FLSO Orbital Sander
Orbital Sander
An Orbital Sander is a power tool used to smooth surfaces by abrasion with sandpaper. Orbital sanders have a means to attach the sandpaper and an electric motor to move it rapidly, contained within a housing with allows it to be hand-held and maneuvered across surfaces or edges to be sanded. In the SOA, we have three types of Orbital Sanders. One type uses round sanding discs that have a perforated “Velcro”, or “Hook and Loop” attachment method. Another uses round, adhesive-backed sanding discs, and the third type has a square, rather than round base, which uses ¼ pieces of standard sandpaper sheets. This third type is called a ¼ sheet sander, and will be described later in this document.

Repeat steps 1 through 5 above, however, there is no need to align holes in the PSA discs, since there are none.
Power Switch (Fig. 2)
To reduce the risk of injury, make sure the sander is not resting on the workpiece when the switch is turned on. To turn the unit on, depress the side of the dust protected switch that corresponds to the symbol “I”. To turn the tool off, depress the side of the switch that corresponds to the symbol “O”.
The Power Switch is the same on all three types of orbital sanders in the SOA.
To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

2. While holding the canister, twist to unlock and remove the adapter. (Fig. 3)
3. Gently empty the bag and shake out the adapter. (Fig. 4)
Note: You may notice that all the dust will not come free from the bag. This will not affect sanding performance but will reduce the sander’s dust collection efficiency. To restore your sander’s dust collection efficiency, depress the spring inside the dust bag when you are emptying it and tap it on the side of the trashcan or dust receptacle. Never operate this tool unless the dust collector is in place. Sanding dust exhaust may create a breathing hazard.
To operate your sander, grasp it as shown in figures 5 or 6 and turn it on.

To produce the best finish possible, start with coarse grit sandpaper and change gradually to finer and finer paper.
¼ Sheet Sanders
The ¼ Sheet Sandersin the SOA are similar in function to the Orbital Sanders, but have square pads instead of round ones, so they can reach into corners. Lab Technicians must be consulted regarding set-ups for these.
