Press the "O" switch to make sure your PaintEater is turned off. Plug its cord into a regular 120 volt outdoor or extension cord outlet. Put on your respirator, gloves and safety goggles.
Position your hands on the PaintEater housing so that you have a solid, comfortable grip on the machine; you can use the strap, the folding handle or the top of the housing for your dominant hand, and either leave your other hand free or use it to steady the unit.
Press the "I" switch to turn the unit on.
Place the rotating disk flat against the surface to remove large paint chips or to prepare the edge between removed paint and adhered paint that cannot be removed because it is beyond the reach of the PaintEater. Use the edge of the pad to remove stubborn paint chips or to get under the edges of siding panels. Run the machine back and forth over the surface until you see only unfinished wood.
Check the disk periodically to make sure that it is not clogged with paint. Clean it by quickly running it over a concrete sidewalk or block.
Continue to run the unit over the surface until all paint has been removed.
Replace worn fiber abrasive discs by pressing the disc lock at the bottom of the unit and turning the disc counterclockwise to remove the old one, and then keeping the lock pressed as you attach the new disc by placing it on the shaft, turning it clockwise and tightening it by hand.
