To operate the sander:
1. Plug the tool into compressed air.
2. Hold the sander and press the throttle lever
(Figure 4) to operate the sander.
A filter/lubricator/regulator set up is not recom-
mended, as excess oil in the tool could spray onto
the workpiece.
Run the sander for a few minutes to eject excess
oil, then wipe the tool down with a rag and begin
sanding. Oil the tool after use or storage.
