1., be sure to protect the head (glass fiber perforator hole one, usually copper plating, the upper end of the thread, you can loose the lemon tight) can not be broken. When the utility model is used, the head is aimed at the movable pulley on the small frame, and is worn out by the pulley, and then the thread, the pull wire and the dredging pipeline are carried out. If encounter will threader all out of the frame, should pay special attention to a head is the last card in the small frame of the ring, the ring is closed when the disc punch head with fixed traction, so be careful when you break out in the traction head, in the coiling punch when first the traction head stuck in the middle ring.
2. glass steel punch for hard brittle material properties, so you should use in the process of maintaining its bending the minimum diameter of not less than 60 cm in the pipeline or other construction environment, in the pipeline to the right angle or less than 90 degrees, should pay special attention to protecting the traction head can not be broken out, well when you should take some measures to prevent the damage of threading device. (such as placing, stringing, pulleys, matching, etc.) in the corner
3. glass steel punch can withstand temperature range -40 to +80 degrees, the construction should avoid any improper behavior, such as contact object or environment of cold or hot products, after use should be placed in a cool place, avoid long time exposure to sunlight, rain shower.
4. the maximum linear pulling force of the glass fiber perforator is 2.5 tons. It is not possible to use a high power machine for traction at the right angle of 90 degrees, otherwise it may break. Must not let the vehicle and other heavy things roll, otherwise can shorten its service life greatly.
In 5. large cable used in the construction of punch, punch can not be used directly for the application of traction cable, perforated metal traction head in the pipe by pulling a rope, and then use the wire rope traction cable, this punch life will be greatly improved, recommend the use of various stringing to improve work efficiency and protect the threading device.
