How to Use:

1. Place the suction cup on the contact surface so that the red line can be seen when lifting the load.
2. Pump the plunger until it is fully connected. When the red line is hidden, it indicates that the vacuum is sufficient.
3. If the red line appears during lifting, please immediately put down the load and pump the plunger until the red line is hidden again.

Notes:

1. Please always inspect vacuum suction cups before use. Clean them and the load surface with soap and water with a clean sponge or lint-free cloth. Make sure both surfaces are dry and free of any dirt or obstruction. Make sure the handle pump has enough lubrication for the pump. Please check whether the elasticity of the vacuum suction cup is good and whether there is damage and obvious abnormal distortion.
2. Before use, please test the suction of the vacuum sucker on a small piece of material.
3. Please allow the slight color difference caused by the shooting light and 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
