OPERATION Interpreting the Lift Light When the vacuum lifter is ready to lift Never lift load unless lift the Maximum Load Capacity, the light is illuminated, vacuum lift light turns on automatically and because premature lifting could the vacuum pump turns off temporarily, to result in load release and personal injury. -
Page 26: Controlling The Lifter And Load
OPERATION Controlling the Lifter and Load When the lifter is ready, use the hoisting equipment to raise the lifter and load as needed. Use a control handle (circled in fig. 1A) to keep the lifter and load in the required position. Once there is enough clearance, you may move the load as required. -
Page 27: T O Rotate The Load
