3.On optional ball couplers, always insert hitch safety pin before towing.

4.Make sure hitch and ball are properly sized and match each other.

WHEELS MUST BE CHOCKED when trailer is uncoupled from vehicle.

1.Chock in direction of grade.

2.Position chock snugly behind tire.

3.Place chock square to the tire.

4.Tap chock into place.

5.For added protection, chock both sides of tire.

INCORRECTLY WORKING LIGHTS can cause accidents.

1.State and Federal regulations require trailers used on highways to have tail, stop, turn, and side marker lights.

2.Lights are not required for trailers designed for off-road use only.

3.Check all lights and connectors for proper installation and operation before using the trailer.

4.Check condition of wiring harness leads, plugs, and connections regularly. Repair or replace damaged parts or wires.

5.Replace any broken lenses, reflectors, or bulbs.

INCORRECT TORQUE on lug nuts or INCORRECT TIRE PRESSURE or BEARING MAINTENANCE can cause loss of control resulting in serious injury and equipment damage.

1.Recheck lug nut torque after first 50 miles (80 km) and once each year or every 12,000 miles (19,500 km) thereafter, whichever comes first.

2.When checking lug nuts, keep them clean, dry, and unlubricated.

3.Check and repack wheel bearings once each year or every 12,000 miles (19,500 km), whichever comes first.

4.Maintain correct tire pressure according to sidewall data on tire – underinflation is the most common cause of tire trouble.

5.Check tires for wear every six months.

6.Use only replacement tires of the same size, rating, and capacity.

4.Do not wrap cable around safety chains, tongue, wiring, or any other parts.
