1. Before use, carefully inspect the instrument, glass bottle for any damage, and ensure that all interfaces are in compliance. Handle with care.

2. The PTFE switches everywhere should not be tightened too tightly, which may easily damage the glass.

3. Each interface should not be tightened too tightly. It should be loosened and flexible at regular intervals to avoid prolonged tightening that may cause the connector to bite

4. It is necessary to purchase genuine accessories from the original factory, and the indiscriminate use of other accessories can pose a life-threatening danger to the machine.

5. After stopping the machine, loosen each PTFE switch. Staying still for a long time in working condition can cause deformation of the PTFE piston.

6. The electrical part must not be exposed to water or moisture.

7. First turn on the power switch, then let the machine run from slow to fast. When stopping, make sure the machine is in a stopped state before turning off the switch.

8. Regularly clean the sealing ring by removing it, checking if there is any dust or dirt on the shaft, wiping it clean with a soft cloth, then applying a small amount of vacuum grease and reinstalling it to keep the shaft and sealing ring smooth.

9. After each use, various oil stains, stains, and solvent residues left on the surface of the machine must be wiped clean with a soft cloth and kept clean.

10. Wipe each interface with a soft cloth (which can be replaced by a napkin), and then apply a small amount of vacuum grease. (After using vacuum grease, be sure to cover it well to prevent dust and sand from entering.)

11. When repairing or inspecting the machine, be sure to first cut off the power and water sources.
