Item Type: Cable Slit Tool Specification: Approx. 4 ~ 10mm / 0.2 ~ 0.4in Material: Hard alloy steel + tool steel, anodized aluminum steel structure Number of Cutter Heads: Single head Product Size: Approx. 131 x 40 x 26mm / 5.2 x 1.6 x 1in Cutting Depth: Approx. 5.5mm / 0.2in Diameter 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 ~ 0.4in A. 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.
