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.
