Possible issues with the leg extension on the TuffStuff CFM-500 include:

1. Incorrect routing or securing of the Leg Extension Cable (#12) through the pulleys (#26-Labeled I and J), which could affect movement.
2. Loose or improperly fastened hardware such as Hex Head Cap Screws (#50, #63), Flat Washers (#45), or Nylon Insert Lock Nuts (#48, #64).
3. Worn or damaged pulleys or bushings, which should be checked regularly.
4. Improper cable tension, which may need periodic adjustment.
5. Lack of lubrication on moving parts or using oil-based lubricants, which can cause buildup and hinder performance.
6. Malfunctioning Push Pull Pins (#62, #82) if springs are not operating freely or nuts are not fully fastened.

Each of these can affect the proper function of the leg extension mechanism.
