Air Connection
AIR SANDER
Note: Air Compressor is not supplied. You will need an Air Compressor with a
minimum rating of one horsepower, 4 CFM delivery at 90 PSI, and a 12 Gallon Air
Tank. Refer to the above illustration for complete air connection setup.
You may use Quick Connectors, Quick Couplers, (not supplied) and Air Regulator
as shown in the Diagram above. Do not connect Couplers directly to the Air Inlet
(2). Doing so will increase the overall bulk of the tool and strain the Inlet Threads.
Be sure to follow all safety precautions as listed on Pages 2-4 of this manual and
the instruction manual for the Air Compressor being used.
This air tool requires lubrication during operation. For best results, it is recom-
mended to have an oiler and water lter in line with the air supply as shown in the
diagram above. This will extend the life of the tool.
To Attach Sanding Paper And The Pad:
1. Ensure that the Pad is rmly screwed onto the Drive Spindle (38). The
Spindle Lock (41) turns to engage the Drive Spindle (38), allowing the
Pad (44) to be threaded on securely. Turn the Spindle Lock (41) back out
of the way before use. If the Orbital Hub is still in the locked position
during use, then the Sander will not operate properly. (See Bottom
View, next page.)
2. The Sander only uses 6” diameter, PSA Stick, (self-sticking) Sanding
Paper (not included). Make sure to attach the Sanding Paper rmly to
the Pad (44).
