SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS  
1.  
2.  
To avoid personal injury and/or property damage, do not exceed the Trailer’s maxi-  
mum weight capacity of 1,740 pounds (evenly distributed).  
Before each use, always examine the Trailer for proper Tire air pressure (maximum  
pressure is 80 PSI cold), damaged tail lights, damaged side running lights, loose  
bolts and nuts, structural cracks and bends, and any other condition that may affect  
its safe operation. Do not use the Trailer even if minor damage appears.  
3.  
4.  
Never allow adults, children, or pets to ride in or play on the Trailer.  
Before each use, always attach the Safety Chain 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.  
6.  
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.  
Prior to using the Trailer, make sure to read and understand all instructions and  
safety precautions as outlined in the owner’s manual for the towing vehicle. 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 and the vehicle’s ball hitch (not included) are of equal mat-  
ing size (2”) and are rated equal to or greater than the weight of the Trailer and its  
payload.  
8.  
9.  
Do not exceed 45 miles per hour when towing the Trailer. Excess speed is a major  
cause of vehicle-trailer accidents.  
The Tail Light 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 elec-  
trical current.  
10.  
Whenever possible, park the Trailer on a flat, level, paved, surface and chock both  
Tires to keep the Trailer from accidently moving.

the Trailer on a straight path. If the Trailer is allowed to turn off the straight path  
while backing up, the Trailer could jackknife, causing severe damage to the Trailer  
and towing vehicle.  
12.  
13.  
Maintain labels and nameplates on the Trailer. These carry important information.  
If unreadable or missing, contact Harbor Freight Tools for a replacement.

turer, Changzhou Nanxiashu Tool Company. If NHTSAreceives 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 can not  
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 1-800-424-9393 or 202-366-0123 or write NHTSA, U.S. Department, 400

TIRE CARE  
Checking Tire Pressure  
Note: Underinflated tires can decrease handling, stopping performance, traction, tire life,  
and load-carrying capability, in addition to causing other negative and hazardous  
effects, including tire failure. Overinflated tires are at greater risk of an impact break,  
where the tread and casing break when striking a hard edge, often opening a huge  
gash across the tread. Incorrect inflation pressure also increases tires wear rate.  
Therefore, it is important to keep tires inflated properly.  
Check all tires’ pressure at least monthly, due to the following factors:  
• Most tires naturally lose air gradually.  
• Tires can suddenly lose air if the tire strikes a pothole, curb, or other object.  
• It is usually not possible to determine underinflation of radial tires by visual in-  
spection.  
This vehicle has 80 PSI recommended cold tire inflation pressure. The term “cold”  
in this manual does not refer to the temperature outside, but it refers to the fact that a tire  
that has not been driven for a period is cooler (and therefore has lower pressure) than a  
tire that has been driven on. Tires heat up while being driven on. To check (or fill to) a  
tire’s cold inflation, the tire must have not been driven for more than a mile or two for at  
least three hours. If you check a tires pressure when it is not “cold”, the pressure will ap-  
pear higher than the actual cold tire inflation.  
Steps for Maintaining Proper Tire Pressure  
1.  
Locate the recommended tire pressure on the vehicle’s tire information placard,  
certification label, or in the owner’s manual. This trailer has 80 PSI recommended  
cold tire inflation pressure.  
2.  
3.  
Measure and record the tire pressure of all tires.  
If the tire pressure is too high in any of the tires and the tires have not been driven  
for at least three hours, slowly release air by gently pressing on the tire valve stem  
with the edge of your tire gauge until you get to the correct pressure. If the vehicle  
have been driven within the past three hours and the tire pressure is too high on any  
tires, then recheck the pressure once the tires have been allowed to sit motionless  
for at least three hours.  
4.  
If the tire pressure is too low, note the difference between the measured tire pres-  
sure and the correct tire pressure. These “missing” pounds of pressure are what  
you will need to add.  
5.  
6.  
At a service station, add the missing pounds of air pressure to each tire that is  
underinflated.  
Check all the tires to make sure they have the same air pressure.

7.  
If the tirespressure was not measured “cold”, then the pressure should be rechecked  
with the tires cold as soon as possible.  
Tire Size  
To maintain safety, only purchase new tires of the same size as the original tires.  
Look at the Tire and Loading Information Placard, the Specifications Chart in this manual,  
or the sidewall of the tire being replaced. If you have any doubt about selecting the cor-  
rect size, consult a tire dealer.  
Tire Tread  
The tire tread provides traction that prevents your vehicle from slipping, especially  
if the road is wet or icy. Tires are unsafe and should be replaced when the tread is worn  
down to 1/16”. Measure tread depth using a tread depth indicator (not included).  
Tire Rotation  
Every 5,000 miles the left and right tires should be switched. This will cause the  
tires to wear more evenly and last longer.  
Tire Balance and Alignment  
The tires need to be balanced to prevent vibration when driving. This involves  
attaching small weights to the rim to offset small differences in rim and tire weight. The  
tires also need to be aligned properly. Alignment is the orientation of the tires to the road  
surface and their being parallel. This helps the tires to wear evenly, and provide better  
traction. Both tire balance and alignment require specialized equipment that is not pro-  
vided with this vehicle.  
Tire Repair  
To properly repair a punctured tire, the hole needs to be properly plugged and  
patched from the inside of the tire. Tread punctures can be repaired if they are not too  
large. Sidewall punctures should not be repaired, the tire needs to be replaced if the  
sidewall is damaged. Tires should be removed from the rim to be inspected before being  
plugged and patched. A qualified mechanic should remove the tire from the rim, perform  
the repair, and remount the tire.

VEHICLE LOAD LIMIT  
Steps for Determining Correct Load Limit  
1.  
Locate the statement “The weight of cargo should never exceed XXX pounds” on  
your vehicle’s placard.  
2.  
3.  
That figure equals the available amount of cargo and luggage load capacity.  
Determine the combined weight of luggage and cargo being loaded on the vehicle.  
That weight may not safely exceed the available cargo and luggage load capac-  
ity.  
4.  
If the trailer’s load exceeds the cargo and luggage load capacity, then the trailer  
be unsafe resulting in hazardous effects, such as: Trailer’s tires will not be able to  
maintain traction properly, and stopping distance will be increased significantly.
