Three Blade Stripper is used to strip cable, the knurled portion is pressed on the upper jaw to open the stripper's jaws. The cable is inserted through the V-block until the cable reaches the V-shaped cable guide. The upper jaw must be released to close the jaws. Then index finger is inserted into the stripper's finger ring and turn the stripper clockwise 3-5 times. The cable's insulation is finaly cut after turning the stripper. To expose the inner conductor, the outer jacket and dielectric must be pulled away. The stipping length is preset to 8mm. To strip other lengths, the blades position must be adjusted. The blades' depth may be adjusted by inserting the hex wrench into the blade depth adjuster on the bottom of the tool. To cut smaller cable, rotate the hex wrench clockwise. To cut larger cable, rotate the hex wrench counterclockwise.
