Cable and fusable links
Kory,
Have you tried to turn down the pressure on your machine. I adjust the pressure using the unloader valve to the point the burner comes on. I use chemical(hot chemical can melt some links) and hit the cable and links directly. Never had any problems as of yet, dont know the psi but its not much. When I first started cleaning I cleaned inside with 4000 psi, to much water to much pressure, now I clean with minimal pressure its just easier.
