Did anyone know that this very small but very important 3-ring-system requires maintenance. I am not kidding!<\/span><\/strong><\/h4>\n\n\n\n
<\/div>\n\n\n\n
The 3 ring-system is a skydiving safety device invented by Bill Booth in the mid 1970s. When we have a malfunction and need to cut away, the cutaway handle is pulled and the cable slides to release the riser\u2019s locking loop. This allows the small ring to release from the medium ring and then the medium ring to release from the big ring. Then you will fall away from the bad parachute that is attached to the risers! <\/p>\n\n\n\n
So, due to all this heavy loading, it is important that 3 rings are worked from time to time, especially during winter.<\/p>\n\n\n\n

Regular Maintenance<\/span><\/h3>\n\n\n\n
Manufacturers recommend regular maintenance of the 3 ring-system. How do we do it? There is a video at the end of this article, below is a description\u2026<\/p>\n\n\n\n
First, you need to disconnect the risers from the harness. To do that, remove your cutaway cable! \u2026WAIT!!!…<\/li>
Do not remove your cutaway cable before you remove the RSL attachment! You do not want to activate the reserve opening, we are just doing regular maintenance.<\/li>
Now, check the Velcro attachment for the cutaway handle is in good shape, still sticky, not worn away. It holds the handle. And do make sure none of the hooks are touching any of the harness webbing.<\/li>
If you have a silicone spray, it will be good to clean your cutaway cable with it now; if not, you can just clean it with a soft towel. Your rigger will clean the cables with silicone during the reserve repack.<\/li>
Have a look at your rings and make sure there is no dust, mud, or rust, it won’t hurt to clean them with a towel.<\/li>
One riser at a time, twist webbing on each ring that goes through. Why do we need to do this? To remove any set or deformation on the webbing. Why? So, the ring on the 3 ring-system works smoothly.<\/li>
The locking loop, the white material that attaches the risers to the harness, do the same as you did on the risers, pull, flex, and look that it is still intact.<\/li>
Going back to the cutaway cable, look at the top ends of the cable to make sure they are smooth. If there is any sharpness, please ask your rigger to have a look!<\/li>
One more part to have a look is the 3-ring release housing, make sure there is no sharpness and it is not bent.<\/li><\/ul>\n\n\n\n

Examples of 3-ring Issues<\/span><\/em><\/h4>\n\n\n\n
Below are some real problems found on rig maintenance. All of these 3-rings are unsafe to jump and require replacing or renewing. <\/p>\n\n\n\n
