You must check the coupling devices for general damage, missing parts, and functionality of _________.

Mounting Bolts:
- Look for loose or missing mounting brackets, clamps, bolts or nuts. Both the fifth wheel and the slide mounting must be solidly attached.
- On other types of coupling systems (i.e., ball hitch, pintle hook, etc.), inspect all coupling components and mounting brackets for missing or broken parts.
Locking Jaws:
- Look into fifth wheel gap and check that locking jaws are fully closed around the kingpin.
- On other types of coupling systems (i.e., ball hitch, pintle hook, etc.), inspect the locking mechanism for missing or broken parts and make sure it is locked securely. If present, safety cables or chains must be secure and free of kinks and excessive slack.
Fifth Wheel Skid Plate: Check for proper lubrication and that fifth wheel skid plate is securely mounted to the platform and that all bolts and pins are secure and not missing.
