Operation is subject to the followingtwo conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that maycause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radiocommunications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: SF-10 0102 Basic Information Please read this manual carefully before operating the equipment. Follow all safety instructions and warnings contained in this manual. Warnings and Precautions OPTICAL FIBER CLEAVER Electric precision Accessories list: Host :1 set/Miller stripper :1 piece /alcohol bottle :1 set/Instruction :1 copy/ Type-C charging cable :1 set Warning: If this document is ignored, it may cause personal injury or damage to the equipment due to improper use. Safety glasses should always be worn during fiber preparation and cutting. If fiber fragments come into contact with the skin or eyes, there is a risk of personal injury. Attention: 1.Do not disassemble or modify the fiber cleaver. 2.The fiber cleaver is designed for cutting glass fibers used in communications, do not attempt to cut any other material. 3.The cutting blade is very sharp, please do not touch it, otherwise it may cause personal injury. 4.Never expose the fiber cleaver to rain or moisture.

Note the position of the plastic skin shown in the figure 1.The outer plastic skin of the tail fiber is stripped off 33-38mm with Miller stripper, and the strengthened velvet is cut off with scissors. Then the middle plastic skin is stripped off 28- 33mm with Miller stripper. Finally, the fiber coating of 28-33mm is stripped off with the smallest mouth of Miller stripper, and the fiber is wiped clean with alcohol. 2.Put the clean optical fiber into the holder base. Note the position of the plastic skin shown in the figure. 0708 Manual cutting: Place the prepared optical fiber, press the cutting button on the fiber cleaver or the "Cutting Optical fiber" button on the APP, and the fiber cleaver will cut the optical fiber by itself. Manually cut optical fiber button (long press 1.5 seconds to reset the fiber cleaver) The two buttons here are equivalent to the cutting button function on the machine Fiber waste disposal: P…
