The load to be lifted is to be secured against slipping by suitable measures Before moving the lifting bag under the load it should be ensured that the side wall material is positioned between the top and bot tom plates Under no circumstances should the side wall material be between the load and top or the load and bottom during the lifting sequence This can under certain circumstances cause da mage to the side wall of the bag If the movement height or the movement area is not sufficient for correct application of the lifting bag then the required space can normally be quickly obtained by using the Vetter Mini Lifting Bag 8 bar 4 Operating Instructions 4 1 Operation with compressed air bottle 200 bar or 300 bar Connect the pressure reducer to the compressed air bottle 200 bar or 300 bar using the tommy screw 1 Close the presser reducer 2 Open the valve on the bottle 3 The pre pressure manometer 4 indicates the pressure in the bottle Adjust the back pressure to approximately 2 bar with the regulation bar 5 indication of the reduced pressure on the back pressure manometer 6 Connect the air hose of the pressure reducer via the nipple to the input coupling 7 of the controller In doing this press the nipple into the coupling until you feel it lock in For additional safety turn the brass sleeve 8 so that it is opposite the safety pin 9 Open the hand wheel 3 of the pressure reducer The
