SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS

To avoid personal injury and/or property damage, do not exceed the Trailer’s

maximum weight capacity of 1,560 pounds.

Before each use, always examine the Trailer for proper Tire air pressure (60

PSI), 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.

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.

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.

Make sure the Coupler and the vehicle’s ball hitch (not included) are of equal

mating size (2”) and are rated equal to or greater than the weight of the Trailer

and its payload.

For technical questions, please call 1-800-444-3353.

Do not exceed 45 miles per hour when towing the Trailer. Excess speed is a

major cause of vehicle-trailer accidents. Poor road conditions, such as uneven, wet,

or unstable surfaces, will create further hazards if driven on too quickly. Reduce

speed to a safe level when driving in poor driving situations.

tion. If unreadable or missing, contact Harbor Freight Tools for a replacement.
