VECTOR 3 M A N U A LMAN‐004 REV 7.2 80 7/20/2017abuse such as being dragged across a runway, a water landing or exposure to a lot of dust or sand. It’s important tomaintain the system even more frequently in humid, muddy or freezing conditions. If the Vector becomes immersed inmud or muddy water, clean the 3‐Ring release system with a mild solution of soap and water. Any rusted componentsmust be replaced.PROCEDURE FOR PERIODIC MAINTENANCE OF THE BOOTH 3-RINGRELEASE SYSTEM1. Yearly or as needed, operate the 3‐Ring release system on the ground. Extract the cable completely from thehousings and disconnect the risers.2. While the system is disassembled, closely inspect it for wear. Check the white locking loops (the ones that passover the smallest ring and through the grommet) to be sure they are not frayed.3. Check the hook and loop fastener on the cutaway handle and main lift web to be sure it is clean andadequately holds the handle.4. Check the cable ends for a smooth finish. The ends are finished at the factory to have a smooth, taperedsurface. This prevents the cable from hanging up in the loop. Check the cable ends and consult a rigger or themanufacturer if a burr or “hook” is present.5. Check the stitching, including that which holds the large rings to the harness.6. Check that all 3‐Ring release housings are firmly clamped (behindright ring cover and under yoke). The housing ends lie at thechest strap area, check for proper stretch by pulling downwardon them to confirm that they don’t move downwards more than½ inch. The end of each housing (at the end fitting) must be evenwith or up to 1” (25mm) longer than the top of the large ring.7. Take each riser and vigorously twist and flex the webbing near where it passes through each ring. The idea isto remove any set or deformation in the webbing. Do the same thing to the white loop.8. Check the housings for dents or other obstructions. Use the cable to do this.9. Clean and lubricate the release cable with a silicone spray. Spray on a paper towel and firmly wipe the cable afew times. A thin, invisible film should remain, too much will attract grit and dirt.10. Inspect the end fittings at the end of each housing. If one of these fittings were to come off the housing, ariser might release prematurely.11. If any wear is found, consult the United Parachute Technologies or a rigger before using the Vector 3.12. Reassemble the system. Double check it with the instructions in section 5 of this manual. Make sure the risersaren’t reversed. United Parachute Technologies appreciates and welcomes any comments from users thatrelate to the safety, operation or maintenance of the 3‐Ring release.1” to 2”Lowest possibleresting location
