Here is a step by step walkthrough of how to operate Hapman’s Bulk Bag Filler.
First, you place the bag straps on the retention arms of the Bulk Bag Filler.
Then you place the spout over the bladder. Once that’s in place, you push the “inflate” button to inflate the bladder, which creates a dust seal during the filling process. The bladder holds the spout up while the bag is being filled.
When you are finished, hit the “deflate” button to deflate the bladder.
Lastly, pull the spout off the fill tube, tie the fill spout and remove the bag from the frame.
