- Never attempt weld repair of damaged or worn drawbar eyes or front end housings

- Clean and inspect drawbar eyes and eye housings for damage or excessive wear before each and every use

- All welds should be performed by a certified welder skilled in structural welding practices

- Drawbar structure as well as welds attaching front end housing to drawbar must be of sufficient strength to withstand the load rating of the drawbar eye

- Do not bind-up (Jackknife) any application as stresses can cause damage to products or components, resulting in failure and detachment of the trailer while in use
