General Safety Note: For all cutting/turning tools: -Cutting tools have sharp cutting edges as its characteristic. Please wear protective gloves to avoid the possible injuries caused by direct hand touching of cutting edges. -Please read the operation manual book and the product catalogue before the operation. Please use the recommended operation methods and technical parameters as reference. Also, please do use the safety face cover or goggles for protection to avoid the broken pieces might cause by improper operation methods or working conditions. -Please do use the safety face cover or goggles for protection to avoid the scattered broken pieces might cause by overloaded impact of force and excessive abrasion to the cutting tool. Please replace the cutting tools promptly to enable further operation running normally. -Please do use the safety face cover or goggles for protection to avoid injury or burns caused by the split of high-temperature chips. When removing chips, please make sure the machine is not running and workers are wearing protective gloves while cleaning chips. -Tools and materials reach high temperatures during cutting operation. Please do use protection gloves to avoid burns caused by direct touch to the tools and materials after cutting shortly. -During the process of cutting, sparks will be generated. Sparks and high-temperature chips may cause fire. Please do not operate around hazardous zone where has the possibility of fire or explosion caused by sparks and overheated chips. In the case of using oil cutting fluid in CNC lathe machine, please make sure there is sufficient fire-protection equipment surround the operation area. -With the high speed operation condition, dynamic disequilibrium or vibration of the chuck within the CNC lathe machine will cause damage to cutting tools. Please do use the safety face cover or goggles for protection to avoid injuries. Please do carry out trials to confirm that whether there is vibration or unusual sound and movement within trials. -Please do not touch the finished workpie
