Towing Safety Checklist
Inspect the trailer for loose bolts and worn parts. Tighten loose bolts and replace worn parts before hooking up. If you have bolts that are consistently coming loose, use Loctite or put on a double nut to keep them tight.
During hook up:
Each time you stop, check the hitch and cables to make sure they are still properly attached. Check the tires of the trailer to make sure they are not going flat. Check the wheels to make sure they are not hot to the touch. If the wheels are hot, it may indicate a brake or bearing problem.
Each day before you start check the lights to make sure they are working properly. Between trips clean the hitch and cables to keep them in good shape.
Never let yourself be interrupted when hooking up. Keep your mind on your work.
