Usage Steps 1.Place the product on the surface of the adsorbed workpiece. In hibernation state, press and hold the power button for about 2 seconds to turn it on; In standby mode, press and hold the power button for about 0.5 seconds to turn it on; 2.After starting up, the air pump automatically aspirates and reaches the set maximum pressure value (above 60kpa). At this time, the suction cup is adsorbed on the surface of the workpiece and can lift it up for operation normally; 3.The suction cup adsorbed on the workpiece surface will automatically detect the air pressure value. If there is a slight air leakage of the suction cup for a long time without operation, it will automatically start to replenish air when it reaches the set minimum safe pressure value (45kpa ± 5kpa). After reaching the set maximum pressure value, the air pump will automatically stop working. 4.Double-click the power button to relieve the pressure (shutdown). Remove the sucker after 2 seconds when it loses its adsorption force on the workpiece. The suction cup enters the standby state and sleeps after 10 minutes without any operation.
