How to use a hardwood Drum sander. Becareful, you can seriously injure yourself and others, if, you use this hardwood refinishing flooring tool, incorrectly.
Belt and drum sanders are designed pretty similar to each other. You have a drum in the front, where you load your paper, motor on top with a 60 foot power cable, long control arm for the handle and lever, with a dust bag attached to it. Some are equipped with a 110 or 220v motor. Operating them is similar. Use the control lever to lower and raise the drum. Feed it, forward and back. Dust bag gets full, you empty it.

Let's pretend the cable is on the right side and the machine sands, heavy on the left side of the drum sander. Sand with the grain of the wood floor. Power up the machine, slowly start moving forward at the same time lower the drum control handle - feather touch. Once you feel the drum, touch the flooring, slowly and gradually release the lever, and proceed forward, at a slow constant speed. As you approach the wall begin to raise the lever gradually.
Note: Avoid bumping into the wall, this will apply pressure to the front of the sander downwards, resulting in gouges.
Start to move backwards, lower the lever - feather touch, then start to sand backwards. As you return to your starting point raise the lever gradually. You can have someone assist you with the power cable, to prevent tripping over it.
