Installation Instructions
- Straighten the cable and cut the end square using cable cutter.
- Apply forward pressure until you feel the ball bearings land in a corrugation valley. Reverse tool to remove. End of the prep tool can be used as a guide.
- If all of the outer jacketing wasn’ t removed during initial cabl prep remove at this time. Slide the clamping nut over the cable end. Install pre-lubricated o-ring in the 5th corrugation.
- Push the collet back over the O-ring until it stops, then release it. Verify that the collet has located into the first corrugation. DO NOT TWIST. Clean off face of foam with alcohol wipe.
- To achieve optimum Return Loss, pull outer body to remove coring bit from the tool. Place bit over inner conductor and push forward until bit contacts face of foam. BEFORE turning drill push HARD depressing foam. Maintaining force, turn drill at 1 /4 trigger until tool bottoms out. Clean foam from coring bit and repeat, carefully remove any loose foam with non-metallic tool.
