Inspection of the Premier 690 Coupling
Important: Before servicing the Premier coupling, refer to the Premier web site at www.premier-mfg.com for complete safety, operation, and maintenance instructions.
Warning: If at any time the 690 coupling is bound up (jackknifed), the 294 bolt MUST be replaced immediately! Do not use the coupling until the bolt has been replaced.

Failure to do so may result in trailer separation from the truck while in use, resulting in serious personal injury or property damage.
