Feature:1. Made of hard alloy steel and tool steel materials, with anodized aluminum steel structure, drum-shaped cable follower can ensure the stability of the cable during the stripping process, easy to operate along the cable direction2. Adjustable blade, angle can be rotated 90 degrees, equipped with pulleys, longitudinal stripping along the wire direction, labor-saving and stable operation3. The tool is designed with an accuracy adjustable blade to avoid damage to the optical fiber. Adjustable peeling outer diameter from 4-10mm, cutting depth 5.5mm. Suitable for different cable thicknesses. The tool can be replaced by a blade4. The tool design is suitable for many core sheathed or armored cables. The main purpose is to cut the outer sheath of the cable to obtain the internal optical cable. Used to install wires into network and telecommunications equipment5. Cable slit tool come with comfortable grip, ergonomic handle, easy for you to operateSpecification:Item Type: Cable Slit ToolSpecification: Approx. 4 ~ 10mm / 0.2 ~ 0.4inMaterial: Hard alloy steel + tool steel, anodized aluminum steel structureNumber of Cutter Heads: Single headProduct Size: Approx. 131 x 40 x 26mm / 5.2 x 1.6 x 1inCutting Depth: Approx. 5.5mm / 0.2inDiameter Ranges of the Model Cables Corresponding to the Colors of the Guide Wheels: Gold: Approx. 8 ~ 28.6mm / 0.3 ~ 1.1in Red: Approx. 4 ~ 10mm / 0.2 ~ 0.4inA. Determine the cable structure.1. The many core optical cable structure may have a solid inner adjacent sheath and an outer adjacent armor sheath. In order to avoid tool damage, please determine the structure of the cable first.B. Set the cutter head.1. The slitting blade of the utility knife is equipped with a retractable function. When the sample cable is placed in the utility knife, the depth of the blade can be set. There is a groove at the bottom of the thumb knob A, and the blade can be adjusted by turning the upper screw the height of. There are 10 divisions at the bottom of the thumb knob. The height of the cutter head adjusted by one turn is 1mm. In turn, each scale is equal to 0.1mm. When the distance between the cutter heads is adjusted, the utility knife will have a "lock" on the cable. The sound of "live" can avoid the damage of the internal structure of the cable caused by setting the cutter head too deep.C. Tool Knife Operation: According to steps 1-6, it can be used for internal and external structures with relatively high strength. (longitudinal cutting)1. Loosen the black thumb nut "A" and rotate the blade to move it longitudinally. (as shown in the figure, the blade cuts radially)2. Put the cable into the loose tool and adjust the yellow finger knob "B" to an appropriate position.3. Tighten the black thumb nut until the blade can cut the cable longitudinally.4. Strip the cable sheath longitudinally when pulling the tool. If it is used for a hard cable sheath with "lay", you can slightly rotate the blade to adjust it according to the hardness of the cable.5. Loosen the black finger nut, then rotate the tool 180 around the cable, and re-tighten the black knob for the second longitudinal cut.6. Use diagonal pliers or a screwdriver to separate and trim the cut cable.7. If you need to cut cables with a stronger sheath, stop at step 6.8. The following additional steps are suitable for cutting cables with stronger sheaths. (optical cable cutting)9. For the cutting of the optical cable, longitudinal cutting of the center of the optical cable sheath can be carried out, and the tool can be slided to a predetermined position.10. Loosen the black finger nut "A", rotate the blade 90 to set the radial cutting, and re-tighten the black knob to set the blade depth.11. Rotate the tool around the optical cable to cut.12. The cable has now been pulled out and then trimmed..Package List:1 x Cable Slit ToolNote:Caveat! This stripping knife can not be used on the electrified cable, it has no anti‑shock function! The wire stripper is in compliance with OSHA/ANSI standards and is recognized by the industry as being eye‑protective. This tool cannot be used in situations other than those defined in this manual. You must carefully read and understand the contents of the manual before use.
