Place the suction cup on the contact surface, pump the plunger, and when the red line is hidden, the vacuum is sufficient.
To release, simply press the trigger on the end of the handle opposite the plunger.
Note: Avoid oil, grease or water on the surface of the lifting object; if the red line appears during lifting, please put down the object as soon as possible and pump the plunger to improve the vacuum.
Package Included:
1x Vacuum Suction Cup.
