NOTE: 1. This equipment is a fragile product, please handle it carefully when using it. 2. When using vacuum grease on rotatable parts such as glass cock or feeding tube, please choose a smooth and viscous brand. 3. Please apply the soft vacuum grease evenly and thinly on the valve core, so that the grinding port is fully matched. 4. After long-term use, the grinded parts where vacuum grease has been applied will oxidize or harden the grease, which may cause difficulty in rotation or stickiness of the grinded parts. Therefore, before the grease hardens, please regularly remove the parts and wipe off the grease on them with a paper towel, and then use toluene and xylene and other solvents to carefully wipe clean. After the solvent has completely evaporated, re-apply new vacuum grease. 5. If the grinding mouth has been tightened or stuck, forcibly disassembling at this time will cause the glass to break, which is very dangerous. When sticking occurs at the grinding mouth, please use heating (hot water, blowtorch) to soften the cured vacuum grease before disassembly.
