Products cleaver knife method of operation to confirm the device blade sliding plate in front of one end, open size platen; fiber coating stripped with stripping fiber clamp reserve bare fiber length of 30-40mm, dipped in alcohol absorbent cotton or cotton wrap the optical fiber, the fiber is then wiped clean. Wiping with cotton wool or tissue, do not use the same cotton wool or tissue paper to rub the second (Note: Please purity greater than 99% alcohol). Visual fiber coating edge aligned with the cutter ruler (12-20cm) of appropriate scale, the left hand of the optical fiber into the pilot pressure tank the bare fiber straight on the left and right rubber mat. 4 together on a small plate, large platen, to promote the device blade slider, the blade dicing the lower surface of the optical fiber, and is free to slide to the other side, cut off the fiber; 5, his left cutter right hand to open the large platen removal of fiber debris into the fixed container. 6, with the left hand and hold the fiber while his right hand to open the small pressure plate, carefully remove the fiber cut end face Note: neat cross-section of the optical fiber is not to touch and it matter. Product attributes to adapt to fiber single-core silica fiber to adapt to the coated optical fiber diameter φ0.25 & φ0.9 to adapt to the fiber cladding diameter 125μm cutting fiber length 9 ~ 16mm (φ0.25) 10 ~ 16 (φ0.9) Dimensions 59mm (W) * 55mm (D) * 49mm (H) Weight 255g cutting angle adaptation value ≤ 0.5 ° edge life 12000 Description 1, Fibre pressing base and blade cleaning methods frequently moistened with alcohol cotton swab to clean the rubber surface of the fiber-optic pressure seat and the edge portion of the blade, in particular, cut ineffective, shall be promptly cleaned. 2, the method of changing the blade position of the cutting effect is deteriorated to be changed the position of the blade i.e. effective position point A rotating blade, the cutting knife as a whole is inclined at 45 degrees, and releasing (without removing) the screws I toolholder surface B, with cotton swab or other sharp objects withstood the small holes on the surface of the blade, rotary blade, the blade rotation to 1-12 or 1-16 effective position of point C light to press and hold the blade with your fingers, tighten the screws on the turret, must be sure they are tight. 3, the blade height adjustment transactions described in the circle of the blade for the rule, any point on the circle from the theory Jieneng cutting more than 1,000 times, ,1-12 or 1-16, the region between the cutting operation can also select the number of points .
