note: Before drilling, check for hidden wires in the drilling
path. If you are not familiar with drilling and mounting the
Ball Coupler, have a qualified service technician do it.
3. Acquire two SAE Grade 5 or Metric Grade 8.8
steel bolts the same diameter as the holes in
the Ball Coupler, and 1/2 inch longer that the
width of the Ball coupler. Also acquire two flat
washers, and two lock nuts (not included).
4. Place Bolts through Ball Coupler holes and secure
from other side first with flat washer, then lock nut.
Securely tighten with a wrench (not included).

5. To reduce friction between Tongue ball
and Coupler, apply a layer of heavy
weight grease over the Tongue ball.
6. Pull up on Trigger and lift up on Handle.
7. With assistance, place Ball Coupler over the
vehicle’s Tongue ball, pull back on Trigger and
push down on Handle until Trigger locks in the slot.
Pull up and down on Coupler to make sure Tongue
ball is fitting snugly in Coupler. There should be
no play between Tongue ball and Ball Coupler.
8. Attach a Safety Pin and “R” Pin (not included).
9. Attach each side of the Safety Chain (not included)
equally to the towing vehicle’s rear bumper or frame.
NOTICE: If there is play, tighten Adjustment Nut until no
play is present. If Adjustment Nut is too tight, the Handle
will not lock. Failure to properly adjust can result in
uncoupling. After Adjustment Nut is properly adjusted,
pull back on Trigger and push down on Handle until
Trigger locks in slot. Pull up on Handle firmly to make
sure Trigger is locked in place and Handle cannot move.
