0 0 <br /> Field cutting and tapering Observe the following procedures while operating the Taper Maker. <br /> (continued) Observe <br /> Check blade angle by using a factory taper as gauge.A properly adjusted <br /> blade should be in contact with the taper over the entire taper length. If <br /> adjustment is required, loosen the blade retaining screws and adjust the <br /> blade angle with the set screw. <br /> • Mark the proper taper length on the pipe surface. Refer to <br /> Taper Length Table. <br /> • Insert the threaded collet shaft through the base casting and the mandrel. <br /> • Select the appropriate size collet and slide it onto the mandrel, making sure <br /> the key inside the collet engages the slot of the mandrel. <br /> • Hold the collet and turn the collet control knob clockwise until collet begins <br /> to expand. Note: It may be necessary to adjust the cutting head to <br /> accommodate different size collets. <br /> • Insert the collet into the pipe until the back end is flush with the end <br /> of the pipe. <br /> • Expand the collet to grip the inside of the pipe by turning the collet control <br /> knob clockwise. <br /> • Lower the cutting blade until it contacts the pipe by turning the cutting head <br /> adjustment handle clockwise. <br /> • Using the ratchet handle,turn the tool clockwise, gradually lowering the <br /> cutting blade by turning the cutting head adjustment handle clockwise. <br /> Continue until a smooth taper of the proper length is obtained.When <br /> complete,the thin edge of the taper should not be less than 0.030 inch <br /> (1/32 inch or 0.75 mm)thick. <br /> • Contract the collet by turning the collet control knob counterclockwise and <br /> remove the tool. <br /> Note:The carbide cutting blade has four cutting edges.The blade can be <br /> turned and/or reversed by loosening the cutting blade retaining screws and <br /> removing the blade. When reinstalling the blade, make sure the blade is tight <br /> and flush with the guide. Blade angle must be checked. Replacement blades <br /> are available from your distributor.
