Air Pressure Supply

This tool is designed to operate with a maximum air pressure of 90 PSI. You must use an air regulator, set at 90 PSI or below.

In use, this tool will use, on average, 7 Cubic Feet per Minute of compressed air at 90 PSI. For satisfactory performance, you must use an air compressor capable of delivering this volume of air at the stated pressure.

We recommend that you use both a filter and an inline oiler in your air supply system as illustrated in the diagram below. These components are not included with this tool, but are available from Harbor Freight Tools.

If you do not use a filter and inline oiler, put a few drops of water displacement oil into the air line before each use. After each use, the Palm Sander should be carefully drained of collected moisture and sprayed with a water displacement oil.

We recommend that you install a quick-release nipple (not included) into the Regulator. Quick release connectors at all points in an air pressure system make your work easier.

Operation

Installing the Sanding Pad

1.Disconnect the air hose from the tool.

2.Select the appropriate sanding pad (not included), and press it onto the Backing Pad (31). NOTE: You should always start with a sanding pad coarse enough to remove saw marks and do preliminary shaping of the workpiece. Then sand the workpiece with progressively finer grit sanding pads until the desired surface is achieved. Do not move directly from a coarse grit sanding pad to a much finer grit sanding pad. Doing so wastes time and causes additional wear on you and the tool.
