The tube must not have any cuts on its periphery. Use a tube cutter TK-1, 2, or 3. Do not use a pair of pliers, nippers, or scissors because they could resul t in an uneven cut or cause the tube to become flattened. As a result, it might not be possible to connect the tubing, or after the tube has been connected, it could pull out or allow air to leak. Make sure to cut the tube with sufficient length. 2) Grasp the tube, push it in slowly, and make sure to insert it to the hilt. 3) After inserting the tube to the hilt, pull the tube lightly to make sur e that i t w i l l not come out . I f the tube i s not inser ted all the way, it could be pulled out or cause air leakage. 2. Removing of the tube 1) Fully push in the release bushing. At the same time, push the collar evenly. 2) Keeping the release bushing pushed so that it will not retract, pull out the tube. If the release bushing is not pushed in sufficiently, it could wedge in further, making it difficult to pull out the tube. 3) The removed tube can be reused by cutting off the portion that was wedged in. If the tubing is reused without cutting off the wedged portion, it could lead to air leakage, or the inability to remove the tube. 1054
