WARNING!
IMPORTANT INFORMATION
This trailer’s Hitch Coupler MUST be
properly secured to the hitch ball of the towing
vehicle. After assembly and attachment, pull
up and down on the Hitch Coupler to make
sure the hitch ball is fitting snugly in the Hitch
Coupler. There must be no play between the
hitch ball and the Hitch Coupler. If there is
play, tighten the Adjustment Nut until no play
is present. If the Adjustment Nut is too tight,
the Handle will not lock. Carefully read and
follow the complete instructions in this
manual BEFORE setup or use.
If the coupler is not secured
properly, the ball could come loose
while the trailer is in motion, possibly
causing property damage, SERIOUS
PERSONAL INJURY, or DEATH.

SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS
1. TO AVOID PERSONAL INJURY AND/OR PROPERTY DAMAGE, DO NOT
EXCEED THE TRAILER’S MAXIMUM CAPACITY PAYLOAD OF 1,090 LBS.
2. BEFORE EACH USE, ALWAYS EXAMINE THE TRAILER FOR PROPER
TIRE (16) AIR PRESSURE, DAMAGED TAILLIGHTS (29, 29A), DAMAGED
SIDE RUNNING LIGHTS (30), LOOSE BOLTS AND NUTS, STRUCTURAL
CRACKS, BENDS, AND ANY OTHER CONDITION THAT MAY AFFECT ITS
SAFE OPERATION. Do not use the Trailer even if minor damage appears.
3. NEVER ALLOW ADULTS, CHILDREN, OR PETS TO RIDE IN THE TRAILER.
4. BEFORE EACH USE, ALWAYS ATTACH THE SAFETY CHAIN (25) 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. ALWAYS CHECK TO MAKE SURE 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 (12).
6. MAKE SURE THE TOWING VEHICLE IS CAPABLE OF TOWING THE TRAILER AND
ITS PAYLOAD. Make sure the hitch on the towing vehicle is capable of towing the Trailer
and its payload. The towing capacity of the hitch is typically stamped on the hitch drawbar.
7. MAKE SURE THE COUPLER (23) AND THE VEHICLE’S BALL HITCH (not
included) ARE OF EQUAL MATING SIZE (1-7/8″) 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 THE TRAILER.
Excess speed is a major cause of vehicle-trailer accidents.
9. THE TAILLIGHT BULBS SUPPLIED WITH THIS TRAILER ARE FOR
A 12 VOLT DC ELECTRICAL SYSTEM ONLY. Do not attempt to power
the Light Bulbs with any other type or voltage electrical current.
10. WHENEVER POSSIBLE, PARK THE TRAILER ON A FLAT, LEVEL, PAVED, SURFACE
AND CHOCK BOTH TIRES TO KEEP THE TRAILER FROM ACCIDENTLY MOVING.
11. TRAILER LICENSING NOTICE: Some states may consider this Trailer a vehicle
requiring registration, licensing, and titling. Check with your State Department of Motor
Vehicles for information and guidance on registering, licensing, and titling the Trailer.

12. MAINTAIN LABELS AND NAMEPLATES ON THE TRAILER. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
13. REPORTING SAFETY DEFECTS: If you believe your vehicle has a defect which could
cause a crash or could cause injury or death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA) in addition to notifying the manufacturer,
Changzhou Nanxiashu Tool Company. If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety defect exists in a group of vehicles, it
may order a recall and remedy campaign. However, NHTSA cannot become involved in
individual problems between you, Harbor Freight Tools, or the manufacturer. To contact
NHTSA, you may either call the Auto Safety Hotline toll-free at 424-9393 or 202-366-0123
or write NHTSA, U.S. Department, 400 7th Street SW NSA-11, Washington, D.C. 20590.
